Abstract
A data hub for facilitating and effecting data transfers between signal processors with high efficiency is disclosed. The data hub receives low priority data transfer instructions from a master CPU and is capable of transferring such low priority data between processors without imposing significant overhead burdens on either the data source or destination. The hub may have the further capability of asynchronously receiving intermediate priority data transfers, storing the received data and transferring it to a destination unit before any further low priority transfers are effected. The hub may have the further capability of asynchronously receiving high priority transfer requests which are effected by the hub before both intermediate and low priority transfers. The hub may be used as a keystone building block for use in linking signal processors.
