... Architectural Overview 2.1 Description The ATR0625 architecture consists of two main buses, the Advanced System Bus (ASB) and the Advanced Peripheral Bus (APB). The ASB is designed for maximum performance. It inter- faces the processor with the on-chip 32-bit memories. The APB is designed for accesses to on-chip peripherals and is optimized for low power consumption ...
