Principle Computer Architecture

A computer system needs 256 bytes of RAM, 1024 x 16 of ROM and two I/O interface modules with 256 registers each with each register size is 8-bits. Build the memory system of the new computer using a 128 x 8 RAM and 512 x 8 ROM. 1. Compute the total number of bits required to address the memory system. 2. Design the memory-address map for the above system.
