There's an IEEE-compliant floating point simulator in the Alpha code base. However, it only implements what Alpha required, in particular: - No gradual underflow. - No 80b floating point (not needed to produce IEEE accurate results for single- and double-precision). You might find John

Hello everyone, I would like to solicit some advice from the group, especially from those with more experience writing simulators. I have recently started toying with a simulation of the AT 3B2/400 Math Acceleration Unit (the WE32106 MAU). This was an optional co-processor that could be
