3.0 SYSTEM OVERVIEW
Three main blocks can be identified in the device architecture: ARM domain, the D950 domain and the
Clocks tree domain.
3.1 ARM7 domain
The ARM domain is a multibus microprocessor system based on the ARM7TDMI processor.
The system bus is based on the Advanced Microcontroller Bus Architecture (AMBA) that includes
two distinct buses:
The Advanced High performance Bus (AHB) for high performances system modules
The Advanced Peripheral Bus (APB) for low power peripherals.
A high speed 32 bit data bus is provided to connect external memories.
A controller for external static memory (ESM) and a controller for external dynamic memory (EDM)
are provided.
Static memories, like FLASH EPROM, SRAM and dynamic memories like EDO, SDRAM, can be
