GE
Greater Than or Equal
GE.U
Greater Than or Equal Unsigned
Description
If the contents of data register D[a] are greater than or equal to the contents of either data register D[b] (instruction
format RR) or const9 (instruction format RC), set the least-significant bit of D[c] to one and clear the remaining bits
to zero; otherwise clear all bits in D[c]. D[a] and D[b] are treated as 32-bit signed (GE) or unsigned (GE.U) integers.
The const9 value is sign-extended (GE) or zero-extended (GE.U).
GED[c], D[a], const9 (RC)
result = (D[a] >= sign_ext(const9));
D[c] = zero_ext(result);
GED[c], D[a], D[b] (RR)
result = (D[a] >= D[b]);
D[c] = zero_ext(result);
GE.UD[c], D[a], const9 (RC)
result = (D[a] >= zero_ext(const9)); // unsigned
D[c] = zero_ext(result);
GE.UD[c], D[a], D[b] (RR)
result = (D[a] >= D[b]); // unsigned
D[c] = zero_ext(result);
