In the world of smartphone chips, such as Kirin, Qualcomm, MediaTek, and Apple’s, they are all competing for single-digit nanometer processes to achieve the highest efficiency and advanced instruction sets for maximum performance release. However, in the industrial field, if you casually open a PLC, you will find that the main control CPU on the … Read more
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
1、Embedded 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
