Understanding the Complex Relationships Between MCU, ARM, DSP, FPGA, and Embedded Systems

Understanding the Complex Relationships Between MCU, ARM, DSP, FPGA, and Embedded Systems

First of all, “embedded” is a concept without a precise definition; different books have their own definitions. However, the main idea is similar: compared to general systems like PCs, embedded systems are specialized systems with a simplified structure, retaining only the necessary parts in both hardware and software while cutting out the unnecessary parts. Therefore, … Read more
