Data Structures
struct	SDL_ROM_Checksum_obj
	This structure is used to store the resultant value of ROM Checksum. More...

Functions
void	SDL_ROM_Checksum_init (SDL_ROM_Checksum_obj *const md)
	This API will Initialize the buffer where hash value to be stored. More...
int32_t	SDL_ROM_Checksum_process (SDL_ROM_Checksum_obj *md, uint8_t *in, uint32_t inlen)
	This API is used to process the ROM region data. More...
void	SDL_ROM_Checksum_compress (SDL_ROM_Checksum_obj *md, uint8_t *buf)
	This API is used to compress the data of ROM region and store the result in md->state. More...
int32_t	SDL_ROM_Checksum_done (SDL_ROM_Checksum_obj *md)
	This API will increase our data length with the help of padding ( because our algorithm can compress only 1024-bit length of data at a time) and will compress then will store final has value in md->state. More...
int32_t	SDL_ROM_Checksum_compareResult (uint64_t buflen, SDL_ROM_Checksum_obj *md, uint64_t *golden_value)
	This API will compare the resultant hash value of golden value. More...
void	SDL_memcpy (void *dest, void *src, uint32_t n)
	This API will copy source pointer data to destination pointer. More...
