A microcomputer is based on the INTEL 8080 microprocessor which has 64 KB memory space. The microcomputer has 128 KB physical memory. Guess the technique that would be used by the microcomputer designer to double the memory supported by the microprocessor. Note that the 8080 does not support virtual memory.

A. Is IAS computer faster than Mark I computer? Is Mark I computer easy to program than IAS computer? B. The stack based CPUs don’t have registers for storing the operands. Can we conclude that the stack based CPU has less hardware circuits and hence cheaper than registers-based CPU? (Hint: stack control mechanism). C. Which

Intel 8086 and Intel 8088 are instruction set compatible microprocessors. The 8086 has 16-bit data bus whereas the 8088 has 8-bit data bus. The 8086 has 6-byte instruction (pre-fetch) queue whereas the 8088 has only 4-byte instruction queue. Do these two processors look alike to the software? In other words, do they have common architecture

A.A computer has floating-point arithmetic instructions. But the CPU hardware (datapath) does not have the floating-point ALU. How should the system handle floating-point arithmetic? B. In some computers, the floating-point ALU is self-contained and has no dependence on integer ALU. What are the advantages and disadvantages of such computers?
