FN5	MPC834X implementation

This course covers PowerQUICC II Pro MPC834X processors, such as MPC8349A

Objectives The course focuses on the sequencer that interconnects e300, DDR SDRAM, PCI and external bus. Cache coherency protocol is introduced in increasing depth. The 32-bit e300 core is viewed in detail, especially the MMU and the cache. The boot sequence and the clocking are explained. The course focuses on hardware implementation of the MPC834X. A long introduction to DDR SDRAM operation is done before studying the DDR SDRAM controller. An in-depth description of the PCI controllers is performed. The course highlights both hardware and software implementation of gigabit / fast / Ethernet controllers. The USB interfaces are also detailed. This course has been delivered several times to companies developing avionics equipments. A lot of programming examples have been developed by ACSYS to explain the boot sequence and the operation of complex peripherals, such as USB and Ethernet.   •They have been developed with Diab Data compiler and are executed under Lauterbach debugger. A more detailed course description is available on request at info@ac6-training.com

Prerequisites
	Experience of a 32 bit processor or DSP is mandatory.
	Knowledge of USB is recommended, see our course reference I6.
	Knowledge of PCI is recommended, see our course reference I1.
	Knowledge of Ethernet is recommended, see our course reference N1.
