Abstract: A streaming engine in a system receives a first set of stream parameters into a queue to define a first stream along with an indication of either a queue mode of operation or a speculative mode of operation for the first stream. Acquisition of the first stream then begins. At some point, a second set of stream parameters is received into the queue to define a second stream. When the queue mode of operation was specified for the first stream, the second set of parameters is queued and acquisition of the second stream is delayed until completion of acquisition of the first stream. When the speculative mode of operation was specified for the first stream, acquisition of the first stream is canceled upon receipt of the second set of stream parameters and acquisition of the second stream begins immediately.

Abstract: In described examples, an integrated circuit (IC) includes a matrix multiplication accelerator including a first memory, a second memory, and a memory controller. The second memory is configured to store multiple rows of an input feature map on a single line of cells of the memory, and to store a filter kernel. The memory controller reads multiple contiguous memory vectors of the second memory, different ones of the contiguous memory vectors corresponding to different portions of the input feature map. The memory controller also replaces (with padding zeroes) values of respective ones of the contiguous memory vectors. The number and location of replaced values are selected in response to a column index of an element of the filter kernel in response to which the respective contiguous memory vector is read. Zero padded contiguous memory vectors are written to the first memory.
