Field-programmable gate array (FPGA) technology The FPGA is a circuit that is designed in a way that a customer buying it, is the one that will configure it. In other cases, the designer can configure it after the manufacturing processes. This is the reason behind its name, field-programmable gate array (FPGA). This device is widely used in the digital electronic circuits due to its performance and the reliability in data conveyer and process analysis. It is also used in logic circuits. The logic blocks of the device may consist anything from, memory, logic gates or even anything that is almost an element fit enough to be integrated in the circuit. An embedded system is a very important system that has a special role in the computer making it completely in control of any device. The FPGAs are parallel to nature as compared to the processors. The reason behind is that the processes are of different operations and they are not forced to complete for the same resources. An FPGA chip adoption is driven by the fact that combined FPGAs provide the best ASICs parts and processor-based systems with this device are equally the best in performance and reliability. The importance of the FPGA is its providence of reliability and hardware-timed speed. The device do not need high volumes to justify any huge upfront expense of custom ASCI design. Below is an internal structure of an FPGA. Fig. 1. Internal Structure of an FPGA system. The 5 general benefits of the FPGA are its high performance. This takes the advantage it has on the hardware parallelism and is more reliable that the digital signal processors. The time to market of the FPGA is also another benefit as it is flexible and has a wide range of functionalities. You can then implement incremental changes and literate on an FPGA design within hours instead of weeks. The device is cost effective and reliable as it involves several layers of abstraction to aid in scheduling tasks and share resources.

Background Information on UART in Xilinx There are different types of UARTs in existence today. They all differ from each other based on their wide range of quality receivership and transmitting processes. A Universal Asynchronous Receiver / Transmitter is a device that is put in microcontrollers. The device is designed to be used in different types of applications that are ranged in digital electric circuits. A UART are found in the computer motherboards and are very essential in processes that are performed in the computer, especially during data receivership and transmission. The UARTs are commonly used in the modems, wireless communication systems platforms such as Bluetooth modules, and GPS units, among other digital applications. In Xilinx, the UART is connected to an AMBA AXI. This type is called the LogiCORE™ IP AXI Universal Asynchronous Receiver Transmitter (UART) 16550. It is connected to an Advance Microcontroller Bus Architecture (AMBA®) AXI. Its purpose is to provide a controller interface that is used in asynchronous serial data transfer. This processes occur in computers.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
