Multiply sources into the destination.
mul vDest, vSrc0, vSrc1
The following code fragment shows the operations performed by the mul instruction to write a result to the destination.
SetDestReg(); SetSrcReg(0); SetSrcReg(1); m_TmpReg.x = m_Source[0].x * m_Source[1].x; m_TmpReg.y = m_Source[0].y * m_Source[1].y; m_TmpReg.z = m_Source[0].z * m_Source[1].z; m_TmpReg.w = m_Source[0].w * m_Source[1].w; WriteResult();
The following example illustrates how the mul instruction might be used.
mul r4, v0, r1
