Simple cpu profile

Simple CPU profile

  • Application:

    • CPU core initiators with non-packet interface

    • Initiator read/write interface

  • Features:

    • Address mapped communication

    • 32 bit address

    • Natural data width, constrained block (burst) size

    • Byte enables

    • Bufferable to posted

    • Caching etc mapped to MReqInfo

    • Single-thread

    • Does not describe test extensions
