This course covers PowerQUICC III MPC854X devices, including MPC8548E

Objectives The course details the internal data path, particularly the Ocean crossbar operation. Cache coherency protocol is introduced in increasing depth and the benefit of data stashing is explained. The e500 core is viewed in detail, especially the SPU that enables Floating point and vector processing. The boot sequence and clocking are explained. The course details the hardware implementation of the MPC854X. A long introduction to DDR1/2 SDRAM operation is done before studying the DDR SDRAM controller. An in-depth description of the RapidIO port and the PCI-X port is done. The PCI Express bridge implemented in the MPC8548E is also described. The course highlights both hardware and software implementation of gigabit / fast / Ethernet controllers, particularly the TCP/IP hardware assistance engine. 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 for any information contact formation@ac6-formation.com A lot of programming examples have been developed by ACSYS to explain the boot sequence and the operation of complex peripherals, such as GigaEthernet. •  They have been developed with Diab Data compiler and are executed with Trace32 Lauterbach debugger. A more detailed course description is available on request at formation@ac6-formation.com
