Abstract: The disclosure provides a sample adaptive offset (SAO) encoder. The SAO encoder includes a statistics collection (SC) block and a rate distortion optimization (RDO) block coupled to the SC block. The SC block receives a set of deblocked pixels and a set of original pixels. The SC block categorizes each deblocked pixel of the set of deblocked pixels in at least one of a plurality of band and edge categories. The SC block estimates an error in each category as difference between a deblocked pixel of the set of deblocked pixels and corresponding original pixel of the set of original pixels. The RDO block determines a set of candidate offsets associated with each category and selects a candidate offset with a minimum RD cost. The minimum RD cost is used by a SAO type block and a decision block to generate final offsets for the SAO encoder.

Abstract: An Ethernet switch and a switch microcontroller or CPU are integrated onto a system-on-a-chip (SoC). The Ethernet switch remains independently operating at full speed even though the remainder of the SoC is being reset or is otherwise nonoperational. The Ethernet switch is on a separated power and clock domain from the remainder of the integrated SoC. A warm reset signal is trapped by control microcontroller (MCU) to allow the switch CPU to isolate the Ethernet switch and save state. When the Ethernet switch is isolated and operating independently, the warm reset request is provided to the other entities on the integrated SoC. When warm reset is completed, the state is restored and the various DMA and flow settings redeveloped in the integrated SoC to allow return to normal operating condition.

Abstract: In some examples, a system on chip (SOC) comprises a network switch configured to receive a packet and to identify a flow identifier (ID) corresponding to a header of the packet. The SOC comprises a direct memory access (DMA) controller coupled to the network switch, where the DMA controller is configured to divide the packet into first and second fragments based on the flow ID and to assign a first hardware queue to the first fragment and a second hardware queue to the second fragment, and wherein the DMA controller is further configured to assign memory regions to the first and second fragments based on the first and second hardware queues. The SOC comprises a snoopy cache configured to store the first fragment to the snoopy cache or to memory based on a first cache allocation command, where the first cache allocation command is based on the memory region assigned to the first fragment, where the snoopy cache is further configured to store the second fragment to the snoopy cache or to memory based on a second cache allocation command, and where the second cache allocation command is based on the memory region assigned to the second fragment.

Abstract: An electronic device may be configured to detect a fault in imaging and vision hardware accelerators. The electronic device may include a controller configured to select a first golden input frame of multiple golden input frames to perform a first self-test, and retrieve a first reference image signature corresponding to the first golden input frame. The electronic device may include a hardware accelerator module configured to obtain the first golden input frame, and generate a first output frame based on the first golden input frame. The electronic device may include a signature generator configured to generate a first generated image signature based on the first output frame. The electronic device may include a signature comparison module configured to compare the first generated image signature to the first reference image signature in order to determine whether the hardware accelerator module includes a fault at a first time.

Abstract: A peripheral proxy subsystem is placed between multiple hosts, each having a root controller, and single root I/O virtualization (SR-IOV) peripheral devices that are to be shared. The peripheral proxy subsystem provides a root controller for coupling to the endpoint of the SR-IOV peripheral device or devices and multiple endpoints for coupling to the root controllers of the hosts. The peripheral proxy subsystem maps the virtual functions of an SR-IOV peripheral device to the multiple endpoints as desired to allow the virtual functions to be allocated to the hosts. The physical function of the SR-IOV peripheral device is managed by the peripheral proxy device to provide the desired number of virtual functions. The virtual functions of the SR-IOV peripheral device are then presented to the appropriate host as a physical function or a virtual function.
