First, we want to increment the shift counter, and perform the actual shift: when shifting => shift_counter := shift_counter + 1; s_out <= temp_reg (0); temp_reg <= s_in & temp_reg (n-1 downto 1); And then also detect when the shifting is done, in order to leave the shift state and go back to waiting:

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. phone app developer softwareWebCreate shift registers in your FPGA or ASIC.
