Given: A MIPS-based computer system with 2 GB of main memory that is built on a single circuit board. It is designed with a single control signal between the CPU chip and main memory, i.e. one bit of control that is set to one for Read operations and zero for Write operations.
a) How many bits wide is the main memory data bus?
b) How many bits wide is the main memory address bus when 4-banks memory interleaved is used?
c) How long does it takes to fetch 8 words from the memory to MIPS registers? Assume that one cycle is required to place the address and one cycle to transfer one word.
d) Find the memory bandwidth and compare it to memory bandwidth when no memory interleaved is used.
