Q

What are the advantages of CISC?(4)

A

Requires little RAM to store code(1) Compiler does little work to convert code to machine code as the code is very short(1)As it has a large amount of instructions.(1) In assembly for CISC the statement only takes one mnemonic(1).

Q

What are the disadvantages of CISC?(3)

A

CISC processors have complex components(1) therefore it is more expensive to make(1).Also for CISC processors have a varied instruction time , as it takes one clock-cyle for each instruction (1).

Q

What are the advantages of RISC?(3)

A

RISC Processors have simple parts(1) therefore are cheaper to manufacture(1). As RISC consist of simpe commands they take ths same time to execute, therefore it runs programs quickly (1).

Q

What are the disadvantages of RiSC?(3)

A

RISC Processors require multiple instructions for complex tasks (1) . It require several instruction for complex tasks so More RAM space required. When translating to machine code compiler needs to do more work to connvert langauge due to it having multiple mnuemonics (1).

Q

What is the difference between Parallel and Multicore processing? (2)

A

Parallel processing is when the instructions are not broken up and processed in one go (1). While Multicore processors breaks the instrustions into Fetch/Decode/Execute and each core does one of the F/D/E cycle.
