Event-based debug, trace, and profile in device with data processing engine array

A method for operating a die, the method comprising:

• operating a plurality of data processing engines (DPEs) of an array of DPEs on the die, each of the plurality of DPEs comprising a core and a memory module;
• during operation of a first DPE of the plurality of DPEs, detecting an event in the core or the memory module of the first DPE by event logic in the first DPE, wherein the event logic comprises stall logic configured for operations selected from the group comprising:
• halting execution of the core, resuming execution of the core, setting breakpoints, and synchronizing a timer based on writable configuration registers and the event detected by the event logic;
• and
• in response to detecting the event, broadcasting an indication of the detected event from the first DPE to at least two of the plurality of DPEs via an event broadcast network, the event broadcast network comprising interconnected event broadcast circuitry of the plurality of DPEs.

A device comprising:

• an array of data processing engines (DPEs) on a die, each of the DPEs comprising:
• a core;
• a memory module;
• core event logic in the core, the core event logic being configured to detect an occurrence of a first one or more events in the core, wherein the core event logic comprises stall logic configured for operations selected from the group comprising:
• halting execution of the core, resuming execution of the core, setting breakpoints, and synchronizing a timer based on writable core configuration registers and the first one or more events detected by the core event logic;
• memory event logic in the memory module, the memory event logic being configured to detect an occurrence of a second one or more events in the memory module;
• a first event broadcast circuitry connected to the core event logic, the first event broadcast circuitry being configurable to propagate a first received signal selectively in a first one or more predefined directions, wherein the first received signal is a respective indication for each of the first one or more events after the first one or more events occurred;
• and
• a second event broadcast circuitry connected to the memory event logic, the first event broadcast circuitry being connected to the second event broadcast circuitry, the second event broadcast circuitry being configurable to propagate a second received signal selectively in a second one or more predefined directions, wherein the second received signal is a respective indication for each of the second one or more events after the second one or more events occurred, and
• wherein the first event broadcast circuitry and the second event broadcast circuitry of the DPEs are interconnected to form an event broadcast network, and wherein the first event broadcast circuitry and the second event broadcast circuitry uses the event broadcast network to propagate the first received signal and the second received signal.
