12 Oct 2009 Intel's Nehalem adds the instruction POPCNT to perform the operation in hardware (or at least microcode)*. Method, Time (s), Speed up.
2 May 2017 Lists of instruction latencies, throughputs and micro-operation breakdowns for Intel, bly RAM speed. .. (POPCNT shared with Intel SSE4.2).
For example, as of this writing, the first two Google hits for popcnt benchmark (and 2 out of the top 3 bing hits) claim that Intel's hardware popcnt instruction is
23 Nov 2016 64-bit ARM architecture.1 The x64 popcnt instruction is fast: on recent Intel the speed of the an optimized popcnt-based function using AVX2:
SSE4 (Streaming SIMD Extensions 4) is a SIMD CPU instruction set used in the Intel Core Intel later introduced similar speed improvements to unaligned SSE in their Nehalem processors, but did not introduce misaligned access by . Instruction, Description. POPCNT. Population count (count number of bits set to 1).
13 Mar 2016 AVX2 faster than native popcnt instruction on Haswell/Skylake (0x80.pl) .. entire chain than its speed in terms of throughput can still be greater.
Intel introduced instruction popcnt with SSE4.2 instruction set. . is that the speed of SSSE3 code is comparable to hardware popcnt, it is just a bit slower.
28 Jun 2013 Popcount sample implementations (612 bytes, text/plain) . that a native bit count instruction (like the SSE popcnt or NEON vcnt) is not present,
4 Jun 2010 Benchmarking CRC32 and PopCnt instructions Data alignment speeds up the code by 8% and makes it more portable (thanks to Dmitry for
2 Mar 2015 There's a patent for combined popcnt, bit scan forward / reverse: the PopCount or BitScan operation, based on a microprocessor instruction.
