What is RISC?
RISC- Reduced Instruction Set Computer
What is an Instruction Set?
An instruction set lists commands a CPU understands and performs different operations
Ok coming back to RISC, it is a type of computer architecture that uses a small, optimized set of instructions, as opposed to Complex Instruction Set Computing (CISC) architectures, which have a larger instruction set
Oh, what is a pipeline architecture? Here you go?
Consider a pipe with many insertion points for a typical fluid flow. On these points, the CPU operates the instructions e.g. Instruction Fetch (IF): The CPU fetches the next instruction from memory; Instruction Decode (ID): The fetched instruction is decoded to determine what operation it specifies, and the relevant data (operands) are fetched from registers; Execute (EX): The actual operation is performed; Memory Access (MEM): If the instruction requires accessing memory (for load or store operations), this stage handles that data transfer; Write Back (WB): The result of the execution (if applicable) is written back to the register file. By allowing multiple instructions to be in different stages of execution at the same time, the CPU can complete more instructions with fewer cycles
RISC for MAC implementation?
What is MAC
The MAC operation typically involves multiplying two numbers and then adding the result to an accumulated value

Where are MACs used?
In ML, neural networks, where every node has a typical set of numbers associated with it, and these numbers across all the nodes are consistently updated after multiplication and addition cycles
RISC Ecosystem
Are RISC processors ready to take off (or took off already) for data center use cases?
Indeed, RISC processors took off for data center use cases, driven by their performance capabilities, energy efficiency, scalability, and increasing support from the software ecosystem. With significant adoption by cloud service providers and specialized hardware manufacturers, RISC architectures are proving to be a competitive option for various data center workloads. As technology and implementations continue to evolve, RISC processors are likely to play an increasingly important role in the future of data center computing
