CMP.F
Compare Float
Description
This instruction compares the IEEE-754-1985 single-precision floating-point operands and asserts bits in the
result if their associated condition is true:
bit [0] D[a] < D[b]
bit [1] D[a] == D[b]
bit [2] D[a] > D[b]
bit [3] Unordered
bit [4] D[a] is denormal
bit [5] D[b] is denormal
bits[31:06] are cleared.
The ‘unordered’ bit is asserted if either operand is a NaN.
Note:CMP.F is the only FPU instruction that does not substitute denormal operands for zero before computation.
CMP.FD[c], D[a], D[b] (RR)
D[c][0] = ieee754_lt(D[a], D[b]);
D[c][1] = ieee754_eq(D[a], D[b]);
D[c][2] = ieee754_gt(D[a], D[b]);
D[c][3] = (is_nan(D[a]) OR is_nan(D[b]));
D[c][4] = is_denorm(D[a]);
D[c][5] = is_denorm(D[b]);
Exception Flags
