Click on the top “Embedded Miscellaneous” and “Star the Official Account” to view embedded notes at the first time! Everyone should have seen some videos of big shots grilling meat with computer CPUs. Is the temperature of the computer CPU really that high? Let’s take a look at what the temperature of our computer CPU … Read more
Embedded systems play a crucial role in our daily lives, covering areas from smartphones and cars to medical devices and industrial control systems. These systems must be designed with the utmost precision to ensure they operate reliably and safely. A key aspect of this design process is implementing comprehensive safety measures, such as CPU testing.In … Read more
Hello everyone, I am the Mixed Bag Master. Recently, a friend gave me a small board, and the MCU on the board is a very interesting thing – the parallel multithreading processor MC3172. In simple terms, this MCU internally implements functionalities similar to RTOS multithreading. However, the biggest difference between MC3172 programming and RTOS programming … Read more
1ćEmbedded Processor Basics A typical microprocessor consists of a control unit, program counter (PC), instruction register (IR), data channels, memory, etc. The instruction execution process is generally divided into: Fetch: Obtain the next instruction to be executed from memory into the instruction register; PC: Program Counter, always points to the next instruction to be executed; … Read more
This is the 78th original long article! A few days ago, I wrote a summary of embedded system hardware systems, discussing the components of hardware systems, as well as an overview of several units besides processors and storage. I do not plan to introduce these overviews in detail right now, as they are not very … Read more
CPU is an important part of digital processing systems. In my view, microcontrollers, microprocessors, and DSPs can all be referred to as CPUs, with their emphasis differing. Specifically, traditional microcontrollers are more focused on embedded computing, such as the commonly used 51, AVR, and ARM chips, which not only contain computational and control functions but … Read more
In December 2016, Vivienne Sze, Yu-Hsin Chen, and others (authors of Eyeriss) published a good review article titled “Hardware for Machine Learning: Challenges and Opportunities” on arXiv. Here, I would like to discuss my understanding of the “challenges” and “opportunities” in conjunction with this article [8] and the ISSCC2017 paper [1-7]. First, this discussion mainly … Read more
Recently, I watched a detailed explanation of circuit design by Philip Salmony, a graduate student from Cambridge University, on YouTube. The project is called the STM32-based RF to USB adapter, abbreviated as STRF, which includes: High-speed USB interface STM32L4 as the controller nRF24 2.4GHz RF transceiver Of course, he designed it using KiCad, and his … Read more
