AEWB Kernels

Introduction

The list of kernels supported in hwa module.

Each kernel listed here can be used with the vxGetKernelByName call. When programming the parameters, use

• VX_INPUT for [in]
• VX_OUTPUT for [out]
• VX_BIDIRECTIONAL for [in,out]

When programming the parameters, use

• VX_TYPE_IMAGE for a vx_image in the size field of vxGetParameterByIndex or vxSetParameterByIndex
• VX_TYPE_ARRAY for a vx_array in the size field of vxGetParameterByIndex or vxSetParameterByIndex
• or other appropriate types in vx_type_e.
