Reducing Noise Issues In Microcontroller Systems: Part 1
By Graeme Clark - 22 Jun, 2023 - Comments: 0

In my ideal digital world, of which I often dream, signal voltage margins are always positive, signal timing margins are always positive, power supply voltages are always within the operating voltage range, and our environment is completely benign. Unfortunately, none of us live in this ideal world, no matter how much I would like to. The real world is dirty and noisy, and the power distribu... » read more

Training a ML model On An Intelligent Edge Device Using Less Than 256KB Memory
By Technical Paper Link - 11 Oct, 2022 - Comments: 0

A new technical paper titled "On-Device Training Under 256KB Memory" was published by researchers at MIT and MIT-IBM Watson AI Lab. “Our study enables IoT devices to not only perform inference but also continuously update the AI models to newly collected data, paving the way for lifelong on-device learning. The low resource utilization makes deep learning more accessible and can have a bro... » read more

Integrate FPGAs For A Customizable MCU
By Andy Jaros - 05 Aug, 2021 - Comments: 0

MCUs come in a broad range of flavors, meaning you can pick the best one for the application with the right performance, feature set, peripherals, memory, and software programmability. So, then, why do many systems also use FPGAs next to the MCUs? Usually, it’s because there’s not a “perfect” MCU for their application. MCUs by definition are built to be generic for a wide variety of app... » read more

MPU Vs. MCU
By Bryon Moyer - 01 Dec, 2020 - Comments: 1

There was a time when microprocessors and microcontrollers were distinct devices. There was never a question as to which one you were dealing with. But changes in the memory architecture have muddied the distinction in modern devices. There are a number of ways in which microprocessors and microcontrollers could possibly be differentiated. But there is no universal agreement as to how that s... » read more

What Happened To Execute-in-Place?
By Bryon Moyer - 25 Aug, 2020 - Comments: 0

Executing code directly from non-volatile memory, where it is stored, greatly simplifies compute architectures — especially for simple embedded devices like microcontrollers (MCUs). However, the divergence of memory and logic processes has made that nearly impossible today. The term “execute-in-place,” or ”XIP,” originated with the embedded NOR memory in MCUs that made XIP viable. ... » read more

Week In Review: Design, Low Power
By Ed Sperling - 14 Feb, 2020 - Comments: 0

Processors Arm rolled out a micro neural processing unit that, when combined with its newest microcontroller, can increase machine learning performance by up to 480 times. The company is aiming the MCU and co-processor across a wide swath of applications. Worth noting is that Arm calls its Cortex-M55 an AI-capable processor, rather than a microcontroller, as the lines between the various proce... » read more

Week In Review: Design, Low Power
By Jesse Allen - 16 Aug, 2019 - Comments: 0

Everspin and Seagate inked a patent cross-licensing agreement, including the assignment and licensing of MRAM patents from Seagate to Everspin as well as licensing of specific Tunneling Magnetoresistance (TMR) patents from Everspin to Seagate, which will be used in HDD read/write head technology. Subaru utilized ANSYS' SCADE suite for critical control systems to design and validate embedded ... » read more
