Abstract: A method for enhancing signal integrity in an interface between a source device and at least one destination device includes: analyzing two or more consecutive data patterns intended to be conveyed by the interface to determine whether data transitions corresponding to the data patterns are likely to introduce coupling noise and/or simultaneous switching output (SSO) effects on the interface; generating a modified data pattern for transmission by the interface, the modified data pattern reducing coupling noise and/or SSO effects on the interface compared to an original data pattern intended to be conveyed by the interface; and transmitting the modified data pattern and information regarding a manner in which the original data pattern was modified to the destination device to thereby reduce coupling noise and/or SSO effects on the interface.

Abstract: Disclosed is a diode clamping circuit that is used in an I/O buffer to suppress noise. Diode-connected CMOS transistors or PN junction transistors are utilized, which are native to the CMOS process. Switching circuitry is also disclosed to isolate the diodes and prevent current drain in the circuit. Switching circuitry is also used to switch between two different power supply voltages.

Abstract: An object oriented interactive application interface for facilitating application program development in a networked computer system providing on-line services is disclosed. The present invention is an Interactive Application Object module (IAO), comprising a client side portion and a server side portion, that facilitates the development of client applications for interaction with a server across a network. The IAO comprises a set of software objects that include interfaces and methods for implementing a client on-line service application at a high abstraction layer. The IAO provides high level objects for use by a client application for handling a large set of interactive system and business functions. On the client device, the IAO insulates the client application from the implementation details of a particular low level network interface.
