Utility APIs

Detailed Description

Internal APIs for utility operations.

Defines
#define	TIVX_ALIGN(value, align)   ((((value)+((align)-1U))/(align))*(align))
	Macro to align a 'value' to 'align' units.
#define	TIVX_FLOOR(value, align)   (((value)/(align))*(align))
	Macro to floor a 'value' to 'align' units.
#define	TIVX_DEFAULT_STRIDE_Y_ALIGN   (64U)
	Macro to specify default alignment to use for stride in Y-direction. More...
#define	TIVX_TYPE_IS_SCALAR(type)   (((vx_enum)VX_TYPE_INVALID < (type)) && ((type) < (vx_enum)VX_TYPE_SCALAR_MAX))
	Used to determine if a type is a scalar.
#define	TIVX_TYPE_IS_STRUCT(type)   (((type) >= (vx_enum)VX_TYPE_RECTANGLE) && ((type) < (vx_enum)VX_TYPE_KHRONOS_STRUCT_MAX))
	Used to determine if a type is a struct.
#define	TIVX_TYPE_IS_OBJECT(type)   (((type) >= (vx_enum)VX_TYPE_REFERENCE) && ((type) < (vx_enum)VX_TYPE_KHRONOS_OBJECT_END))
	Used to determine if a type is an Khronos defined object.
#define	TIVX_TYPE_IS_TI_OBJECT(type)   (((type) >= (vx_enum)VX_TYPE_VENDOR_OBJECT_START) && ((type) < (vx_enum)VX_TYPE_VENDOR_OBJECT_END))
	Used to determine if a type is TI defined object.
#define	TIVX_MAGIC   (0xFACEC0DEU)
	A magic value to look for and set in references.
#define	TIVX_BAD_MAGIC   (42U)
	A magic value to look for and set in references. Used to indicate a free'ed reference.
#define	VX_CHECK_PARAM(ptr, size, type, align)   ((size == sizeof(type)) && (((vx_size)ptr & align) == 0U))
	A parameter checker for size and alignment.

Enumerations
enum	tivx_type_e
	TIVX defined reference types.

Functions
static void	tivx_uint32_to_uint64 (volatile uint64_t *val, uint32_t h, uint32_t l)
	Macro to convert 2x uint32 to uint64.
static void	tivx_uint64_to_uint32 (uint64_t val, volatile uint32_t *h, volatile uint32_t *l)
	Macro to convert uint64 to 2x uint32.

Macro Definition Documentation

TIVX_DEFAULT_STRIDE_Y_ALIGN

#define TIVX_DEFAULT_STRIDE_Y_ALIGN   (64U)

Macro to specify default alignment to use for stride in Y-direction.

   Video codecs require 64 byte alignment

   Remaining HWA nodes require 16 byte alignment
