PPT-Lecture 8 Pipelining: Datapath

and Control Pipelined datapath As with the singlecycle and multicycle implementations we will start by looking at the datapath for pipelining We already know that pipelining involves breaking up instructions into five stages. That can lead to either increasing the clock speed or decreasing the power consumption Multiprocessing can be also used to increase speed or reduce power brPage 2br YORK UNIVERSITY CSE4210 Pipelining ab yn xn2 xn1 xn tion multiplica one and additi 6 Nbits wide each Nmemory M words Random Access Memory RAM RAM Readable and writable memory Random access memory Strange name Created several decades ago to contrast with sequentiallyaccessed storage like tape drives Logically same as register file Mohammad . Sharifkhani. Motivation. All efficient low-power techniques that has been introduced depends on:. Technology enhancement. Specific Standard Cell Library. Analog Design Support. This means. and Control. Single-cycle implementation. As we’ve seen, single-cycle implementation, although easy to implement, could potentially be very inefficient. . In single-cycle, we define a clock cycle to be the length of time needed to execute a single instruction. So, our lower bound on the clock period is the length of the most-time consuming instruction. . Lecture 6: Superscalar Decode and Other . Pipelining. RISC ISA Format. This should be review…. Fixed-length. MIPS all insts are 32-bits/4 bytes. Few formats. MIPS has 3: R-, I-, J- formats. Alpha has 5: Operate, Op w/ Imm, Mem, Branch, FP. and Control. Single-cycle implementation.
