Unsigned sum of products of unsigned bytes
SYNTAX
FUNCTION
DESCRIPTION
bytes of rsrc1 and rsrc2; the four products are summed, and the result is written to rdest. All values are considered
unsigned. All computations are performed without loss of precision.
modification of the destination register. If the LSB of rguard is 1, rdest is written; otherwise, rdest is not changed.
EXAMPLES
r70 = 0x0afb14f6, r30 = 0x0a0a1414
r10 = 0, r70 = 0x0afb14f6, r30 = 0x0a0a1414
r20 = 1, r80 = 0x649c649c, r40 = 0x9c649c64
r50 = 0x80808080, r60 = 0xffffffff
