CupvaSamplerInput2D

Defined in src/device/vpu_runtime/include/cupva_device/sampler.h

struct CupvaSamplerInput2D

Configure a 2D input buffer for sampling.

This structure should be used to pass parameters to one of the cupvaSamplerInit() overloads. Where a field is specified as optional, a default value may be used by leaving the relevant entry zero/default initialized.

Public Members

void const *data

Pointer to input data table

CupvaSamplerInputType type

Pixel format of lookup table entries

uint32_t width

Number of valid entries in the input table, x dimension

uint32_t height

Number of valid entries in the input table, y dimension

uint32_t linePitch

Line pitch in pixels-> Optional, defaults to width

ptrdiff_t inputAdv

The input table base pointer can move every iteration of dim2 or patch. This parameter specifies the offset to the next input table in pixels. Optional, defaults to zero.

CupvaSamplerTaskOutOfRangeHandlingMode outOfRangeMode

Specify how to handle lookups to this table which result in out-of-range accesses. Optional, defaults to SAMPLER_OUT_OF_RANGE_CONSTANT.

uint32_t outOfRangeVal

If outOfRangeMode is SAMPLER_OUT_OF_RANGE_CONSTANT, this specifies the constant value to use. Otherwise, it is ignored. Optional, defaults to zero.

uint32_t flags

Optional flags field. See CupvaSamplerInput2DFlags for valid flag values which can be combined with bitwise OR
