Subject: [dpdk-dev] [PATCH v3] Implement memcmp using SIMD intrinsics
Date: Mon, 18 May 2015 13:01:42 -0700 [thread overview]
Message-ID: <1431979303-1346-1-git-send-email-rkerur@gmail.com> (raw)
Background:
After preliminary discussion with John (Zhihong) and Tim from Intel it was
decided that it would be beneficial to use AVX/SSE intrinsics for memcmp
similar to memcpy that had been implemeneted. In addition, we decided to use
librte_hash as a test candidate to test both functionality and performance.
Further discussions lead to complete functionality implementation of memory
comparison and v3 code reflects that.
Test was conducted on Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz, Ubuntu 14.04,
x86_64, 16GB DDR3 system.
