Abstract
Disclosed is a system for improved instruction fetch prediction. When a jump instruction is encountered, the preceding instruction is considered in predicting the next instruction to fetch. If the preceding instruction is a skip instruction, the result of evaluating a condition specified by the skip instruction is used in predicting the next instruction to fetch. Prediction designators for skip/jump sequences of instructions are maintained in a jump prediction RAM.
