Mark all the correct statements about Complex Instruction Set Computer (CISC)
|
The instructions may use more than one word of memory
|
|
The instructions may represent complicated operations
|
|
The approach is more recent than RISC
|
|
Sequence of instructions are hard to pipeline
|
Explanation:
Detailed explanation-1: -Explanation: CISC is a computer architecture where in the processor performs more complex operations in one step.
Detailed explanation-2: -Characteristic of CISC – Instructions are larger than one-word size. Instruction may take more than a single clock cycle to get executed. Less number of general-purpose registers as operations get performed in memory itself. Complex Addressing Modes.
Detailed explanation-3: -A computer in which individual instructions may perform many operations and take many cycles to execute, in contrast with reduced instruction set computer (RISC).
