Abstract
Abstract The present invention comprises a method and system for implementing prioritized communications in a computer system. The present invention is implemented on a computer system having a microprocessor and a plurality of peripheral devices coupled to the computer system. The system of the present invention determines a first priority level and determines a second priority level. The system of the present invention receives a bandwidth allocation request from a software process to transfer data at the first priority level between two or more peripheral devices. The system subsequently allocates a first priority data transfer bandwidth between the devices in response to the request and performs a first data transfer between the devices using the first priority data transfer bandwidth. In addition, the system of the present invention performs a second data transfer between other devices using a second priority data transfer bandwidth. The second data transfer occurs at a second priority level. Thus, the system of the present invention ensures the first data transfer at the first priority level is not disturbed by the second data transfer. In this manner, the system of the present invention guarantees the first priority data transfer bandwidth for the software process.
