System and method for coordinating access to a bus

A method for coordinating access to a bus in a system having a source node, a destination node and a bus coordinator, comprising the steps of:

• determining at said source node whether said source node has capacity to receive read data;
• selectively sending a bus request from said source node to said bus coordinator in response to said source node determining that said source node has capacity to receive read data;
• receiving said bus request at said bus coordinator, said bus request identifying a destination node;
• determining at said bus coordinator whether said destination node has capacity to receive said read request;
• in response to a determination that said destination node has said capacity, said bus controller selectively granting control of said bus to said source node to allow said source node to transfer said read request to said destination node;
• depriving said source node of control of said bus using said bus coordinator after said read request is transferred;
• receiving a response request at said bus coordinator from said destination node;
• and
• in response to receiving said response request, said bus coordinator selectively granting control of said bus to said destination node to allow said destination node to transfer read data to said source node.
