Low power design of CMOS circuit based on linear feedback shift register

introduction As portable devices and wireless communication systems are more and more widely used in real life, The power consumption of design for testability (DFT) has attracted more and more attention of VLSI designers. Because the power consumption of the circuit in test mode is much higher than that in normal mode, it will bring […]

Function and usage analysis of internal register of 51 single chip microcomputer

1. Warning 280:’i’:unreferencedLOCal variable Note that the local variable I does not make any access operation in the function. The solution is to eliminate the declaration of variable I in the function 2 Warning 206:’MusIC3’:missing function-prototype Note music3() function is not declared or externally declared, so it cannot be called to other functions The solution […]

Is the register in 8051 single chip microcomputer CPU or ram

Question: are some registers in MCU 8051 CPU or ram? Please point out that some registers such as accumulator dptr, a and PSW belong to the CPU, but the book says that they all belong to the special function register (SFR) in RAM. What’s the reason? In addition, aren’t memory and register two things with […]
