Wikipedia definition
2. Instruction prefetchIn computer architecture, instruction prefetch is a technique used in microprocessors to speed up the execution of a program by reducing wait states. Modern microprocessors are much faster than the memory where the program is kept, meaning that the program's instructions cannot be read fast enough to keep the microprocessor busy. Adding a cache can provide faster access to needed instructions.
