摘要： Embodiments of the invention are directed to a DEFLATE compression accelerator and to a method for verifying the correctness of the DEFLATE compression accelerator. The accelerator includes an input buffer and a Lempel-Ziv 77 (LZ77) compressor communicatively coupled to an output of the input buffer. A switch is communicatively coupled to the output of the input buffer and to the output of the LZ77 compressor. The switch is configured to bypass the LZ77 compressor during a compression test. The accelerator further includes a deflate Huffman encoder communicatively coupled to an output of the switch and an output buffer communicatively coupled to the deflate Huffman encoder. When the switch is not bypassed, the compressor can be modified to produce repeatable results.

摘要： A method is provided that is executable by a processor of a computer. Note that the processor is communicatively coupled to a memory of the computer, and the memory stores a response block of a call command. In implementing the method, the processor defines a sub-functions field in the response block of the call command. Further the processor indicates that a set of functions of a set of instructions are installed and available at an interface based on a corresponding sub-functions flag within the sub-functions field being set. Note that the interface is also being executed on the computer and that the set of functions being represented by the corresponding sub-functions flag. The processor further indicates that the set of functions of the set of instructions are not installed based on the corresponding sub-functions flag not being set.
