WGU C952: Computer Architecture Questions and Answers Already Passed

Document Content and Description Below

Main memory ✔✔also known as "primary memory" typically consists of DRAM Secondary memory ✔✔ex: hard disk drive Branch prediction ✔✔A way to resolve a branch hazard by seeing if the branc ... h was taken last time it was encountered. The result is stored in the branch prediction buffer (aka branch history table) reservation station ✔✔one primary unit within dynamic scheduling that holds the operands and the operation within a functional unit (see pic) commit unit ✔✔The unit in a dynamic or out-of-order execution pipeline that decides when it is safe to release the result of an operation to programmer-visible registers and memory. (see pic) dynamic pipeline scheduling ✔✔Hardware support for reordering the order of instruction execution so as to avoid stalls. frame buffering ✔✔The process of storing the image to be represented onscreen before it is read out to the graphics display (see pic) SIMD ✔✔single instruction stream, multiple data streams: The same instruction is applied to many data streams, as in a vector processor. MIMD ✔✔multiple instruction streams, multiple data streams: A multiprocessor. SPMD ✔✔single program, multiple data streams: The conventional MIMD programming model, where a single program runs across all processors [Show More]
