Abstract: An execution circuit inputs a plurality of data units, performs unit operations on the data units, and registers results of the unit operations in response to oscillations of a clock signal. A control circuit controls activation of the unit operations, and outputs a start signal to the execution circuit to activate each unit operation and/or a completion signal to indicate completion of each unit operation. A debug circuit stores breakpoint flags associated with the unit operations. Each breakpoint flag has a state that specifies whether to stop oscillations of the clock signal. The debug circuit further receives the start and/or completion signal and evaluates, while the clock signal oscillates to the execution circuit, a state of the start and/or completion signal and a state of the breakpoint flag associated with the unit operation. Oscillations of the clock signal are stopped in response to the evaluation of the signals.

Abstract: An execution circuit is configured to input data units, perform unit operations on the data units, and register results of the unit operations in response to oscillations of a clock signal. A control circuit controls activation and deactivation of the unit operations. A debug circuit inputs, in parallel with input of the data units to the execution circuit, at least one of the data unit or one or more attributes associated with the data unit. The debug circuit evaluates, upon each input of the at least one of the data unit or the one or more attributes, a breakpoint condition based on the at least one of the data unit or the one or more attributes while the clock signal oscillates. In response to evaluation of the breakpoint condition indicating a break, the debug circuit stops oscillations of the clock signal to the execution circuit.
