If the contents of data register D[15] are zero, copy the contents of either data register D[b] (instruction format
SRR) or const4 (instruction format SRC) to data register D[a]; otherwise the contents of D[a] is unchanged. The
const4 value is sign-extended to 32-bits.
D[a] = ((D[15] == 0) ? sign_ext(const4) : D[a]);
D[a] = ((D[15] == 0) ? D[b] : D[a]);
C Not set by this instruction.
V Not set by this instruction.
SV Not set by this instruction.
