Computer system including an enhanced communication interface for an ACPI-compliant controller |
摘要 |
A conventional keyboard-style ACPI interface is greatly enhanced by the inclusion of a bi-directional hardware buffer and a special software protocol that allows multiple byte command and data messages to be sent in a burst fashion. The illustrative enhanced ACPI interface alleviates congestion in data transmission that results from the overhead incurred by transferring messages using multiple interrupts per message. An extended embedded controller includes a buffer for temporary storage of a plurality of data bytes and a program code for controlling data transfers to and from the buffer using a data handling technique that is ACPI-compliant.
