# AMD RPP Extension

The AMD VX RPP extension (vx_rpp) is an OpenVX module that implements an interface to access RPP functionality as OpenVX kernels. These kernels can be accessed from within OpenVX framework using OpenVX API call [vxLoadKernels](https://www.khronos.org/registry/vx/specs/1.0.1/html/da/d83/group__group__user__kernels.html#gae00b6343fbb0126e3bf0f587b09393a3)(context, "vx_rpp").
