UART implementation on FPGA Background Information on FPGA An FPGA is a device that contains a medium of reconfigurable gate array logic circuitry. When the FPGA is configured, the internal circuitry is connected in a way that creates a hardware implementation of the software application. Within the digital field, there are 3 basic types of devices which are defined as memory, logic and processors. The recent technological improvement, has made it possible for the FPGAs to be cost effective and reliable. the primary component that makes the FPGA reliable is its flexibility which makes it a wide rage functional composite. Unlike processors, FPGAs use dedicated hardware for processing logic and do not have an operating system. FPGAs are truly parallel in nature so different processing operations do not have to compete for the same resources. As a result, the performance of one part of the application is not affected when additional processing is added. Also, multiple control loops can run on a single FPGA device at different rates. FPGA-based control systems can enforce critical interlock logic and can be designed to prevent I/O forcing by an operator. However, unlike hard-wired printed circuit board (PCB) designs which have fixed hardware resources, FPGA-based systems can literally rewire their internal circuitry to allow reconfiguration after the control system is deployed to the field. FPGA devices deliver the performance and reliability of dedicated hardware circuitry. In an FPGA logic blocks are implemented using multiple level low fan-in gates, which gives it a more compact design compared to an implementation with two-level AND-OR logic.
