- Explain the difference between Harvard and von Neumann architectures in the context of microcontrollers.2. Design a 32x38 memory subsystem with high-order interleaving assuming 16x2 memory chips for a computer system with an 8-bit address busLet us assume that we would like to design an ISA R-format instruction format for a processor. The processor has 256 registers and 64 opcodes. The R-format has four fields, the opcode and three fields for the registers. Show the instruction format and the bit allocation for each field.
- The usage of the RISC and CISC architectures in computer applications should be explained and demonstrated. Coding for fundamental memory locations and addressing operations, as well as timing graphs, should be recorded in Assembler language.Consider the instruction ADD R1, M (R1 = R1 + [M]). M is the memory address of the operand. It is a two-word instruction – first word is the op-code and the second word is the address of the operand. Give the RTL description for the complete execution (including fetch phase) of the instruction.A RISC instruction pipeline has five stages with propagation delays of 20 ns, 25 ns, 20ns, 70 ns, and 40 ns, respectively. What is the clock period? If a non-pipelined CPU can process an instruction in 160 ns, what is the actual steady-state speedup of the pipeline?
