PRODUCT SPECIFICATION

Convert floating-point to unsigned integer using

PCSW rounding mode

[ IF rguard ] ufixieee rsrc1

(unsigned long) ((float)rsrc1)

Function unit

Operation code

Number of operands

Modifier range

operation converts the single-precision IEEE floating-point value in rsrc1to an unsigned integer and

writes the result into rdest Rounding is according to the IEEE rounding mode bits in PCSW. If rsrc1 is denormalized,

zero is substituted before conversion, and the IFZ flag in the PCSW is set. If

causes an IEEE exception,

such as overflow or underflow, the corresponding exception flags in the PCSW are set. The PCSW exception flags are

sticky: the flags can be set as a side-effect of any floating-point operation but can only be reset by an explicit

operation. The update of the PCSW exception flags occurs at the same time as rdest is written. If any

other floating-point compute operations update the PCSW at the same time, the net result in each exception flag is the

logical OR of all simultaneous updates ORed with the existing PCSW value for that exception flag.

ufixieeeflags

operation computes the exception flags that would result from an individual

operation optionally takes a guard, specified in rguard If a guard is present, its LSB controls the

modification of the destination register. If the LSB of rguard is 1, rdest and the exception flags in PCSW are written;

otherwise, rdestis not changed and the operation does not affect the exception flags in PCSW.
