WebP lossy compression method and apparatus

The invention discloses a WebP lossy compression method and apparatus. The method comprises the following steps: storing original image data in a buffer node of an FPGA terminal based on multi-thread parallel execution; reading the buffer node in a first queue, sending a compression instruction to the FPGA terminal, so that the FPGA terminal executes FPGA algorithm logic, compressing the original image data to obtain compressed image data, and storing the compressed image data in a second buffer; reading the buffer node in a second queue, storing the compressed image data in the second buffer in a third buffer; and reading the third buffer in a third queue, and performing encoding to obtain lossy compression data. According to the WebP lossy compression method and apparatus disclosed by the invention, the serial processing flow of WebP lossy compression is optimized into pipelined execution on the basis of the multi-thread parallel execution, and the synchronization of the steps is realized by using the queue
