Abstract: An apparatus includes logic circuitry that selects a retag transaction identifier for an original transaction identifier of an incoming transaction request, based on a plurality of sub-groups of retag tracking data. Each sub-group of retag tracking data is associated with a corresponding sub-group of retag transaction identifiers in a group of retag transaction identifiers. The logic circuitry retags the incoming transaction request with the selected retag transaction identifier (ID) by replacing the original transaction identifier associated with the incoming transaction request and sends the retagged incoming transaction request to a target. A returned response is received from the target. The retag transaction ID in the returned response is removed and replaced with the original transaction ID before being sent as a reply to the requesting unit. Associated methods are also presented.

Abstract: A method for performing stutter of dynamic random access memory (DRAM) where a system on a chip (SOC) initiates bursts of requests to the DRAM to fill buffers to allow the DRAM to self-refresh is disclosed. The method includes issuing, by a system management unit (SMU), a ForceZQCal command to the memory controller to initiate the stutter procedure in response to receiving a timeout request, such as an SMU ZQCal timeout request, periodically issuing a power platform threshold (PPT) request, by the SMU, to the memory controller, and sending a ForceZQCal command prior to a PPT request to ensure re-training occurs after ZQ Calibration. The ForceZQCal command issued prior to PPT request may reduce the latency of the stutter. The method may further include issuing a ForceZQCal command prior to each periodic re-training.

Abstract: A system for performing a scan test of a processor core includes a scan test module and a processor including a processor core and an input/output die, where the input/output die is coupled to the processor core. The scan test module transmits, in parallel to the input/output die, scan test input data. A serializer/deserializer module of the input/output die receives the input data, serializes the input data, and transmits the serialized input data to the processor core. A serializer/deserializer module of the processor core receives the serialized scan test input data, deserializes the input data, receives result data generated in dependence upon the input data, serializes the result data, and transmits the serialized result data to the input/output die. The input/output die serializer/deserializer module receives the result data, deserializes the result data, and provides the result data to the scan test module. Error detection can be carried out through redundancy.

Abstract: A processing system includes physical function circuitry to execute virtual functions and a processing unit configured to operate in a first mode that allows more than one virtual function to execute on the physical function circuitry and a second mode that constrains the physical function circuitry to executing a single virtual function. A first virtual function modifies a state of the processing unit in response to the processing unit being in the second mode. A host driver executing on the processing unit modifies an operating mode indicator to indicate that the processing unit is operating in the first mode or to indicate that the processing unit is operating in the second mode. Microcode executing on the processing unit accesses the operating mode indicator to determine whether the processing unit is operating in the first mode or the second mode.
