State Diagram Alu State transition diagram Control Logic Description File The control logic of the ALU is implemented using a script called platool to build a magic file from a text file (called a meg file). The meg file contains a description of the finite state machine that should be implemented by the resulting PLA.
State Diagram Alu Why a Multiple Cycle CPU? • The problem => single-cycle cpu has a cycle time long enough to complete the longest instruction in the machine • The solution => break up execution into smaller tasks, each task taking a
State Diagram Alu The state diagram of the Moore FSM for the sequence detector is shown in the following figure. Last time , an Arithmetic Logic Unit ( ALU ) is designed and implemented in VHDL . Full VHDL code for the ALU was presented.
