Default Constructor.

Prevent instances of this class from being copied (As this class contains pointers)
|
default |
Allow instances of this class to be moved.

) |
Initialise the kernel's input and output.
The input matrices input0
and input1
must be the output of the kernels: CLGEMMInterleave4x4Kernel and CLGEMMTranspose1xWKernel. 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 types supported: U8 |
[in] | input1 | Input tensor containing the transposed Matrix B. Data types supported: same as input0 |
[out] | output | Output tensor to store the result of matrix multiplication, Data types supported: same as input0 |
[in] | a_offset | Offset to be added to each element of the matrix A. |
[in] | b_offset | Offset to be added to each element of the matrix B. |
[in] | output_offset | Offset to be added to each element of the output matrix |
[in] | output_mult_int | Offset to be added to each element of the output matrix |
[in] | shift | Number of bits to shift right the result. |
|
delete |
Prevent instances of this class from being copied (As this class contains pointers)
|
default |
Allow instances of this class to be moved.
|
overridevirtual |
Enqueue the OpenCL kernel to process the given window on the passed OpenCL command queue.
[in] | window | Region on which to execute the kernel. (Must be a valid region of the window returned by window()). |
[in,out] | queue | Command queue on which to enqueue the kernel. |
Implements ICLKernel.
