WebIntel's math library (distributed with ICC), by comparison, can separately compute sin and cos in less than 100 cycles, using a software implementation that uses SSE instead of the x87 unit. A similar software implementation that computed both simultaneously could be faster still. – Stephen Canon Apr 21, 2010 at 15:50 3 WebThe IQmath library uses a 32-bit fixed-point signed number (an “int32_t” in C99) as its basic data type. The IQ format of this fixed-point number can range from IQ1 to IQ30, where the IQ format number indicates the number of fractional bits.
