Abstract

Techniques are disclosed relating to instruction set architecture support for matrix manipulations. In disclosed embodiments, front-end circuitry is configured to fetch and decode a matrix multiply instruction for execution, including to encode a given matrix input operand of the matrix multiply instruction to identify one or more vector registers defined according to an instruction set architecture. In some embodiments, datapath circuitry is configured to execute the matrix multiply instruction, where during execution of the instruction, the one or more vector registers corresponding to the given matrix operand are mapped within the datapath circuitry to at least two dimensions of the given matrix operand. In some embodiments, power management circuitry is configured to, during execution of the instruction, operate at least a portion of the front-end circuitry in a reduced-power mode. Disclosed techniques may advantageously increase throughput and reduce power consumption, relative to traditional implementations using vector operations.
