ELE Times - Mon, 01/08/2024 - 13:47

In a strategic move to fortify its position in the electronics manufacturing sector, the government of Tamil Nadu is set to unveil the Semiconductor and Advanced Electronics Policy at the upcoming third edition of the Global Investors Meet, taking place from January 7 to January 8. This announcement follows similar initiatives in Odisha and Gujarat, signalling a concerted effort to propel the state’s electronics manufacturing value chain.

M K Stalin, the Chief Minister of Tamil Nadu, will officially launch the policy, which is meticulously designed to attract investments from companies specializing in sophisticated electronics design and cutting-edge manufacturing. The government has pledged to provide incentives and subsidies based on a predetermined percentage to entice prospective investors.

The Global Investors Meet, a prestigious event drawing attention from top economists and industry leaders, will be graced by luminaries such as Raghuram Rajan, former governor of the RBI; Arvind Subramanian, former Chief Economic Advisor; celebrated author Chris Miller; business tycoon Anand Mahindra; Mark Widmar, CEO of First Solar; and Jeff Magioncalda, CEO of Coursera, among others.

Industry experts assert that this policy is a critical necessity as Tamil Nadu aspires to enhance the entire value chain within the sector. The focus extends from generating crucial jobs in component manufacturing to semiconductor design and electronics manufacturing services (EMS).

Speaking exclusively to the media, an unnamed senior government official emphasized Tamil Nadu’s advantageous position in attracting semiconductor investments, citing the presence of global giants like KLA and Qualcomm. The forthcoming policy is anticipated to reinforce the state’s commitment to achieving excellence in electronics manufacturing while extending lucrative subsidies and incentives to firms choosing to invest in Tamil Nadu.

The official also highlighted the dichotomy in job offerings within the sector, stating that while EMS provides a larger number of jobs, the pay scale is comparatively lower. On the contrary, electronics design offers high-paying jobs for highly skilled individuals. Over the past years, Tamil Nadu has successfully courted major players, including Apple’s contract manufacturers Pegatron and Foxconn, Tata Electronics from India, and Taiwan’s Delta Electronics, solidifying its position as the preferred destination for global electronics investments.

As the government positions Tamil Nadu at the forefront of electronics manufacturing, the Semiconductor and Advanced Electronics Policy is poised to play a pivotal role in attracting top-tier talent and global investments, setting the stage for a transformative period in the state’s industrial landscape.

SensorTile.box PRO, a new story about a professional board and how we can all be IoT heroes

ELE Times - Mon, 01/08/2024 - 11:25

Author: STMicroelectronics

The SensorTile.box PRO redefines what it means to use professional tools destined for the Internet of Things by making the technology accessible to more than just embedded systems engineers. That’s why ST brought this new development tool to numerous academic events, fairs, and contests. As we look back at the reception the SensorTile.box PRO received in 2023, we wanted to use the blog to share the stories that took place behind the scenes and the transformations we witnessed as people who never thought of themselves as IoT engineers suddenly started to create applications, use sensors, and send data to the cloud by leveraging its processing and connectivity capabilities.

The story told by the new SensorTile.box PRO

Denise Sanfilippo, Application Development EngineerDenise Sanfilippo, Application Development Engineer

Lisa Trollo, MEMS Sensors ecosystem and digital marketing manager Lisa Trollo, MEMS Sensors ecosystem and digital marketing manager

Michele Ferraina, Software Application EngineerMichele Ferraina, Software Application Engineer

A path to IoT for newcomers

One of the first times we publicly introduced a SensorTile.box PRO was at the “Big Hack”, an event held at the Apple Developer Academy in Naples, Italy, on July 2, 2023. ST gave samples to four teams who had 24 hours to develop an application. Interestingly, these were macOS and iOS software developers, not traditional IoT engineers. Hence, they had far more limited experience with low-power sensor boards. However, the entry and expert modes of the SensorTile.box PRO made the board powerful while remaining accessible to ensure the creation of exciting applications. The winner designed Wakey, an application for people suffering from somnambulism, to provide valuable help for the well-being of users and to help avoid potential injuries.

