CISC and RISC processors

Complex instructions are built directly into the hardware

• CISC

• RISC

• BIOS

• ROB :D

Answer explanation

CISC (Complex Instruction Set Computing) architectures are designed to execute complex instructions directly in hardware, allowing for more powerful operations per instruction compared to RISC (Reduced Instruction Set Computing), which uses simpler instructions.

Compiler has to do more work to convert high-level-language (VB, Python, C#) statements into instruction code.

• CISC

• RISC

• BIOS

• ROB :D

Answer explanation

RISC (Reduced Instruction Set Computer) architectures require more work from the compiler to translate high-level language statements into machine code, as they use a smaller set of simpler instructions compared to CISC (Complex Instruction Set Computer).

The primary goal is to complete the task using as few lines of code as possible.

• CISC

• RISC

• BIOS

• ROM

Answer explanation

CISC (Complex Instruction Set Computing) aims to reduce the number of lines of code by using complex instructions that can perform multiple operations. This makes it suitable for tasks requiring fewer lines of code compared to RISC.

Instruction is executed within one clock cycle.

• CISC

• RISC

• BIOS

• ROM

Answer explanation

RISC (Reduced Instruction Set Computer) architecture is designed for high performance by executing instructions in a single clock cycle, unlike CISC (Complex Instruction Set Computer) which may take multiple cycles.

Processor hardware is capable of understanding and executing a series of operations in one instruction.

• CISC

• RISC

• BIOS

• ROM

Answer explanation

CISC (Complex Instruction Set Computing) processors can execute multiple operations in a single instruction, making them capable of understanding complex commands, unlike RISC (Reduced Instruction Set Computing) which focuses on simpler instructions.

Load and store instructions need to be explicitly stated in the program.

• CISC

• RISC

• BIOS

• ROM

Answer explanation

RISC (Reduced Instruction Set Computer) architectures require explicit load and store instructions in programs, contrasting with CISC (Complex Instruction Set Computer) which has more complex instructions that can handle memory operations directly.

More RAM is needed to store instructions.

• CISC

• RISC

• BIOS

• ROM

Answer explanation

RISC (Reduced Instruction Set Computer) architectures require more RAM to store instructions due to their use of a larger number of simpler instructions, which can lead to increased instruction count compared to CISC (Complex Instruction Set Computer).

Explicit loading and storing instructions are not necessary.

• CISC

• RISC

• BIOS

• ROM

Answer explanation

CISC (Complex Instruction Set Computing) architectures allow for more complex instructions that can perform multiple operations, making explicit loading and storing instructions unnecessary, unlike RISC (Reduced Instruction Set Computing) which requires them.

Instruction code closely resembles commands in a high-level language.

• CISC

• RISC

• BIOS

• ROM

Answer explanation

CISC (Complex Instruction Set Computing) uses a rich set of instructions that closely resemble high-level language commands, making it easier for programmers to write complex operations in fewer lines of code compared to RISC.

Less transistors are required.

• CISC

• RISC

• BIOS

• ROM

Answer explanation

RISC (Reduced Instruction Set Computer) architectures use fewer transistors compared to CISC (Complex Instruction Set Computer) designs. This simplicity allows for faster processing and lower power consumption, making RISC the correct choice.
