Abstract: Data routing for efficient decompressor use is described. In accordance with the described techniques, a cache controller receives requests from multiple requestors for elements of data stored in a compressed format in a cache. The requests include at least a first request from a first requestor and a second request from a second requestor. A decompression routing system identifies a redundant element of data requested by both the first requestor and the second requestor and causes decompressors to decompress the requested elements of data. The decompression includes performing a single decompression of the redundant element. After the decompression, the decompression routing system routes the decompressed elements to the plurality of requestors, which includes routing the decompressed redundant element to both the first requestor and the second requestor.

Abstract: An integrated circuit (IC) device includes a ring transport having a plurality of nodes and a wire interconnect coupling the plurality of nodes in a ring. The wire interconnect including a wire to transmit clock wake signals around the ring transport in advance of data signaling representing a data packet. Each node is to switch from a clock gated state to a clocked state responsive to receiving a clock wake signal. The ring transport further includes a sleep controller coupled to a select node of the plurality of nodes. The sleep controller is to configure the select node into a clock suppression state for a specified duration responsive to identifying an idle condition on the ring transport via monitoring of the wire. While in the clock suppression state the node suppresses further transmission of any clock wake signals received at the select node.

Abstract: Systems, apparatuses, and methods for performing efficient data transfer in a computing system are disclosed. A computing system includes multiple fabric interfaces in clients and a fabric. A packet transmitter in the fabric interface includes multiple queues, each for storing packets of a respective type, and a corresponding address history cache for each queue. Queue arbiters in the packet transmitter select candidate packets for issue and determine when address history caches on both sides of the link store the upper portion of the address. The packet transmitter sends a source identifier and a pointer for the request in the packet on the link, rather than the entire request address, which reduces the size of the packet. The queue arbiters support out-of-order issue from the queues. The queue arbiters detect conflicts with out-of-order issue and adjust the outbound packets and fields stored in the queue entries to avoid data corruption.

Abstract: A system and method for updating power supply voltages due to variations from aging are described. A functional unit includes a power supply monitor capable of measuring power supply variations in a region of the functional unit. An age counter measures an age of the functional unit. A control unit notifies the power supply monitor to measure an operating voltage reference. When the control unit receives a measured operating voltage reference, the control unit determines an updated age of the region different from the current age based on the measured operating voltage reference. The control unit updates the age counter with the corresponding age, which is younger than the previous age in some cases due to the region not experiencing predicted stress and aging. The control unit is capable of determining a voltage adjustment for the operating voltage reference based on an age indicated by the age counter.

Abstract: A cache includes an upstream port, a cache memory for storing cache lines each having a line width, and a cache controller. The cache controller is coupled to the upstream port and the cache memory. The upstream port transfers data words having a transfer width less than the line width. In response to a cache line fill, the cache controller selectively determines data bus inversion information for a sequence of data words having the transfer width, and stores the data bus inversion information along with selected inverted data words for the cache line fill in the cache memory.

Abstract: Techniques for performing cache operations are provided. The techniques include recording an indication that providing exclusive access of a first cache line to a first processor is deemed problematic; detecting speculative execution of a store instruction by the first processor to the first cache line; and in response to the detecting, refusing to provide exclusive access of the first cache line to the first processor, based on the indication.

Abstract: A load/store unit includes a first queue including a first entry for a store operation and a second queue including a second entry for a load operation that includes a return instruction that redirects a program flow to a location indicated by the return instruction. The load/store unit also includes a processor to determine that the store operation matches the load operation and selectively perform store-to-load forwarding (STLF) of a return address for the return instruction from the first entry to the second entry based on whether the store operation is associated with a call instruction. The load/store unit forwards the return address to the second entry in response to the store operation being associated with the call instruction. The load/store unit blocks forwarding until the store operation retires in response to the store operation not being associated with the call instruction.

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: Methods and devices are provided for processing image data on a sub-frame portion basis using layers of a convolutional neural network. The processing device comprises memory and a processor. The processor is configured to receive frames of image data comprising sub-frame portions, schedule a first sub-frame portion of a first frame to be processed by a first layer of the convolutional neural network when the first sub-frame portion is available for processing, process the first sub-frame portion by the first layer and continue the processing of the first sub-frame portion by the first layer when it is determined that there is sufficient image data available for the first layer to continue processing of the first sub-frame portion. Processing on a sub-frame portion basis continues for subsequent layers such that processing by a layer can begin as soon as sufficient data is available for the layer.

Abstract: A processing system includes a controller of a transmitting module for transmitting data to a receiving module across an interconnect compliant with a processor interconnect protocol. The controller indicates the beginning and end of a variable-length data burst using data primitives that are N symbols (bytes) in length, rather than using data primitives that are M symbols in length, as specified by the processor interconnect protocol, where N<M. The controller of the transmitting module signals the beginning of a data burst by sending a short primitive indicating either the beginning of a data burst or signaling the receiving module to reset error detection logic so that error detection information based on the data burst can be calculated. The controller automatically inserts another short primitive indicating the end of a data burst when there is no data to transmit, thus accommodating data bursts of variable lengths.
