Bus Interface Unit
1. Features
The SCP’s bus interface unit (BIU) manages address space and outputs control signals that enable
optimal memory access. This allows ROM, SRAM, DRAM and other general devices to be accessed.
2. Address Space
The address space that can be directly accessed by load/store instructions is 4 gigabytes. The BIU
manages this address space by dividing it into several.
