Abstract
Mobile devices are entering in every sphere of our life. With the introduction of newer features these devices are becoming more and more data centric. Apart from data storage another major concern in such scenarios is data movement. Many protocols exist to aid in data movement within the mobile devices as well as to communicate with the outside world. Among these protocols serial communication protocols are most widely used protocols due to their low pin requirement and ease of implementation. Usually the protocol followed by a device depends on the amount of data that it needs to transfer as well as the speed with which it is required to communicate. But there are situations when a single device has different protocol requirements in two different situations. In such situations a bridge is required such that device can follow communication protocol according to the situational requirement rather than being bound to one kind of protocol.
In this research, a serial protocol bridge has been designed that consists of two most widely used serial protocol controllers . It helps a particular device to communicate with either of the protocol seamlessly. The bridge has been designed using UML 10.0 . All the design modules of bridge have been coded in VHDL and simulated using ModelSim Altera 6.5e. Further these modules were compiled for EP4CE115F29C7 FPGA chip on Cyclone IV Altera DE115 board using Quartus II.
