SAM4E [DATASHEET]

Atmel-11157D-ATARM-SAM4E16-SAM4E8-Datasheet_12-Jun-14

Converts between a half-precision value and a single-precision value.

Syntax

VCVT{y}{cond}.F32.F16 Sd, Sm

VCVT{y}{cond}.F16.F32 Sd, Sm

where:

y

Specifies which half of the operand register Sm or destination register Sd is used for the
operand or destination:

- If y is B, then the bottom half, bits [15:0], of Sm or Sd is used.
- If y is T, then the top half, bits [31:16], of Sm or Sd is used.

cond

is an optional condition code, see 

.

Sd

is the destination register.

Sm

is the operand register.

Operation

This instruction with the

.F16.32

 suffix: 

1.

Converts the half-precision value in the top or bottom half of a single-precision. register to single-precision.

2.

Writes the result to a single-precision register.

This instruction with the.F32.F16 suffix:

1.

Converts the value in a single-precision register to half-precision.

2.

Writes the result into the top or bottom half of a single-precision register, preserving the other half of the 
target register.

Restrictions

There are no restrictions.

Condition Flags

These instructions do not change the flags.
