Member Function Documentation

◆ configure() [1/2]

void configure ( const ICLTensor input,
ICLTensor output 
)

Initialize the function.

Parameters
[in]inputInput tensor. Data types supported: F16/F32.
[out]outputOutput tensor. Data types supported: same as input.

Definition at line 133 of file CLElementWiseUnaryLayer.cpp.

References CLKernelLibrary::get().

134 {
135  configure(CLKernelLibrary::get().get_compile_context(), input, output);
136 }
static CLKernelLibrary & get()
Access the KernelLibrary singleton.
void configure(const ICLTensor *input, ICLTensor *output)
Initialize the function.

◆ configure() [2/2]

void configure ( const CLCompileContext compile_context,
const ICLTensor input,
ICLTensor output 
)

Initialize the function.

Parameters
[in]compile_contextThe compile context to be used.
[in]inputInput tensor. Data types supported: F16/F32.
[out]outputOutput tensor. Data types supported: same as input.

139 {
140  _impl->src = input;
141  _impl->dst = output;
142  _impl->op = std::make_unique<opencl::ClNeg>();
143  _impl->op->configure(compile_context, input->info(), output->info());
144 }

◆ operator=() [1/2]

CLNegLayer& operator= ( const CLNegLayer )
delete

Prevent instances of this class from being copied (As this class contains pointers)

Referenced by CLNegLayer::CLNegLayer().

◆ operator=() [2/2]

CLNegLayer & operator= ( CLNegLayer &&  )
default

Default move assignment operator.

◆ run()

void run ( )
overridevirtual

Run the kernels contained in the function.

For Neon kernels:

  • Multi-threading is used for the kernels which are parallelisable.
  • By default std::thread::hardware_concurrency() threads are used.
Note
CPPScheduler::set_num_threads() can be used to manually set the number of threads

For OpenCL kernels:

  • All the kernels are enqueued on the queue associated with CLScheduler.
  • The queue is then flushed.
Note
The function will not block until the kernels are executed. It is the user's responsibility to wait.
Will call prepare() on first run if hasn't been done

Implements IFunction.

◆ validate()

Status validate ( const ITensorInfo input,
const ITensorInfo output 
)
static

Static function to check if given info will lead to a valid configuration of CLNegLayer.

Parameters
[in]inputFirst tensor input info. Data types supported: F16/F32.
[in]outputOutput tensor info. Data types supported: Same as input.
Returns
a status
