CISC vs RISC

---

There are two different ways of designing computer processors:

• CISC (Complex Instruction Set Architecture) uses a large set of complex, multi-step instructions, aiming to do more work per instruction, common in PCs (x86) by Intel/AMD.
• RISC (Reduced Instruction Set Architecture) uses a small, simple, highly optimized set of instructions for faster execution and better energy efficiency.

The differences between CISC and RISC include:

• RISC uses a small set of simple, fixed-size instructions designed to execute in a single clock cycle.
• CISC includes a larger set of instructions, many of which are complex and can perform multiple operations (e.g., memory access and computation) in a single instruction.
• CISC instructions often require multiple clock cycles.

Review: CISC (Complex Instruction Set Computing)

Which statement is NOT true about CISC (Complex Instruction Set Computing)?   A CISC instruction can manipulate memory directly.   ARM remains the industry standard for malware analysis.   CISC instructions often require multiple clock cycles.   Many CISC instructions can perform multiple operations in a single instruction.
