Patent ID: 7571266

Claim:
In a computerized system (i) which includes an interface for connection with a peripheral device and (ii) which is incapable of dynamically extending bus cycle timing if required by the peripheral device in order to carry out a particular current operation, a method comprising: (a) providing within said system a given peripheral device which requires an extension of bus cycle timing in order to carry out properly the current operation in cooperation with said computerized system, said given peripheral device being configured to generate a specific signal when said extension is required in order to complete carrying out the current operation; and (b) connecting said given peripheral device with the interface of said computerized system such that an output on said given peripheral device for sending said specific signal is connected to an interrupt input of said interface and configuring said system in a way which causes the system (i) to recognize said specific signal through the interrupt input when said specific signal is generated and (ii) to instruct the given peripheral device to retry carrying out the current operation in response to the presence of said specific signal.
