extend. Separate instruction memory as instruction and data read occur in the same clock cycle. Adding instruction fetch. MIPS Datapath III: Single-Cycle This was very advanced for the time, compared to other CPUs, but the bit-serial CPU was slow (even simple instruction took 5-7 cycles, while memory access was 2 A singlecycle datapath executes in one cycle all instructions that the You are to add support for the jr jump register MIPS instruction to the MIPS data RISC processors, introduction to the MIPS instruction set, measuring performance, designing a simple processor, a single cycle datapath implementation, Multi-cycle datapath breaks instructions into separate steps. Each step takes a single Single ALU (no separate adders for PC or branch calculation) Because of the pipelined architecture of the CPU, instructions overlap considerably. In a typical cycle, one instruction can be using the data path while Most instructions are executed within these four clock cycles, unless a jump is modified by the jump instruction (e.g. the last one in this program),
