Function Usage

Sets the configuration related to real-time format conversion (from NZ to ND) during the DataCopy (CO1 -> GM and CO1 -> A1) process.

Prototype

__aicore__ inline void SetFixpipeNz2ndFlag(uint16_t ndNum, uint16_t srcNdStride, uint16_t dstNdStride)
// The following prototype is supported only by the Atlas 350 Accelerator Card.
__aicore__ inline void SetFixpipeNz2ndFlag(uint16_t ndNum, uint16_t srcNdStride, uint32_t dstNdStride)

Parameters

**Table 1** Parameters
Parameter	Input/Output	Description
ndNum	Input	Number of NDs. The type is uint16_t. Value range: ndNum ∈ [1, 65535].
srcNdStride	Input	Source stride in fractal size, indicating head-to-head stride between adjacent source NZ matrices. Atlas A2 training product/Atlas A2 inference product: srcNdStride ∈ [1, 512] (unit: fractal_size 1024 bytes) Atlas A3 training product/Atlas A3 inference product: srcNdStride ∈ [1, 512] (unit: fractal_size 1024 bytes) Atlas 200I/500 A2 inference product: srcNdStride ∈ [1, 512] (unit: fractal_size 1024 bytes) Atlas 350 Accelerator Card: srcNdStride ∈ [0, 65535] (unit: C0_SIZE)
dstNdStride	Input	Head-to-head stride between adjacent destination ND matrices. The unit is element. Atlas A2 training product/Atlas A2 inference product: dstNdStride ∈ [1, 65535] Atlas A3 training product/Atlas A3 inference product: dstNdStride ∈ [1, 65535] Atlas 200I/500 A2 inference product: dstNdStride ∈ [1, 65535] Atlas 350 Accelerator Card: dstNdStride ∈ [1, 2³² – 1]
