Latest Patents
One of Zengli Duan's latest patents is focused on a virtual one-time programming (OTP) method designed to avoid dead chips during OTP device programming. This innovation addresses the issue of OTP devices not being enabled for a system on chip (SoC). The process involves authenticating the RAMBOOT bootup using a key or key hash from the OTP, determining whether the bootup has been authenticated, and initiating the necessary steps based on the authentication status. The content of the virtual OTP is verified and can be transferred to the OTP hardware module, enabling an authenticated RAMBOOT bootup.
Another significant patent by Duan involves methods and systems for improved partitioning and virtualization in a multi-host environment. This invention allows multiple devices, including CPUs and peripherals, to be associated with a shared memory that is logically partitioned into multiple domains. A single shared virtual map module (VMM) is utilized to map memory access requests to the appropriate partitioned domain based on the originating device's identifier and the type of memory access. This innovation enhances the efficiency of memory access in complex systems.
