2results about How to "Reduce Design Risk" patented technology

The invention discloses a compression and decompression test platform and method based on special hardware, virtual electronic equipment and a storage medium, the platform is deployed in a computing system comprising a special compression and decompression hardware unit, and a kernel mode driving module is in communication connection with the special compression and decompression hardware unit. The user mode test program module is connected with the kernel mode drive module through a character device interface; registering a character device to create an interface with the dedicated compression / decompression hardware unit; in response to a user mode instruction received through character equipment, distributing a source data buffer area and a target data buffer area through a DMA-BUF HEAP mechanism; establishing a zero-copy shared memory channel of a user mode and a kernel mode; writing the to-be-tested data into a source data buffer area; allocating a shared memory buffer area and managing for compression and decompression operations by utilizing a DMA memory management mechanism of the kernel; and determining a test mode, processing the target and outputting a test result. Repeated development of test tools is avoided, and cost is saved.
