Tensor processor visualization and analysis tool

A method comprising:

• receiving a compiled program specifying instructions to be run on a processor;
• the processor comprising one or more data paths, each comprising a plurality of data lanes connecting a row of functional units, each functional unit configured to process data received from the data path or output processed data onto the data path to be received by at least one other functional unit of the row, in accordance with the plurality of instructions;
• and
• wherein the compiled program comprises data indicating a predetermined timing at which each functional unit of the row receives instructions of the plurality of instructions for processing data;
• providing user interface data for displaying an interactive user interface comprising:
• an interactive interface objects configured to receive a user selection indicating a time cycle of the compiled program, and displayed intersections between functional units of a data path of the one or more data paths and the plurality of data lanes of the data path in either direction;
• and
• providing, in response to receiving the user selection indicating the time cycle, user interface data to update the user interface to display, indications at each of one or more intersections, each indicating that a functional unit associated with a respective intersection is outputting data onto a data lane associated with the intersection or consuming data from the data lane during the selected time cycle.

A system comprising:

• a compiler configured to:
• receive program code to be run on a processor;
• generate a compiled program from the received program code, the compiled program specifying instructions to be run on the processor;
• wherein the processor comprises one or more data paths, each comprising a plurality of data lanes connecting a row of functional units, each functional unit configured to process data received from the data path or output processed data onto the data path to be received by at least one other functional unit of the row, in accordance with the instructions;
• and
• wherein the compiled program includes information for a visualization model for a visualizer indicating a predetermined timing at which each functional unit of the row receives data along a first data path and instructions of the plurality of instructions along a second data path for processing data.
