Samsung patents chip feature that guesses data needs using a neural network
Samsung describes a method for computer chips to predict which data to load into fast memory before the processor asks for it. The system uses a small neural network to analyze patterns in the program's execution to make these guesses.
In the filing’s own words
An operating method of a computing system includes generating an inverted program counter by performing a bit inversion operation on a program counter, generating input data by performing an XOR operation based on a first address and the inverted program counter, performing a prefetch address prediction operation based on the input data by using a trained binary temporal convolutional neural network, and selectively performing data prefetch from a memory device to a cache memory based on a result of the prefetch address prediction operation, wherein the binary temporal convolutional neural network is trained based on a position delta map including an escape delta set and a proximity delta set.
What exactly they claim (claim 1)
1. An operating method of a computing system, the operating method comprising: generating an inverted program counter by performing a bit inversion operation on a program counter; generating input data by performing an XOR operation based on a first address and the inverted program counter; performing a prefetch address prediction operation based on the input data by using a trained binary temporal convolutional neural network; and selectively performing data prefetch from a memory device to a cache memory based on a result of the prefetch address prediction operation, wherein the binary temporal convolutional neural network is trained based on a position delta map including an escape delta set and a proximity delta set.
