  • Patent number: 11615050
    Abstract: A system timer bus used by the processor elements in an ARM-based system on a chip (SoC) is driven using a Precision Time Measurement (PTM) value. This allows the processor elements to be synchronized to the PCIe ports that use PTM. When two SoCs are connected using PCIe links, this example allows the processor elements in both SoCs to be synchronized. As the processor elements are synchronized, associated tasks on the two SoCs are synchronized, so that overall operations are synchronized.

  • Patent number: 11611745
    Abstract: According to an aspect, a video encoder selects a block of intermediate size from a set of block sizes for intra-prediction estimation for encoding a video signal. A set of neighbouring blocks with the intermediate size are tested for combining. If the set of neighbouring blocks are determined to be combinable, the video encoder selects a larger block size formed by the tested neighbouring blocks for encoding. On the other hand, if the set of neighbouring blocks are determined to be not combinable, the video encoder selects a smaller block size from the set of tested neighbouring blocks for prediction. According to another aspect, the best mode for intra-prediction is determined by first intra-predicting a block with intermediate modes in a set of modes. Then the intra-predictions are performed for the neighbouring modes of at least one intermediate mode.

  • Patent number: 11552382
    Abstract: A radio frequency (RF) loopback substrate or printed circuit board (PCB) which contains receive and transmit antennas located on the bottom of the loopback substrate which are aligned with the complementary transmit and receive antennas on an antenna on package (AOP) device under test. The loopback substrate receive and transmit antennas are coupled to each other. The device under test contacts are driven by a conventional tester, which causes RF circuitry in the integrated circuit to drive an AOP transmit antenna. The corresponding loopback substrate receive antenna receives the RF signal from the AOP transmit antenna and provides it to the loopback substrate transmit antennas. The integrated circuit package AOP receive antennas then receive the RF signals from the loopback substrate transmit antennas. The signals at the integrated circuit package AOP receive antennas are monitored through the integrated circuit contacts to monitor the received RF signals.

  • Patent number: 11537532
    Abstract: A queuing requester for access to a memory system is provided. Transaction requests are received from two or more requestors for access to the memory system. Each transaction request includes an associated priority value. A request queue of the received transaction requests is formed in the queuing requester. Each transaction request includes an associated priority value. A highest priority value of all pending transaction requests within the request queue is determined. An elevated priority value is selected when the highest priority value is higher than the priority value of an oldest transaction request in the request queue; otherwise the priority value of the oldest transaction request is selected. The oldest transaction request in the request queue with the selected priority value is then provided to the memory system. An arbitration contest with other requesters for access to the memory system is performed using the selected priority value.

  • Patent number: 11537309
    Abstract: In described examples, circuitry for saving and restoring a design block state includes first memories configured to receive, and store in different first memories in a first order, different portions of first data; and a second memory coupled to first memories. First memories with the most memory cells have N memory cells. First memories with fewer memory cells have M memory cells. When saving state, first data from different first memories is written in a second order to different corresponding regions of the second memory as second data. The second order repeats portions of the first data stored in sequentially first N mod M cells, determined using the first order, of corresponding first memories with fewer cells. When restoring state, second data is read from the second memory and stored, in the first order, in corresponding first memories; repeated portions are repeatedly stored in corresponding first memories with fewer cells.
