Abstract: Provided is a method for the collection and storage of information related to the operation of a chip module. The disclosed technology provides a chip data collection and storage controller. In one embodiment, a chip module is provided with a stand-alone memory that records information relevant to potential debugging operations. The stand-alone memory is on the same chip module as the chip die but is not part of the chip die. A data bus is provided between the chip module and the memory. In addition, the memory has I/O access so that information can be accessed in the event that the chip module cannot be accessed. Stored information includes, but is not limited to, environmental conditions, performance information, errors, time usage, run time, number of power on cycles, the highest temperature experience by the chip, wafer and x, y data, manufacturing info, FIR errors, and PRSO, SRAM PSRO values.

Abstract: Exemplary embodiments provide a computer-implemented method and a system for a startup cycle for a cycle deterministic start. An initializing mechanism applies power to a microprocessor. The initializing mechanism initializes the configuration of the microprocessor. The initializing mechanism initializes a timer. The initializing mechanism then sends a clock start command to the microprocessor. The clocks on the microprocessor are started. Upon the clocks starting, the timer begins and allows temporary transients, such as voltage droop due to a large instantaneous change in demand for current due to the commencement of clock switching. Responsive to the timer reaching a target value, an interrupt unit sends a system reset interrupt. Responsive to the interrupt unit sending the system reset interrupt, an instruction fetch unit fetches a first instruction. This operation will be deterministic to the state of the rest of the microprocessor memory elements (latches, arrays, et al.).

Abstract: A processor core for transitioning a debugging unit between a plurality of operating states generates trace data as it processes operating signals of an instruction stream. The processor core provides a trigger event signal to the debugging unit in response to a trigger instruction signal within the instruction stream that is representative of triggering instruction for transitions debugging unit to one of (1) a base operating state, (2) a dynamic storage operating state or (3) a static storage operating state. Concurrently or alternatively, the processor core can provide the trigger event signal to the debugging unit as a function of generated trigger data in response to additional operational instructions within the instruction stream.

Abstract: A processor core for transitioning a debugging unit between a plurality of operating states in response to an instruction stream is disclosed. The processor core generates trace data as it processes operating signals of the instruction stream. The processor core provides a first trigger event signal to the debugging unit in response to a first trigger instruction signal within the instruction stream that is representative of a triggering instruction to transitions the debugging unit to a base operating state. The processor core provides a second trigger event signal to the debugging unit in response to a second trigger instruction signal within the instruction stream that is representative of a triggering instruction to dynamically store trace data within the memory component of the debugging unit.
