Initialise the kernel's input and output.
The input matrices input0
and input1
must be the output of the kernels: NEGEMMInterleave4x4Kernel and NEGEMMTranspose1xWKernel. These two kernels change the layout of the original matrices to be more cache-friendly.
[in] | input0 | Input tensor containing the interleaved Matrix A. Data type supported: U8/QASYMM8/S8/QASYMM8_SIGNED |
[in] | input1 | Input tensor containing the transposed1xW Matrix B. Data type supported: U8/QASYMM8/S8/QASYMM8_SIGNED/QSYMM8/QSYMM8_PER_CHANNEL |
[out] | output | Output tensor to store the result of matrix multiplication. Data type supported: S32 |