The upgraded modes of the SensorTile.box PRO

Just like the SensorTile.box announced in 2019, the SensorTile.box PRO includes three modes: Entry (Mode 1), Expert (Mode 2), and Pro (Mode 3). However, the newly released model brings more features. For instance, Mode 1 now includes new machine-learning applications, such as human activity recognition, an in-vehicle baby alarm, or free-fall detection, among others available on GitHub. The SensorTile.box PRO also features a new user interface mechanism called QTouch. It uses the Qvar technology, which connects two electrodes to measure quasi-electrostatic potential variations. In this instance, the probes can detect a swiping motion and use it as a user interaction.

The realization that IoT has become more accessible

Michele holding the SensorTile.box PROMichele holding the SensorTile.box PRO

The team behind Wakey at the Apple Developer Academy relied on the Expert mode to build their application. On the SensorTile.box PRO, Mode 2 now includes new power optimizations that only wake up the sensors in use and enable users to tweak data extraction and processing to ensure accuracy while keeping the power draw to a minimum. Thanks to the new features in Mode 2, developers at the Apple event could focus on writing their applications instead of learning how IoT systems work. Because they could just rely on the intelligence driving the SensorTile.box PRO in Expert mode, the contestants only focused on capturing and processing data as the board managed the rest.
The message sent to all in the industry by ST Overtures to Arduino and Zephyr

Another impactful event took place in October at the Department of Mechanical Engineering at Politecnico di Milano, where Lisa Trollo, responsible for MEMS Sensors Ecosystem and Marketing Communication at ST, walked the students through a presentation on MEMS in the context of sustainability. The event was also held in collaboration with Arduino as the SensorTile.box PRO is fully compatible with the platform. It’s another testament to ST’s desire to make the SensorTile.box PRO accessible to all. That’s why we are also working on supporting Zephyr and will update this blog post when it happens.

Prelude to a new way of building IoT products

Consequently, as the SensorTile.box PRO redefines what “PRO” means in the context of IoT, we saw a new sort of interaction at events like Maker Faire Rome 2023 last October. Attendees would experience the board and start asking questions about the workings of an accelerometer and how it could help solve their challenges. Put simply, by significantly lowering the barrier to entry, we saw new companies exploring IoT in ways they never had thought possible before. Additionally, once these teams finish their proof of concepts, we can refer them to the ST Partner Program, where they can find designers, implementers, and manufacturers to help them bring their ideas to a commercial reality.

Approaching IoT from a low-power machine-learning angle

Politecnico di Milano also saw Denise Sanfilippo, an application development engineer, show a demo running on the SensorTile.box PRO. It used the LSM6DSV16X in an embedded sensor fusion low-power application and Qvar to control a joystick and virtual button in a gaming setting. It was thus a unique opportunity to show why ST chose this specific bill of materials for the new SensorTile platform.

Indeed, from sensors like the LIS2DU12 accelerometer and the the LPS22DF pressure sensor to the STM32U585AI microcontroller as well as the BlueNRG355AC Bluetooth LE 5.2 SoC and the ST25DV04K NFC tag, all contribute to a low power consumption. Moreover, the sensors offer performance compatible with applications featuring machine learning at the edge, and the arrival of the NFC tag opens the way for new communication vectors and user interactions.

Partitioning to optimize AI inference for multi-core platforms

EDN Network - Mon, 01/08/2024 - 09:22

Not so long ago, artificial intelligence (AI) inference at the edge was a novelty easily supported by a single neural processing unit (NPU) IP accelerator embedded in the edge device. Expectations have accelerated rapidly since then. Now we want embedded AI inference to handle multiple cameras, complex scene segmentation, voice recognition with intelligent noise suppression, fusion between multiple sensors, and now very large and complex generative AI models.

Such applications can deliver acceptable throughput for edge products only when run on multi-core AI processors. NPU IP accelerators are already available to meet this need, extending to eight or more parallel cores and able to handle multiple inference tasks in parallel. But how should you partition expected AI inference workloads for your product to take maximum advantage of all that horsepower?

Figure 1 Multi-core AI processors can deliver acceptable throughput for edge applications like scene segmentation. Source: Ceva

Paths to exploit parallelism for AI inference

As in any parallelism problem, we start with a defined set of resources for our AI inference objective: some number of available accelerators with local L1 cache, shared L2 cache and a DDR interface, each with defined buffer sizes. The task is then to map the network graphs required by the application to that structure, optimizing total throughput and resource utilization.

