Abstract:
Techniques are disclosed for handling control transfer instructions in pipelined processors. Such instructions may cause the sequence of subsequent instructions to change, and thus may require subsequent instructions to be deleted from the processor's pipeline. Pre-decode means (110) are provided for at least partially decoding control transfer instructions early in the pipeline. Subsequent instructions can then be prevented from progressing through the pipeline. The mechanism required to delete unwanted instructions is thereby simplified.
