VHDL Code for 4- Bit Shift Register. VHDL Code for shift register can be categorised in serial in serial out shift register, serial in parallel out shift register, parallel in parallel out shift register and parallel in serial out shift register. Parallel In ā Parallel Out Shift Registers. For parallel in ā parallel out shift registers, all data bits appear on the parallel outputs immediately following the simultaneous. The following circuit is a four- bit parallel in ā parallel out shift register constructed by D flip- flops. The Dās are. Once the register is clocked, all the data at the D inputs appear at the corresponding Q outputs simultaneously. The following circuit is a four- bit Serial.