One obvious strategy is in processing large input images which must be split into multiple tiles—partitioning by input map where each engine is allocated a tile. Here, multiple engines search the input map in parallel, looking for the same feature. Conversely you can partition by output map—the same tile is fed into multiple engines in parallel, and you use the same model but different weights to detect different features in the input image at the same time.

Parallelism within a neural net is commonly seen in subgraphs, as in the example below (Figure 2). Resource allocation will typically optimize breadth wise then depth wise, each time optimizing to the current step. Obviously that approach won’t necessarily find a global optimum on one pass, so the algorithm must allow for backtracking to explore improvements. In this example, three engines can deliver >230% of the performance that would be possible if only one engine were available.

Figure 2 Subgraphs highlight parallelism within a neural net. Source: Ceva

While some AI inference models or subgraphs may exhibit significant parallelism as in the graph above, others may display long threads of operations, which may not seem very parallelizable. However, they can still be pipelined, which can be beneficial when considering streaming operations through the network.

One example is layer-by-layer processing in a deep neural network (DNN). Simply organizing layer operations per image to minimize context switches per engine can boost throughput, while allowing the following pipeline operations to switch in later but still sooner than in purely sequential processing. Another good example is provided by transformer-based generative AI networks where alternation between attention and normalization steps allows for sequential recognition tasks to be pipelined.

Batch partitioning is another method, providing support for the same AI inference model running on multiple engines, each fed by a separate sensor. This might support multiple image sensors for a surveillance device. And finally, you can partition by having different engines run different models. This strategy is useful especially in sematic segmentation, say for autonomous driving where some engines might detect lane markings. Others might handle free (drivable) space segmentation, and some others might detect objects (pedestrians and other cars).

Architecture planning

There are plenty of options to optimize throughput and utilization but how do you decide how best to tune for your AI inference application needs? This architecture planning step must necessarily come before model compile and optimization. Here you want to explore tradeoffs between partitioning strategies.

For example, a subgraph with parallelism followed by a thread of operations might sometimes be best served simply by pipelining rather than a combination of parallelism and pipelining. Best options in each case will depend on the graph, buffer sizes, and latencies in context switching. Here, support for experimentation is critical to determining optimal implementations.

ISRO’s Aditya-L1 Reaches Destination, successfully placed in a halo orbit around L1 point

ELE Times - Mon, 01/08/2024 - 08:06

India’s maiden solar mission Aditya-L1 successfully reached its destination and was placed in a halo orbit around the L1 point on January 6, 2024.

The Indian Space Research Organisation (ISRO) launched the solar mission on September 2, 2023. The L1 point is located roughly 1.5 million km from Earth and will enable the spacecraft to view the sun continuously.

ISRO Chairman S Somnath told reporters that the halo orbit insertion process was done as intended. “Today’s event was to place the Aditya-L1 in the precise halo orbit. The spacecraft was moving towards the halo orbit but we had to make some corrections to put it in the right place. If we do not do the correction today there could have been a possibility that it could escape from this point (L-1 point). But we would not have allowed that to happen as there are some contingencies in place, but I am only telling mathematically it can escape.”

“So that has been very precisely done [placing the spacecraft in the halo orbit]. What we have achieved today is exact placement based on our measurement and very correct prediction of the velocity requirement. Right now, in our calculation the spacecraft is in the right place,” he added.

Latching relay question

Reddit:Electronics - Sun, 01/07/2024 - 16:05

Hi all, I'm new here. I'd appreciate your help with the following.

I have a latching relay module (the Adafruit one if it matters - 3V). It's meant to be used with their Feather MCU but it can also be used standalone (which is what I'm doing).

That relay has two separate trigger inputs for SET and RESET. I have a timer board with a single OUT wire that can automatically trigger a relay, an LED etc. after a set amount of time.

My question is, is it possible to trigger the relay on & off somehow (without an MCU) by having that single trigger voltage (e.g. 1 wire) alternate between the SET and RESET separate pins of the relay?

So effectively, pulse -> SET, pulse -> RESET, pulse -> SET, pulse -> RESET etc.

I hope I've explained this property. Any questions, let me know. Thank you.
