HX1 Xilinx - Virtex-5 FXT Embedded Processor Block

This course covers the parameterizing of the Embedded Processor Block present in Virtex-5 FXT Xilinx FPGAs.

  • This course describes in depth the PPC440 core, including the optional FPU.
  • Differences between PPC440 and PPC405 are highlighted.
  • Practical labs provide CPU performance estimations through fixed-point and floating-point FFTs.
  • The course also details the operation of the internal crossbar connecting the PPC440, external PLB masters, LocalLink DMA channels to PLB slaves and memory.
  • The address decoding logic and arbitration mechanisms are explained through the EDK embedded processor block parameterizing wizard.
  • The LocalLink protocol is studied in order to clarify how data are transferred between hard LocalLink DMA channels and external soft IPs.
  • The course focuses on error recovery mechanisms that can be used during debug time to understand and fix bus errors.

  • This course has been designed by processor experts from Ac6, developing courses for IBM Microelectronics and AMCC for more than 10 years.
A more detailed course description is available on request at training@ac6-training.com
