Turning a Raspberry Pi Pico into a GPU!

One enthusiast turned a Raspberry Pi Pico into a DVI graphics card, aiming for compatibility with various single-board computers, microcontrollers, and Linux modules. Inspired by existing projects, he created his own version, demonstrating the inventive spirit of DIYers and the flexibility of the Raspberry Pi platform. The project is open-source, with detailed steps available on GitHub. More information: The GitHub Youtube Video ...

Error Detection & Correction

There are many reasons such as noise, cross-talk etc., which may help data to get corrupted during transmission. The upper layers work on some generalized view of network architecture and are not aware of actual hardware data processing.Hence, the upper layers expect error-free transmission between the systems. Most of the applications would not function expectedly if they receive erroneous data. Applications such as voice and video may not be that affected and with some errors they may still function well. Data-link layer uses some error control mechanism to ensure that frames (data bit streams) are transmitted with certain level of accuracy. But to understand how errors is controlled, it is essential to know what types of errors may occur. Types of Errors...

STM32MP2 Microprocessors: Next-Gen Features Unveiled

STMicroelectronics has launched its latest STM32MP2 microprocessors featuring upgraded 64-bit Arm Cortex-A35 cores for enhanced performance in edge AI and machine learning tasks.

PICMG Releases InterEdge, New Standard for Process Control Systems

This is an interesting recent standard released by PICMG and I think as industrial systems are going further increasingly with distributed systems involving sensors, indicators and feedback systems, against the PLC type systems these modularization along with interoperability will add value. It is not very much thought about problem and the processes are adapted to the down-times. Eye catching part is that the modules are as hot-pluggable cradles and mechanical dimensions are standardised. https://embeddedcomputing.com/application/industrial/industrial-networking-connectivity/picmg-releases-interedge-new-standard-for-process-control-systems...

It's Altera again - a standalone FPGA company spinoff from Intel

Interesting to see their business plans upcoming in the embedded devices, automotive domains. This one caught me: "The goal of Gelsinger’s plan is to surpass Asian contract chip manufacturing giants TSMC and Samsung Electronics in process performance by 2025. At the same time, the company is hoping its revitalized contract chip-making business, Intel Foundry, will exceed Samsung’s foundry business in revenue by 2030" by doubling down the focus in Intel alone. https://www.crn.com/news/components-peripherals/2024/intel-brings-back-altera-as-standalone-fpga-company...
