FPQA MPC837XE implementation

This course covers PowerQUICC II Pro MPC837XE


Objectives
	The course focuses on the internal interconnect architecture, based on the CSB 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 MPC837X.
	A long introduction to DDR SDRAM operation is done before studying the DDR2 SDRAM controller.
	An in-depth description of the PCI controller is performed.
	The course highlights both hardware and software implementation of gigabit / fast / Ethernet controllers and the parameterizing of the level 2, 3 and 4 acceleration mechanisms.
	The USB interface is also detailed.
	The course explains how to initialise both the Serdes block and the SATA controller to detect and communicate with an external hard disk.
	Generation of a Linux image and Root File System by using LTIB can also be included into the training.
	This course has been delivered several times to companies developing telecom infrastructure equipments.
A lot of programming examples have been developed by ACSYS to explain the boot sequence and the operation of complex peripherals, such as SATA and Ethernet. •They have been developed with Diab Data compiler and are executed under Lauterbach debugger.
