Computer Arithmetic: From Fast Adders to Floating-Point
Arithmetic is the beating heart of every processor. Whether your machine is rendering 3-D graphics, training a neural network, or simply incrementing a loop counter, the ALU (Arithmetic Logic Unit) is doing the heavy lifting. In this deep-dive, I wan...
The Complete Memory Hierarchy: From Semiconductor RAM to Virtual Memory
The performance gap between processors and main memory has been widening for decades. Modern processors can execute billions of instructions per second, but accessing data from main memory takes hundreds of processor cycles. This disparity creates a ...
