    • A novel processor architecture and algorithms are provided which improve non-volatile memory updates and increases processor performance in successive generations of processors. A new processor architecture is supported by a software model consisting of two new firmware layers and the legacy 32 bit basic input output system (BIOS) firmware. The new firmware layers consist of a Processor Abstraction Layer (PAL) and a System Abstraction Layer (SAL). The PAL and SAL have procedure calls which allow updates of the firmware components in the non-volatile memory of a system, e.g. non-volatile ROM. The present invention includes invoking a system abstraction layer update procedure to implement a new input binary into the non-volatile memory. An algorithm for the non-volatile memory includes selecting a lead processor to perform an update and using the system abstraction layer update procedure. The system abstraction layer update procedure is used to call an appropriate authentication routine. The system abstraction layer update procedure is used to call a specific non-volatile memory implementation routine.
    • 提供了一种新颖的处理器架构和算法,其改进了非易失性存储器更新并且在连续几代处理器中提高了处理器性能。 由两个新固件层和传统32位基本输入输出系统(BIOS)固件组成的软件模型支持新的处理器架构。 新的固件层由处理器抽象层(PAL)和系统抽象层(SAL)组成。 PAL和SAL具有允许更新系统的非易失性存储器中的固件组件的过程调用,例如, 非易失性ROM。本发明包括调用系统抽象层更新过程以将新的输入二进制文件实现到非易失性存储器中。 用于非易失性存储器的算法包括选择引导处理器来执行更新并使用系统抽象层更新过程。 系统抽象层更新过程用于调用适当的认证例程。 系统抽象层更新过程用于调用特定的非易失性存储器实现例程。
