How to implement a shift register in VHDL - Surf-VHDL

WebShift-Register. The main usage for a shift register is for converting from a serial data input stream to a parallel data output or vice versa. For a serial to parallel data conversion, the bits are shifted into the register at each clock cycle, and when all the bits (usually eight bits) are shifted in, the 8-bit register can be read to produce the eight bit parallel output. WebIn computer science, a logical shift is a bitwise operation that shifts all the bits of its operand. The two base variants are the logical left shift and the logical right shift. This is further modulated by the number of bit positions a given value shall be shifted, such as shift left by 1 or shift right by n. share screen macbook
