Abstract
A processor (e.g., a co-processor) comprising a decoder coupled to a pre-decoder, in which the decoder decodes a current instruction in parallel with the pre-decoder pre-decoding a subsequent instruction. In particular, the pre-decoder examines at least five Bytecodes in parallel with the decoder decoding a current instruction. The pre-decoder determines if a subsequent instruction contains a prefix. If a prefix is detected in at least one of the five Bytecodes, a program counter skips the prefix and changes the behavior of the decoder during the decoding of the subsequent instruction.
