Systolic Arrays — Building the Heart of the TPU From Scratch
Piling on multipliers doesn't make a chip faster, because moving data costs more than the arithmetic does. This piece takes the grid at the center of the TPU — the systolic array — and shows exactly how it maps the triple loop of matrix multiplication onto rows, columns and clock ticks, from a 2×2 hand trace to a cycle-accurate simulator to the batch-size and shape rules you'll actually tune.

How AI Accelerators Are Designed — What Actually Separates GPUs, NPUs, and TPUs
GPUs, TPUs, and NPUs are three different answers to one question: how much generality do you trade away for matrix multiplication? A from-scratch tour of systolic arrays, dataflow design, and the co-evolution of hardware and quantization.
