Access the scheduler singleton.
void free(void *ptr) override
Interface to be implemented by the child class to free the allocated tensor.
#define ARM_COMPUTE_ERROR_ON(cond)
If the condition is true then an error message is printed and an exception thrown.
Definition: Error.h:466
std::unique_ptr< IMemoryRegion > make_region(size_t size, size_t alignment) override
Create self-managed memory region.
Copyright (c) 2017-2022 Arm Limited.
Interface to enqueue OpenCL kernels and get/set the OpenCL CommandQueue and ICLTuner.
void * allocate(size_t size, size_t alignment) override
Interface to be implemented by the child class to allocate bytes.
#define ARM_COMPUTE_UNUSED(...)
To avoid unused variables warnings.
