MULS
Multiply, Saturated
Description
Multiply two signed 32-bit integers and put the product into a 32-bit or 64-bit register. The value const9 is sign-
extended before the multiplication is performed. The MULS result is saturated on overflow.
MULD[c], D[a], const9 (RC)
(32 * K9) --> 32 signed
result = D[a] * sign_ext(const9);
D[c] = result[31:0];
MULE[c], D[a], const9 (RC)
(32 * K9) --> 64 signed
result = D[a] * sign_ext(const9);
E[c] = result[63:0];
MULD[c], D[a], D[b] (RR2)
(32 * 32) --> 32 signed
result = D[a] * D[b];
D[c] = result[31:0];
MULE[c], D[a], D[b] (RR2)
(32 * 32) --> 64 signed
result = D[a] * D[b];
E[c] = result[63:0];
MULD[a], D[b] (SRR)
(32 * 32) --> 32 signed
Multiply D[a] by D[b] (two signed 32-bit integers) and put the product into D[a].
