Abstract

The present invention discloses a method of accessing stored information in multi-framed data transmissions, comprising at least one control interface and at least one elastic store, wherein the control interface accesses the elastic store through a mailbox communications method. The control interface accesses the elastic store via the mailbox communications method, which comprises: (a) setting a address for a data location within said elastic store; (b) setting a request to read from, or write to, said data location within said elastic store; (c) issuing a “GO_{——————}” signal to retrieve data information from said data location within said elastic store, by writing said “GO_{——————}” signal to said microprocessor, which causes a circuit to read from said requested data location within said elastic store; (d) waiting for a possible, but not to be expected, de-assertion of a busy signal to be issued from said data location within said elastic store, and then; and then (e) reading back the value of said data information to said control interface. Where a busy signal occurs, the microprocessor must wait and issue a subsequent “GO_{——————}” signal to retrieve the data information from the data location; where a busy signal does not occur the “GO_{——————}” signal causes the circuit to read from the requested data location and send the data information hack to the microprocessor, where the data information is stored in a user-accessible register.
