When it comes to the design and energy efficiency of processors, if we talk about the most classic RISC processor, then it must be MIPS. Even its competitors have to acknowledge its elegance. It is regarded as a model in processor textbooks, and many other processors bear its influence. Next, let’s explore the origins of … Read more
The acceleration of DSP in Cortex-M core microcontrollers is entirely achieved through these instructions, and I will introduce how the DSP source code implements this acceleration.

Recently, foreign media reported that MIPS Technologies announced it would abandon the design of the MIPS instruction set and shift to RISC-V. In response, Tieliu couldn’t help but sigh, “Forty years east of the river, forty years west of the river“. MIPS, as the first commercially available RISC instruction set, has been abandoned by the … Read more
RISC-V and ARM are both processor architectures based on the RISC (Reduced Instruction Set Computer) principle, but they have significant differences in design philosophy, business models, openness, ecosystems, and application scenarios. Here are the main differences between the two: 1. Architecture Openness RISC-V Open Source Instruction Set Architecture (ISA): The instruction set specification of RISC-V … Read more

Instruction Overview Instructions: Commands executed by the CPU based on human intention to perform certain operations. Instruction System: The set of all instructions that a computer can execute. Program: A sequence of instruction operations compiled according to human requirements. This … Read more
RISC-V is also known as “the Linux of CPUs.” For some, this title feels like a legacy and an innovation at the same time, especially if you are a staunch believer in open source. However, I am a true pragmatist, and the excessive marketing of RISC-V has made me lose interest in the term. It … Read more
| Source: SIMIT Strategic Research Office (ID: SIMITSRO) Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences The two major architectures of current CPUs are CISC (Complex Instruction Set) and RISC (Reduced Instruction Set). x86 is the representative architecture of CISC, occupying over 95% of the desktop computer and server market. Arm, as … Read more
This article is reprinted from the Extreme Community Extreme Column: Agile MM32 MCU Author:Nuoeriris The Arm processor is designed based on the principles of Reduced Instruction Set Computing (RISC). The instruction set and associated decoding mechanisms are relatively simple, featuring a 32-bit Arm instruction set and a 16-bit Thumb instruction set. The Arm instruction set … Read more
