CVTTPD2PI
Usage: CVTTPD2PI dest,src Modifies flags: None
Converts two packed double-precision floating-point values in the 'src' operand to two packed signed doubleword integers in the 'dest' operand.
Packed Double-Precision FP to Packed Signed INT32 Conversion with Truncation
CVTTPD2PI mm,xmm/mem128 ; 66 0F 2C /r [WILLAMETTE,SSE2]
CVTTPD2PI converts two packed double-precision FP values in the source operand to two packed single-precision FP values in the destination operand. If the result is inexact, it is truncated (rounded toward zero).
The destination operand is an MMX register. The source can be either an XMM register or a 128-bit memory location. For more details , see the Intel Processor manuals.
Example:
cvttpd2pi xmm1 xmm2
