  • Patent number: 11570489
    Abstract: An HDMI transmission device includes a packetizer circuit and a processor. A control method of controlling the HDMI transmission device includes performing a fixed rate link training, upon passing the fixed data rate link training, the processor transmitting an initial gap packet generation command to a controller of the packetizer circuit to output a selection signal to the packetizer circuit, so as to output an initial gap packet, when video data is not ready, continuously outputting the initial gap packet, when the video data is ready and a format change of the video data is detected or a signal abnormality unrelated to hot-plugging is detected, the processor transmitting a subsequent gap packet generation command to the controller to determine whether a block boundary is reached, and the controller switching the selection signal upon reaching the block boundary for the packetizer circuit to output the subsequent gap packet.

  • Patent number: 11556337
    Abstract: A matrix multiplication circuit comprises a memory storage device, processing circuitry, a parallel multiply circuit, and buffer circuits. The parallel multiply circuit simultaneously performs a count of multiplies in a parallel multiplication operation. The buffer circuits include prefetch buffer circuits each having a storage array dimension corresponding to the count of multiplies in the parallel multiplication operation. The processing circuitry loads a first prefetch buffer circuit with values from the first matrix; fetches a value of the second matrix and, in parallel with the fetch, preload the second prefetch buffer circuit with another value from the first matrix; initiates a parallel multiply of the fetched value of the second matrix and the values in the first prefetch buffer circuit; and stores partial product results of the parallel multiply, including adding a current partial product result to a previously stored partial product result.

  • Patent number: 11556344
    Abstract: Embodiments herein describe transferring ownership of data (e.g., cachelines or blocks of data comprising multiple cachelines) from a host to hardware in an I/O device. In one embodiment, the host and I/O device (e.g., an accelerator) are part of a cache-coherent system where ownership of data can be transferred from a home agent (HA) in the host to a local HA in the I/O deviceā€”e.g., a computational slave agent (CSA). That way, a function on the I/O device (e.g., an accelerator function) can request data from the local HA without these requests having to be sent to the host HA. Further, the accelerator function can indicate whether the local HA tracks the data on a cacheline-basis or by a data block (e.g., multiple cachelines). This provides flexibility that can reduce overhead from tracking the data, depending on the function's desired use of the data.

  • Patent number: 11436040
    Abstract: A new approach of systems and methods to support a hierarchical interrupt propagation scheme for efficient interrupt propagation and handling is proposed. The hierarchical interrupt propagation scheme organizes a plurality of slave interrupt handlers associated functional blocks in a chip in a hierarchy. When an exception or error condition occurs in a functional block, a slave interrupt handler associated with the functional block creates an interrupt packet as an interrupt notification and utilizes pre-existing input and output interfaces that have already been utilized for accessing registers of the functional block to transmit the created interrupt packet to a central interrupt handler through the hierarchy without running dedicated interconnect wires out of the functional block.
