Abstract: Systems, apparatuses, and methods for implementing a low power filter. A low power filter may generate a reference sum from a reference vector in order to reduce the number of additions which are needed to filter an input sample vector. The reference sum may be used as the starting point for filtering the input sample vector. Then, each input sample of the input sample vector may be compared to a corresponding reference vector sample. If an input sample is different from the corresponding reference vector sample, a correction value based on the corresponding filter coefficient value may be added or subtracted from the reference sum. After all input samples have been compared to corresponding reference vector values and all correction values applied to the reference sum, the modified reference sum may be the output of the filter.

Abstract: A method, including receiving, by an extended virtual function shell positioned on a Peripheral Component Interconnect Express (PCIe) configuration space, a virtual function call comprising a request to perform a specific computation, and identifying a physical function associated with the called virtual function, the physical function one of multiple physical functions positioned on the PCIe configuration space. One or more first data values are then retrieved from a virtual function instance stored in the memory, one or more first data values, the virtual function instance associated with the called virtual function, and one or more second data values are retrieved from the identified physical function. The specific computation is then performed using the first data values and the second data values, thereby calculating a result.

Abstract: An apparatus, including a first multiple of virtual function clusters positioned on a Peripheral Component Interconnect Express (PCIe) configuration space, each of the clusters comprising at least one virtual function, and a second multiple of physical functions positioned on the PCIe configuration space. The apparatus also includes an extended virtual function shell positioned on the PCIe configuration space and configured to select one of the physical functions, to select one of the available virtual function clusters and to associate the selected virtual function cluster with the selected the physical function.
