PPT-Pipelining

Two forms of pipelining Instruction unit overlap fetchexecute cycle so that multiple instructions are being processed at the same time each instruction in a different portion of the fetchexecute cycle. 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 2 w1w2w3w4w1w2w3w4g1 (high byte)g2 (low byte)FFFFg5 (high byte)g6 (low byte)G (1 to 32)ABAB Figure 1.
