    35In this section, we discuss the scalability and performance advantages
     
    3133SIMD instruction count of Parabix on AVX.  However, in the \SB\ AVX
    3234implementation, Intel has focused primarily on floating point
    33 operations as opposed to the integer based operations.  256-bit SIMD
    34 is available for loads, stores, bitwise logic and floating operations,
    35 whereas SIMD integer operations and shifts are only available in the
    36 128-bit form.

     36logic and floating operations, whereas SIMD integer operations and
     37shifts are only available in the 128-bit form.
