Abstract
A queue manager manages multiple interfaces among a network, a host bus and a storage means including multiple circular FIFO's in a data communication system handling packet and multimedia data transferred, in either direction, between the host bus and the network. The queue manager includes a programmable parameter RAM interface, computation logic and status means. An efficient queue management algorithm dynamically manages storage of data in the circular multiple FIFO's as data is transferred, in either direction, between the host bus and the network. System bandwidth is allocated by the queue manager to the queues which have the most activity thereby improving the speed of transferring data while reducing the amount of bandwidth that would otherwise be required by prior systems. The programmable interface permits a user to define and dynamically configure the multiple circular FIFO storage means to include other parameters useful in the management of data transferred between the host bus and the network.
