FCQ11	P102X QorIQ implementation

This course covers Freescale QorIQ P101X and P102X QorIQ SoC family

Objectives The course clarifies the architecture of the P102X, 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 P102X. A long introduction to DDR SDRAM operation is done before studying the DDR2/3 SDRAM controller. An in-depth description of the PCI-Express port is done. The course highlights both hardware and software implementation of gigabit / fast / Ethernet controllers. Management of E1/T1 lines by QUICC engine is explained. 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 guillaume.peron@ac6.fr A more detailed course description is available on request at info@ac6-training.com
