摘要
A method of protecting software for embedded applications against unauthorized access. Software to be protected is loaded into a protected memory area. Access to the protected memory area is controlled by sentinel logic circuitry. The sentinel logic circuitry allows access to the protected memory area from only either within the protected memory area or from outside of the protected memory area but through a dedicated memory location within the protected memory area. The dedicated memory location then points to protected address locations within the protected memory area.
