     * **hipify-perl** : Script based tool to convert CUDA code to portable CPP. Converts CUDA APIs and kernel builtins.

 ### Identifying HIP Target Platform
 All HIP projects target either AMD or NVIDIA platform. The platform affects which headers are included and which libraries are used for linking.
 
-- `HIP_PLATFORM_HCC` is defined if the HIP platform targets AMD
+- `HIP_PLATFORM_AMD` is defined if the HIP platform targets AMD
 
-- `HIP_PLATFORM_NVCC` is defined if the HIP platform targets NVIDIA
+- `HIP_PLATFORM_NVIDA` is defined if the HIP platform targets NVIDIA
 
 ### Identifying the Compiler: hip-clang or nvcc
 Often, it's useful to know whether the underlying compiler is HIP-Clang or nvcc. This knowledge can guard platform-specific code or aid in platform-specific performance tuning.

 The hip_runtime.h and hip_runtime_api.h files define the types, functions and enumerations needed to compile a HIP program:
 
 - hip_runtime_api.h: defines all the HIP runtime APIs (e.g., hipMalloc) and the types required to call them. A source file that is only calling HIP APIs but neither defines nor launches any kernels can include hip_runtime_api.h. hip_runtime_api.h uses no custom hc language features and can be compiled using a standard C++ compiler.
-- hip_runtime.h: included in hip_runtime_api.h. It additionally provides the types and defines required to create and launch kernels. hip_runtime.h does use custom hc language features, but they are guarded by ifdef checks. It can be compiled using a standard C++ compiler but will expose a subset of the available functions.
+- hip_runtime.h: included in hip_runtime_api.h. It additionally provides the types and defines required to create and launch kernels. hip_runtime.h can be compiled using a standard C++ compiler but will expose a subset of the available functions.
 
 CUDA has slightly different contents for these two files. In some cases you may need to convert hipified code to include the richer hip_runtime.h instead of hip_runtime_api.h.
