Verifying compressed stream fused with copy or transform operations

An apparatus comprising:

• decoder circuitry to decode an instruction, the instruction to include a field corresponding to a fused copy/transform operation enablement;
• and
• execution circuitry to execute the decoded instruction in accordance with the field to cause:
• compression logic circuitry to compress input data and to store the compressed data in a temporary buffer, wherein the compression logic circuitry is to determine a first checksum value corresponding to the compressed data stored in the temporary buffer;
• and
• decompression logic circuitry to perform a decompress-verify operation and a copy operation,
• wherein the decompress-verify operation is to decompress the compressed data stored in the temporary buffer to determine a second checksum value corresponding to the decompressed data from the temporary buffer, wherein the copy operation is to transfer the compressed data from the temporary buffer to a destination buffer in response to a match between the first checksum value and the second checksum value, wherein a page fault is to be triggered in response to an access to the compressed data stored in the destination buffer, wherein the page fault is to cause the decompression logic circuitry to decompress the compressed data stored in the destination buffer.

One or more non-transitory computer-readable media comprising one or more instructions that when executed on a processor configure the processor to perform one or more operations to cause:

• compression logic circuitry to compress input data and to store the compressed data in a temporary buffer, wherein the compression logic circuitry is to determine a first checksum value corresponding to the compressed data stored in the temporary buffer;
• and
• decompression logic circuitry to perform a decompress-verify operation and a copy operation,
• wherein the decompress-verify operation is to decompress the compressed data stored in the temporary buffer to determine a second checksum value corresponding to the decompressed data from the temporary buffer, wherein the copy operation is to transfer the compressed data from the temporary buffer to a destination buffer in response to a match between the first checksum value and the second checksum value, wherein a page fault is to be triggered in response to an access to the compressed data stored in the destination buffer, wherein the page fault is to cause the decompression logic circuitry to decompress the compressed data stored in the destination buffer.
