M4	440EPx implementation

This course covers AMCC 440EP and 440EPx processors

Objectives The course explains how to design a 440EPx board. DDR SDRAM operation is described in order to understand both the electrical interface and the memory controller programming. Book E PowerPC architecture is studied through the 440EPx, especially the MMU. The training focuses on the new floating point unit. The course provides examples of internal peripherals software drivers. Gigabit Ethernet controller is viewed in detail. The training describes on data flows between PCI bus and internal PLB bus. A chapter on Linux porting can be appended on request. Labs are compiled with Diab Data compiler and run under Lauterbach debugger. A more detailed course description is available on request at info@ac6-formation.com

Prerequisites Experience of a 32 bit processor or DSP is mandatory. Knowledge of PCI bus is recommended (see our course reference I1). Knowledge of USB is recommended (see our course reference I6).

THE SECURITY MODULE Introduction to encryption On-chip Ipsec / SSL Security acceleration engine Public key acceleration
