RISC (Reduced Instruction Set Computer) is a type of microprocessor architecture commonly used in modern CPUs. Unlike CISC (Complex Instruction Set Computer), which relies on a large and complex set of instructions, RISC focuses on simpler instructions that can be executed more quickly. This streamlined design enables faster data transactions and supports parallel processing, allowing CPUs to handle multiple operations efficiently.
In this guide, we will explore:
- What is an RISC?
- Its working principle and main components are used in this microprocessor.
- It's a block diagram and a method to create such beneficial block diagrams.
In the end, you will be able to learn how to create these block diagrams with ease and learn the basics of these microprocessors.

Block Diagram of RISC
RISC block diagram breaks down the complex circuitry of these microprocessors. It helps you learn about the basic components and how they work.
Let's check out the block diagram of RISC.
Working Principle of an RISC
RISCs are specialized microprocessors used to perform smaller operations in one cycle only. They are used to support the CPU, helping it to perform better and offer maximum speeds. Here are the key principles to consider when breaking down the overall workings of an RISC.
Reduced Instruction Set
The instruction set in RISC is programmed to perform a single transaction or calculation at a time, offering maximum speed. Each set operates in parallel operations and performs one activity, like moving the data or managing a calculation.
No Arithmetic and Logical Operations
The instructions in RISC don't help perform any logical or Arithmetic operations. Only load and store instructions are allowed to access the memory in the RISC. The register files are responsible for Arithmetic and Logical operations.
Execution of Data through a Single Cycle
The speed of the processor is dependent on the single-cycle executions in RISC. Most of the instructions are operated through single cycles, improving the speed of the CPU. This is what CISC lacks, as it performs multiple tasks in multiple cycles, causing a delayed response.
Register Files
The register files are large in the RISC system. They are responsible for most of the operations, neglecting access to the main memory in RISC systems. The information is operands and retrieved from these registers.
Hardwired Operation
A Simple hardwired logic is used to respond to the instructions, making the overall process faster. It happens due to the instruction sets, as it doesn't require microcode to make complex calculations. Their operations are prone to provide maximum efficiency and programmed to change their operation when needed.
Applications of an RISC
Here are a few of the applications of the RISC microprocessors.
Smartphones
Most of the ARM architecture uses RISC-based microprocessors to speed up mobile device operations due to their fixed instructions. The low power consumption of these RISC processors helps smartphones extend their battery life.
Embedded Systems
RISC-based processors are the best for embedded systems in the automotive industry, home appliances, and industrial machinery. These embedded systems require single tasks readily, and RISC provides maximum efficiency using the minimum resources, which saves a lot of power.
Networking and Telecommunication
RISC microprocessors were first created for networking and telecommunications devices. The reduced instructions and latency make these devices ideal for routers, modems, and modern communication infrastructures.
Educational and Research Purposes
The RISC microprocessors offer simplicity and are good for educational and Research Purposes. Students use these processes to learn different things about instruction sets, compilers, and operating systems. This helps create an environment for the researcher and improves the computing systems as well.
