Question

Which characteristics of RISC systems could be directly implemented in CISC systems? Which characteristics of RISC machines could not be implemented in CISC machines (based on the defining characteristics of both architectures as listed in the Table)?

RISC CISC Single register set, typically 6 to 16 registers total Multiple register sets, often consisting of more than 256 registers One or two register operands allowed per instruction (e.g., add R1, R2) Three register operands allowed per instruction (e.g., add R1, R2, R3) Parameter passing through inefficient off-chip memory Parameter passing through efficient on-chip register windows Single-cycle instructions (except for load and store) Hardwired control Highly pipelined Simple instructions that are few Less pipelined Many complex instructions in number Complexity in compiler Complexity in microcode Only load and store instructions canMany instructions can access accesS Few addressing modes Many addressing modes ABLE 9.1 The Characteristics of RISC Machines versus CISC Machines

Explanation / Answer

characteristics of RISC systems could be directly implemented in CISC Systems:-

Three register operands, Highly pipelined, fixed-lenth instructions, hardwired control, a small number of simple instructions, complexity in compiler, and allowing few addressing modes could be implemented in CISC.

characteristics of RISC systems could not be directly implemented in CISC Machines:-
