 The code of most PSA APIs is expected to match precisely the above layout. However, it is likely that the code structure of some APIs will be more complicated with several calls to the driver interface, mainly to encompass a larger variety of hardware designs. For example, to encompass hardware accelerators that are capable of verifying a MAC and those that are only capable of computing a MAC, the psa_mac_verify() API could call first psa_driver_wrapper_mac_verify() and then fallback to psa_driver_wrapper_mac_compute().
 
-The implementations of `psa_driver_wrapper_<entry_point>` functions are generated by the build system based on the JSON driver description files of the various PSA drivers making up the Mbed TLS PSA Cryptography API implementation. The implementations are splited into two parts. The static ones are generated in a psa_crypto_driver_wrappers.h head file, the non-static ones are generated in a psa_crypto_driver_wrappers_no_static.c C file and the function prototypes declared in a psa_crypto_driver_wrappers_no_static.h header file.

 The psa_driver_wrapper_<entry_point>() functions dispatch cryptographic operations to accelerator drivers, secure element drivers as well as to the software implementations of cryptographic operations.
