Method for a universal interface without a predefined protocol

Disclosed is a method for a universal interface (UI) without a predefined protocol. Benefits include improved functionality.

Background

              Hardware designers are concerned with the direct interfacing of two chips. When the engineers have started the design, the marketing people have typically not determined the customer’s requirement for interfaces. Sometimes, the customers have not yet determined their requirements.

              Glue logic is a custom-designed digital circuit that interconnects larger ready-made circuits to make the required device. The glue logic can be made of integrated-circuit macros or custom-programmed circuits.

Description

              The disclosed method is a universal interface (UI) that operates between any two chips without glue programming. The UI module has tow interfaces. The UI internal bus interacts with the internal bus or other modules of a chip. The XYZ bus interacts other chips. The UI module is FPGA based and programmable via any bus of the chip in which the UI module resides.

              The XYZ bus can be defined to support 2.5, 3.3 volts, or more depending on the advance of technologies. It can be classified into a few groups according to the bus width, such as 32, 64, and 128. The bus width can be any reasonable number. A group with a wider bus width is backward compatible with a group with a narrower bus. With the classification, the implementation cost can be reduced. For instance, if a chip only requires an...
