SYSTEMS AND METHODS FOR LOW LATENCY HARDWARE MEMORY MANAGEMENT

Abstract:

Presented are systems and methods that allow for efficient data processing that reduce data latency and, thus, power consumption and data management cost. In various embodiments, this is accomplished by using a sequencer that identifies an address pointer of a first data block within a memory and a length of data that comprises that data block and is related to an input of a matrix processor. The sequencer then calculates, based on the block length, the input length, and a memory map, a block count representative of a number of data blocks that are to be retrieved from the memory. Using the address pointer, the sequencer may retrieve a number of data blocks from the memory in a number of cycles that depends on whether the data blocks are contiguous. In embodiments, based on the length of data, a formatter then maps the data blocks to the input of the matrix processor.
