Field Documentation

visionParams

IVISION_Params TIDL_CreateParams::visionParams

Common parameters for all ivision based modules

currLayersGroupId

int32_t TIDL_CreateParams::currLayersGroupId

Group ID of the each layer

isInbufsPaded

int32_t TIDL_CreateParams::isInbufsPaded

Indicates Whether the input buffers are padded or Not.

optimiseExtMem

int32_t TIDL_CreateParams::optimiseExtMem

Optimization level for External memory used bu TIDL

quantRangeExpansionFactor

float32_tidl TIDL_CreateParams::quantRangeExpansionFactor

Expansion factor used for range of activation while quantization

quantRangeUpdateFactor

float32_tidl TIDL_CreateParams::quantRangeUpdateFactor

Update factor used for range of activation while quantization

traceLogLevel

int32_t TIDL_CreateParams::traceLogLevel

Level for debug messages

traceWriteLevel

int32_t TIDL_CreateParams::traceWriteLevel

Level for debug trace dumps of tensors and other data buffers

reservedCtrl

int32_t TIDL_CreateParams::reservedCtrl

Reserved control for debug

flowCtrl

int32_t TIDL_CreateParams::flowCtrl

control for selecting different flows. Applicable only for advanced user

maxPreEmptDelay

float32_tidl TIDL_CreateParams::maxPreEmptDelay

Maximum Tolerated delay for TIDL pre-emption in milliSecond, The delay is assuming C7x processor frequency as 1GHz. If the clocked frequency is different then this variable should be scaled up/down appropriately. Example : to achieve pre-emption within 3 ms (wall clock delay): CPU clocked frequency: 1000 MHz, then maxPreEmptDelay = 3 CPU clocked frequency: 2000 MHz, then maxPreEmptDelay = 6 CPU clocked frequency: 500 MHz, then maxPreEmptDelay = 1.5

traceBaseName

void* TIDL_CreateParams::traceBaseName

trace files base Name

udmaDrvObj

void* TIDL_CreateParams::udmaDrvObj

UDMA driver object pointer . Note : All the addresses given to TIDL are assumed to be virtual addresses. If udma driver is initialized with virtual to physical function pointer initPrms.virtToPhyFxn then the same function will be used for this conversion in TIDL whereever it is needed.

net

sTIDL_Network_t* TIDL_CreateParams::net

Pointer to TILD Model/Network

pFxnLock

TIDL_Lock_t TIDL_CreateParams::pFxnLock

Call back Function pointer to lock critical section/interrupts

pFxnUnLock

TIDL_Unlock_t TIDL_CreateParams::pFxnUnLock

Call back Function pointer to unlock critical section/interrupts

TIDLVprintf

int32_t(* TIDL_CreateParams::TIDLVprintf) (const char *format, va_list arg)

Call back Function pointer to Write Log

tracePtr

void* TIDL_CreateParams::tracePtr

Trace buffer pointer to write trace buffers when TIDL running in multiple instances

TIDLWriteBinToFile

int32_t(* TIDL_CreateParams::TIDLWriteBinToFile) (const char *fileName, void *addr, int32_t size, void *tracePtr)

Call back Function pointer to Write Binary data to a file

TIDLReadBinFromFile

int32_t(* TIDL_CreateParams::TIDLReadBinFromFile) (const char *fileName, void *addr, int32_t size)

Call back Function pointer to read data from a binary file

TIDL_CustomLayerProcess

int32_t(* TIDL_CreateParams::TIDL_CustomLayerProcess) (void *tidlHandle, sTIDL_Layer_t *tidlLayer, void *inPtrs[], void *outPtrs[], void *params, void *dmaUtilsContext, const sTIDL_sysMemHandle_t sysMems[TIDL_SYSMEM_MAX], int32_t execMode)

Custom Layer Process API.

Parameters

tidlHandle	Pointer to the tidlHandle.
tidlLayer	TIDL layer parameters. Refer sTIDL_Layer_t for details.
inPtrs	Input buffers to custom layer.
outPtrs	Output buffers from custom layer.
params	Custom layer parameters.
dmaUtilsContext	Pointer to DMA Utils Handle. Current TIDL initializes 12 DMA channels and same can be used by custom layer
sysMems	System Memory Handle.
execMode	Execution mode of custom layer process API. Refer eTIDL_CustomLayerExecMode for details.

Returns
