System for reducing delay for execution subsequent to correctly predicted branch instruction using fetch information stored with each block of instructions in cache

摘要

A super-scaler processor is disclosed wherein branch-prediction information is provided within an instruction cache memory. Each instruction cache block stored in the instruction cache memory includes branch-prediction information fields in addition to instruction fields, which indicate the address of the instruction block's successor and information indicating the location of a branch instruction within the instruction block. Thus, the next cache block can be easily fetched without waiting on a decoder or execution unit to indicate the proper fetch action to be taken for correctly predicted branching.
