Instruction Modifiers

Modifier Name	Description
.ABS	Take the absolute value. See below this table for code examples.
.ARRAY	Enable texture arrays. See below this table for code examples.
.CLAMP	Clamp is applied after absolute, but before negation. Clamps value to range [+0,1].
.COMPARISON	Enable comparison filtering in TPU.
.DIRECT	Direct DMA instruction, bypassing the main ALU pipeline
.E0	Element selector for operations that operate on types narrower than 32-bit. This will normally be preceded by the data type (f16 etc.). For source, selects the part of the argument that forms an element. For destination, broadcasts the result to these elements of destination. Reads from: bits 0-7.
.E1	Reads from: bits 8-15.
.E2	Reads from: bits 16-23.
.E3	Reads from: bits 24-31.
.F16	Return packed F16 data.
.F32	Return packed F32 data.
.FCNORM	Fixed point texture data, converted to floating point when returned to USC. See below this table for code examples.
.FLR	Take the floor part (before absolute/negate), NaN’s, +/-inf and +/-0.0f are all preserved. See below this table for code examples.
.INTEGER	[U], [V] , [S], [T] and [Q] Sample Data are treated as integers.
[.LODM]	LOD Mode possible values: .BIAS, .REPLACE, or .GRADIENT.
.LP	Low Precision.
.NEG	Negate. See below this table for code examples.
.NNCOORDS	Non Normalised Coordinates.
.ONEMINUS	x = 1 - x
.PPLOD	Per Pixel LOD is enabled - only valid when LODM = Bias or Replace.
.PROJ	Per Pixel LOD is enabled - only valid when LODM = Bias or Replace
.ROUNDZERO	Round value to zero.
.SAT	Saturate iterated coordinates to 0.0..1.0. See below this table for code examples.
[.SBMode]	Sample Bypass Mode possible values: .DATA, .INFO, or .BOTH. See below this table for code examples.
.SNO	Sample Number is supplied.
.SOO	Sample Offset is supplied. See below this table for code examples.
.TAO	Texture Address Override.
[.type]	Data type possible values: .F32, .U16, .S16, .U8, .S8, .U32, or .S32.
.ZABS	Absolute modifier for the toF16 operand of the Z term.
.ZCLAMP	Clamp bit for the toF16 operand of the Z term.

.ABS code example:

void main()
{
  fragmentColor = abs(a);
}

0  : mov ft0, sh0.abs
     mov ft1, sh1.abs
     mov r0, ft0;
     mov r1, ft1;

.ARRAY code example:

uniform highp sampler2DArray sampler;

void main()
{
    fragmentColor = texture(sampler,
                vec3(textureCoordinate, 0.0));
}

3    : smp2d.fcnorm.array drc0, sh4, r1, sh0, _, r0, 4;

.FCNORM code example:

void main()
{
   fragmentColor = texture(sampler,  ntextureCoordinate);
}

0    : (ignorepe)
{
   itrsmp2d.pixel.fcnorm.schedwdf
   r0, 1, drc0, cf4, sh4, sh0, 4,
   cf0,
}

.FLR code example:

void main()
{
    fragmentColor =
       floor(a);
}

0    : fadd ft0, sh0.flr, c0
       fadd ft1, sh1.flr, c0
       mov r0, ft0;
       mov r1, ft1;

.NEG code example:

void main()
{
    fragmentColor = -a;
}

0    : mov ft0, sh0.neg
       mov ft1, sh1.neg
       mov r0, ft0;
       mov r1, ft1;

.SAT code example:

void main()
{
    fragmentColor =
        clamp(a, 0.0, 1.0);
}

0    : fadd.sat ft0, sh0, c0
       fadd.sat ft1, sh1, c0
       mov r0, ft0;
       mov r1, ft1;

.SBMode code example:

uniform highp sampler2DShadow sampler;

{
    fragmentColor = vec4(texture(sampler,
            vec3(textureCoordinate,
            0.0)));
}

void main()
{
   fragmentColor =
     textureOffset(sampler,
     textureCoordinate, ivec2(1, 1));
}

{
  smp2d.fcnorm.soo drc0,
   sh8, r32, sh0, _, r0, 4;
}
