Understanding the Roles of CPU, NPU, GPU, and DSP in Embedded Systems

1. CPU (Central Processing Unit) Meaning:The core computation and control unit of a computer, equivalent to the “brain commander.” Function:Responsible for executing computer instructions, coordinating all hardware, and handling general computing tasks, with both computation and control capabilities. Main Applications:The fundamental computations of all computing devices (computers, smartphones, servers, etc.), such as system booting, software … Read more

How to Calculate MIPS Data

MIPS stands for Million Instructions Per Second, which indicates the number of millions of instructions executed per second. Most DSPs belong to the RISC type, which means they have a small instruction set, with the majority being single-cycle instructions. Only a few instructions, such as jumps and function calls, require multiple cycles to execute. Therefore, … Read more
