Methods and apparatuses for convolution of input data

A method for a convolution of input data and a weight matrix, comprising:

• obtaining, at an input register, an input vector of non-repeated data entries from an input data array;
• receiving, at a first input of an input mapping circuit from the input register, a first data entry of the input vector;
• selectively transmitting, within the input mapping circuit, the first data entry to a first output connected to a first weight register at a first compute unit, based on a control signal indicating a stride of the convolution;
• and
• performing a multiplication of the first data entry and a first weight corresponding to the first weight register for the convolution.

A system for a convolution of input data and a weight matrix, comprising:

• a memory storing a plurality of instructions;
• one or more hardware processors executing the plurality of instructions to perform operations comprising:
• obtaining, at an input register, an input vector of non-repeated data entries from an input data array;
• receiving, at a first pin of an input mapping circuit from the input register, a first data entry of the input vector;
• selectively transmitting, within the input mapping circuit, the first data entry to a first output connected to a first weight register at a first compute unit, based on a control signal indicating a stride of the convolution;
• and
• performing a multiplication of the first data entry and a first weight corresponding to the first weight register for the convolution.
