Parallel filtering method and corresponding device

The invention discloses a parallel filtering method and a corresponding device. The device comprises a multi-granularity storer, a data caching device, a coefficient buffering and broadcasting device, a vector operation device and a command queuing device, wherein the multi-granularity storer is used for storing to-be-filtered data, a filtering coefficient and filtering result data; the data caching device is used for caching, reading and updating the to-be-filtered data taken out; the coefficient buffering and broadcasting device is used for caching and broadcasting the filtering coefficient taken out; the command queuing device is used for storing and outputting a parallel filtering operation command; and the vector operation device is used for conducting vector operation based on the to-be-filtered data and output coefficient data, and for writing an operation result in the multi-granularity storer. The invention further discloses the parallel filtering method. According to the parallel filtering method and the corresponding device, the filtering speed is high; the access storage time is reduced; the service efficiency of the data is improved; the power consumption is reduced; and an application scope is wide.
