Objectives
  • The course clarifies the architecture of the P20X0, particularly the operation of the coherency module that interconnects the e500s to memory and high-speed interfaces.
  • Cache coherency protocol is introduced in increasing depth.
  • The e500 core is viewed in detail, especially the SPE unit that enable vector processing.
  • The boot sequence and the clocking are explained.
  • The course focuses on the hardware implementation of the P20X0.
  • A long introduction to DDR SDRAM operation is done before studying the DDR2/3 SDRAM controller.
  • An in-depth description of the RapidIO port and the PCI-Express port is done.
  • The course explains how to implement QoS on GigaEthernet controllers.

  • ACSYS has developed an optimized SPE based FFT coded in assembler language.
  • Performance for 1024 complex floating point single precision samples is:
    • - 91_386 core clock cycles without reverse ordering, 94_124 with reverse ordering
  • Performance for 4096 complex floating point single precision samples is:
    • - 470_778 core clock cycles without reverse ordering, 511_227 with reverse ordering
