What is a pipeline? Pipeline is the shift register where computation actually occurs?
What is RISC? Reduced Instruction Set Computer. Instruction sets has different lengths. Shorter instruction sets are wasting the processing time. A RISC has built in decoder to arrange instructions to have equal length in order to reduce idling time. What is looping speculations? Computer did lots of iterations. These looping are very systematic and easily predictable. Smart processors can speculate them with 95% accuracy. If the prediction is wrong, the computer is smart enough to correct them. What determine the speed of my computer? Besides the CPU can affect the speed of your computer. The data bus system, access time of your hard drive, the buffer size, the amount and speed of memory, the configuration of your system, the operating system, the program itself, and many other factors can affect your speed. What is data bus system? Data bus is the channel in which data transfer between peripherals. Data could travel between CPU and the memory. Hard drive needs the bus to load data in
