# UQDECP (vector): Unsigned saturating decrement vector by count of true predicate elements

UQDECP Zdn.D, Pm.D (SVE (SME

## 128-bit SVE

Count the non-zero predicate bits corresponding to 64-bit elements from (1), then subtract the total from each 64-bit element from (2), with unsigned saturation to zero, setting (3) to the result.

## 256-bit SVE

Count the non-zero predicate bits corresponding to 64-bit elements from (1), then subtract the total from each 64-bit element from (2), with unsigned saturation to zero, setting (3) to the result.

## 512-bit SVE

Count the non-zero predicate bits corresponding to 64-bit elements from (1), then subtract the total from each 64-bit element from (2), with unsigned saturation to zero, setting (3) to the result.

## Larger sizes

## 1024-bit SVE

Count the non-zero predicate bits corresponding to 64-bit elements from (1), then subtract the total from each 64-bit element from (2), with unsigned saturation to zero, setting (3) to the result.

## 2048-bit SVE

Count the non-zero predicate bits corresponding to 64-bit elements from (1), then subtract the total from each 64-bit element from (2), with unsigned saturation to zero, setting (3) to the result.
