The present disclosure is directed to systems and methods of performing one or more broadcast or reduction operations using direct memory access (DMA) control circuitry. The DMA control circuitry executes a modified instruction set architecture (ISA) that facilitates the broadcast distribution of data to a plurality of destination addresses in system memory circuitry. The broadcast instruction may include broadcast of a single data value to each destination address. The broadcast instruction may include broadcast of a data array to each destination address. The DMA control circuitry may also execute a reduction instruction that facilitates the retrieval of data from a plurality of source addresses in system memory and performing one or more operations using the retrieved data. Since the DMA control circuitry, rather than the processor circuitry performs the broadcast and reduction operations, system speed and efficiency is beneficially enhanced.
