A method and apparatus are provided for dynamically determining when an operation, specified by one or more instructions in a data processing system, is suitable for accelerated execution. Data indicators are maintained, for data registers of the system, that indicate when data-flow from a register derives from a restricted source. In addition, instruction predicates are provided for instructions to indicate which instructions are capable of accelerated execution. From the data indicators and the instruction predicates, the microarchitecture of the data processing system determines, dynamically, when the operation is a thread-restricted function and suitable for accelerated execution in a hardware accelerator. The thread-restricted function may be executed on a hardware processor, such as a vector, neuromorphic or other processor.

A method and apparatus of performing a data transmission from an electronic device or a peripheral device of an electronic device to a peripheral device of a remote electronic device is disclosed. One example method of performing the data transmission may include transmitting data designated for the remote peripheral device to a local virtual device object. The data that is received by the local virtual device object is transmitted via at least one communication interface or peripheral device of the electronic device to at least one remote communication interface or peripheral device of the remote electronic device. The data arriving at the least one remote communication interface or peripheral device of the remote electronic device is received by a remote virtual device object and transmitted to the designated remote peripheral device.

An apparatus for managing input/output (I/O) data may include a streaming I/O controller to receive data from a load/store domain component and output the data as first streaming data of a first data type comprising a first data movement type and first data format type. The apparatus may also include at least one accelerator coupled to the streaming I/O controller to receive the first streaming data, transform the first streaming data to second streaming data having a second data type different than the first data type, and output the second streaming data. In addition, the apparatus may include a streaming interconnect to conduct the second data to a peer device configured to receive data of the second data type.

A system and method for managing data in a ring buffer is disclosed. The system includes a legacy ring buffer functioning as an on-chip ring buffer, a supplemental buffer for storing data in the ring buffer, a preload ring buffer that is on-chip and capable of receiving preload data from the supplemental buffer, a write controller that determines where to write data that is write requested by a write client of the ring buffer, and a read controller that controls a return of data to a read client pursuant to a read request to the ring buffer.

A systolic array implemented in circuitry of an integrated circuit includes a processing element array including processing elements. The systolic array includes one or more feeder circuits communicatively coupled to the processing element array. Each of the one or more feeder circuits includes a first section configured to receive data stored in memory external to the integrated circuit, and a second section configured to send the received data to the processing element array, wherein data transferring from the memory to the processing element array is double buffered by the first section and the second section. The systolic array also includes one or more drain circuits communicatively coupled to the processing element array, including one or more memory buffers configured to store data output by the processing element array.

A communication interface includes one or more input/output circuitries, each input/output circuitry including a pointer generation block that controls write pointers of a respective input/output circuitry and read pointers of the respective input/output circuitry. Each input/output circuitry also includes input/output buffers communicatively coupled to the pointer generation block. Each input/output circuitry further includes a receive delay-locked loop that provides a clock signal to the plurality of input/output buffers. Each input/output circuitry also includes one or more transmit delay-locked loops that delay the clock signal.

Integrated circuit packages with multiple integrated circuit dies are provided. A multichip package may include a substrate, a main die that is mounted on the substrate, and multiple transceiver daughter dies that are mounted on the substrate and that are coupled to the main die via corresponding Embedded Multi-die Interconnect Bridge (EMIB) interconnects formed in the substrate. Each of the main die and the daughter dies may include configurable adapter circuitry for interfacing with the EMIB interconnects. The adapter circuitry may include FIFO buffer circuits operable in a 1 mode or 2 mode and configurable in a phase-compensation mode, a clock-compensation mode, an elastic mode, and a register bypass mode to help support a variety of communications protocols with different data width and clocking requirements. The adapter circuitry may also include boundary alignment circuitry for reconstructing (de)compressed data streams.

Provided is a device configured to perform a convolution operation. The device includes bi-directional First In First Out memory including bi-directional latches configured to transfer data in a first direction or a second direction depending on a clock signal and connected to each other and performs a convolution operation of an input value and a filter. The device stores first input values corresponding to a window equivalent to a size of the filter from a input value matrix in the bi-directional First In First Out memory in response to a first convolution operation and stores second input values corresponding to a location of the window which is moved in the first direction or the second direction by a predetermined amount from locations of the first input values in the bi-directional First In First Out memory in response to a second convolution operation subsequent to the first convolution operation.

A sorter receives a list of elements to be sorted. The elements are supplied to a communication bus. A plurality of processing modules are coupled to the communication bus and examine each list element supplied on the bus to see if the list element has a value that is within a range of values processed by the list element. The range of values of the list are subdivided to ranges allocated to the processing modules. When a processing modules determines an element in the bus is within its range, it stores the value and sorts the value in storage dedicated to storing a sorted list of values with the allocated range.

A system, method and computer readable medium for operating a First In, First Out (FIFO) buffer that transfers data between a host and a plurality of endpoints using chip select is disclosed. The method includes receiving a current value of a read pointer and a status for an active endpoint and reading data at a location to which the read pointer points and setting a tag associated with the location to which the read pointer points to indicate availability.
