A download dispatch circuit initiates download of an input tile of an input feature map in response to a source buffer of two or more source buffers being available for the input tile, and indicates that the input tile is available in response to completion of the download. An operation dispatch circuit initiates a neural network operation on the input tile in response to the input tile being available and a first destination buffer of two or more destination buffers being available for an output tile of an output feature map, and indicates that the output tile is available in response to completion of the neural network operation. An upload dispatch circuit initiates upload of the output tile to the output feature map in response to the output tile being available, and indicates that the first destination buffer is available in response to completion of the upload.

Tiling control circuit for downloading and processing an input tile based on source and destination buffer availability

A circuit arrangement includes a memory circuit, data upload circuitry, data formatting circuitry, and a systolic array (SA). The data upload circuitry inputs a multi-dimensional data set and stores the multi-dimensional data set in the memory circuit. The data formatting circuitry reads subsets of the multi-dimensional data set from the memory circuit. The data formatting circuitry arranges data elements of the subsets into data streams, and outputs data elements in the data streams in parallel. The SA includes rows and columns of multiply-and-accumulate (MAC) circuits. The SA inputs data elements of the data streams to columns of MAC circuits in parallel, inputs filter values to rows of MAC circuits in parallel, and computes an output feature map from the data streams and the filter values.

Systems and methods may provide for determining, in a first domain that manages a state of a second domain, that the second domain is in the state and determining, in the first domain, that a periodic action has been scheduled to occur in the second domain while the second domain is in the state. Additionally, the periodic action may be documented as a missed event with respect to the second domain. In one example, documenting the periodic action as a missed event includes incrementing a missed event counter.
