The A68064 has a Harvard architecture, which means that it has separate buses for data and instructions. This allows for concurrent access to both data and instructions, improving overall system performance. The processor has a 32-bit address bus, which enables it to address up to 4 GB of memory.
The A68064 has a segmented memory organization, which divides the memory into 64 KB segments. Each segment can be configured as either code or data memory. The processor has a built-in memory management unit (MMU) that handles memory protection and address translation. a68064 datasheet
