- Does anybody here know of any microprocessors which did not use any integer
- units or registers, but instead modified the floating point execution units
- to inhibit the normalization pipe stage whenever an "integer" flag within
- the instruction was set.
-
- The idea is to use this feature for a huge savings in area in processors which
- are intended primarilly for FP operation but must still have good integer
- performance.

- Thanks.
