  • Publication number: 20220229796
    Abstract: A register bank of a channel of a direct memory access circuit is initialized. Transfer cycles are executed as configured by the register bank, and updates are made to the registers from a memory. At each transfer cycle, an operation is performed in accordance with a first field of the register bank to either: carry on the execution or generate a first signal and suspend the execution. In response to each reception of the first signal by a central processing unit, an operation is performed to either: generate a second signal or modify the content of the register band and/or record into the memory a first item representative of a next update of the register bank. A second signal is then generated.

  • Patent number: 11354251
    Abstract: A method of offloading a computing kernel from a host central processing unit (CPU) to a co-processor includes obtaining, by an application running on the host CPU, a virtual address of a packet in a user level queue of a general packet processing unit (GPPU) and initializing, by the application, the packet referenced by the virtual address using an application programming interface of a user level device driver (ULDD). The packet includes a plurality of handles corresponding to the computing kernel. The method further includes finalizing, by the ULDD, the packet by including a list of bootstrap translation addresses comprising a physical address and a virtual address for each of the plurality of handles and output by a kernel level device driver (KLDD) of an operating system running on the host CPU, and accessing, by the application using the virtual address, results obtained from the co-processor processing the computing kernel.
