Datapath: One Instruction Journey
Follow one instruction through fetch, decode, execute, memory, and writeback, see it match the Turing five phases, and watch a small program build a computation.
Above the sea of gates
By the previous chapters, switches became logic gates, and gates became addition. This chapter is their culmination. The blocks laid out before you — instruction memory, registers, the ALU, data memory — are all made from that sea of logic gates. And when a single instruction journeys across this sea, “computation” happens. First, advance just one beat and watch the instruction touch the first block.
Press “advance one beat” and watch the instruction begin to flow through the datapath.
