How about a cheap serial terminal for less than a fiver all-in? In a previous blog entry I’ve been working on more developments for the increasingly powerful home control system using an Arduino as a kind of universal I2c peripheral to the ESP8266. The reason for that is just the vast range of driver software […]

Researchers want to give a 25-core open-source processor called Piton some serious bite. The developers of the chip at Princeton University have in mind a 200,000-core computer crammed with 8,000 64-bit Piton chips. It won’t happen anytime soon, but that’s one possible usage scenario for Piton. The chip is designed to be flexible and quickly
Open source 25-core processor can be stringed into a 200,000-core computer Continue Reading
A microchip containing 1,000 independent programmable processors has been designed by a team at the University of California, Davis, Department of Electrical and Computer Engineering. The energy-efficient “KiloCore” chip has a maximum computation rate of 1.78 trillion instructions per second and contains 621 million transistors. The KiloCore was presented at the 2016 Symposium on VLSI

Despite its popularity among hobbyists and electronics enthusiasts, the Arduino has become infamous among professional embedded systems developers. I must admit that for the longest time I also viewed the Arduino as so simple it was nearly useless for professional developers. But I have changed my mind. I’ve found that on a number of occasions
Prototype to production: Arduino for the professional Continue Reading
I’ve been thinking about building stuff with FPGA’s for a while, and usually get turned away because FPGA’s are considerably harder to implement than microcontrollers since they have no on-chip memory. It is necessary to re-program the gates every time they power up, which requires an external flash memory chip. There aren’t great references online

Established companies and emerging start-ups are putting a stake in the Internet of Things ground, an opportunity with estimates of 50 billion devices connected by 2020. Standing in the way for many companies is the increasing complexity of technology inside connected devices. Shortened design cycles further fuel pressure felt by designers — the shelf-life of an IoT

How can you count bits in hardware? In this article, I reverse-engineer the circuit used by the ARM1 processor to count the number of set bits in a 16-bit field, showing how individual transistors form multiplexers, which are combined into adders, and finally form the bit counter. The ARM1 is the ancestor of the processor

Nandland Go Board – Your FPGA Playground My name is Russell and I am the creator of www.nandland.com. I started Nandland to increase the usage of FPGAs by making them easy to use. I am thrilled to announce after months of hard work the creation of the next phase of that plan: The first FPGA

ESP32 is the hottest new wireless chip out there, offering both WiFi and Bluetooth Low Energy radios rolled up with a dual-core 32-bit processor and packed with peripherals of every kind. We got some review sample dev boards, Adafruit and Seeed Studio had them in stock for a while, and AI-Thinker — the company that

ARM has introduced its highest performance Cortex-M series processor core. The Cortex-M7 retains the same instruction set of the other processors in the Cortex M series, but has been given a six-stage super scalar pipeline architecture which dramatically increases its performance over the previous Cortex-M4. Ian Johnson, product manager at ARM told Electronics Weekly, the
