摘要： An integrated circuit includes a compression accelerator to process a request from software to compress source data into an output file. The compression accelerator includes early-abort circuitry to provide for early abort of compression operations. In particular, the compression accelerator uses a predetermined sample size to compute an estimated size for a portion of the output file. The sample size specifies how much of the source data is to be analyzed before computing the estimated size. The compression accelerator also determines whether the estimated size reflects an acceptable amount of compression, based on a predetermined early-abort threshold. The compression accelerator aborts the request if the estimated size does not reflect the acceptable amount of compression. The compression accelerator may complete the request if the estimated size reflects the acceptable amount of compression. Other embodiments are described and claimed.

摘要： Apparatus and method for detecting a constant data block are described herein. An apparatus embodiment includes compression circuitry to perform compression operations on a memory block; constant detection circuitry to, concurrently with performance of the compression operations on the memory block, determine that the memory block is a constant data block comprised of only repeat instances of a constant value; and controller circuitry to associate a first indication with the memory block based on the determination, the first indication usable for controlling whether to abort the compression operations or whether to discard a compressed memory block generated from the compression operations.
