The older (68030) machine has slower floating-point performance compared to its integer arithmetic
A previous old, as well as a recent new article in the Communications have discussed such implementations: Payne, Rabung and Bogyo  for IBM 360s in 1969 and Carta in 1990  for unspecified CPU's that seem to do integer arithmetic
with 31-bit registers, a variety unknown to us.
There is also an integer arithmetic
requirement in this implementation of the minimal standard.
15 respectively (that can be represented in two's-complement 32-bit and 16-bit integer arithmetic
The Pentium 4 processor integrates the new Intel SSE2 instruction set including 144 new instructions for 128-bit Single Instruction Multiple Data (SIMD) integer arithmetic
and 128-bit SIMD double-precision floating point.
including 128-bit SIMD integer arithmetic
and 128-bit SIMD
With its 200-MHz superscalar CPU core capable of two simultaneous integer instructions, the device can perform integer arithmetic
operations at a rate of 420 MIPS, the highest level in its class.
