Abstract
A system and method for controlling communications between a plurality of clients and a central component. An embodiment of the invention includes one or more buses that connect the clients and the central component. This embodiment also includes a control module that is configured to receive ASK messages from the clients and issue GO commands to the clients. Each ASK message represents a request from a client to access the central component. Each GO command to the client represents permission for that client to access the central component. The control module comprises delay stages that delay the GO command. The delays may be different from client to client. The number of delay stages is chosen so that for all clients, the delay between the issuance of a GO command and the receipt at the central component of communications from the clients is the same.
