OpenAI patents chip design that flips math operations without moving data

This filing describes a hardware system where memory stores mathematical weights and nearby logic performs calculations. It uses switching circuits to change how data is grouped, allowing the same hardware to run a standard calculation or its flipped version without physically moving the stored data.

Why it mattersIt offers a specific way to make computer chips more efficient by reducing the need to move data around during complex math tasks.

In the filing’s own words

A system including a memory and hardware compute logic is described. The memory includes memory cells storing weights corresponding to a matrix. Hardware compute logic is coupled with the memory cells. The hardware compute logic is configured to perform a vector-matrix multiplication (VMM) for the matrix and for a matrix transpose for the weights being stationary for the memory cells.

What exactly they claim (claim 1)

1. A system, comprising: a memory storing a plurality of weights corresponding to a matrix; and compute logic coupled to the memory and configured to selectively perform a first vector-matrix multiplication (VMM) using the matrix and a second VMM using a transpose of the matrix, wherein the compute logic comprises: multiplication circuitry coupled to the memory, the multiplication circuitry configured to output results corresponding to multiplications of at least a portion of the plurality of weights and at least a portion of input vectors; a plurality of adder trees configured to accumulate the results; and selection logic comprising a plurality of input multiplexers configured to route elements of the input vector to the multiplication circuitry, wherein the selection logic is configured to: select a first portion of the plurality of adder trees and provide the results to the first portion in response to the compute logic performing the first VMM; and select a second portion of the plurality of adder trees and provide the results to the second portion in response to the compute logic performing the second VMM.
