摘要： An embedded controller includes a microcontroller core, a first bus interface that does not support bus arbitration, a second bus interface and memory control circuitry. The first bus interface is configured to receive and transmit memory transactions from and to a Central Processing Unit (CPU) chipset. The second bus interface is configured to communicate with a memory and to transfer the memory transactions of the CPU chipset to and from the memory. The memory control circuitry is configured to evaluate a starvation condition that identifies an inability of the microcontroller core to access the memory via the second bus interface due to the memory transactions transferred between the CPU chipset and the memory via the first and second bus interfaces, and to invoke a predefined corrective action when the starvation condition is met.

摘要： An improved system is described for allowing an embedded controller and a host processor to share access to modules in a computer system. The shared access system of the present invention enables exclusive, one-at-a-time access by a processor to a module and concurrent access by more than one processor to a module. An internal bus with two power sources is used to allow continued access by one of the processors when one of the two power sources is not providing power. Asynchronous clocking is provided to allow increased throughput to modules. An example of a protocol that allows an embedded controller to access more than one module is also described.
摘要翻译：描述了一种改进的系统，用于允许嵌入式控制器和主处理器共享对计算机系统中的模块的访问。本发明的共享访问系统使得处理器能够对模块进行一次性一次访问，并且由多个处理器对模块的并发访问。当两个电源之一不提供电源时，使用具有两个电源的内部总线来允许其中一个处理器继续访问。提供异步时钟以允许增加模块的吞吐量。还描述了允许嵌入式控制器访问多于一个模块的协议的示例。
