Mantissa to Integer
Extract the mantissa and sign from the IEEE 32-bit floating-point number in the source register, and create a signed integer in the destination register. The most significant bit is bit 32, but it is sign extended.
Code/Case: 55
Flags
Z – set if the result is zero
N – set if the result is negative
C – not defined
Register Usage
Cycle 1: Source register read
Cycle 3: Destination register write
