Overview of Embedded Systems //From Hardware Perspective：“Embedded” integrates peripheral devices based on the CPU into the CPU chip itself. For example, early computers based on the X86 architecture had CPUs that only performed computation and accumulation functions. All chips needed external bridges to expand functionality, such as serial ports that relied on external 16C550/2 serial … Read more
