Finally, the proposed system will simulated and implemented on FPGA board and experimental outcomes shows the better efficiency in single error correction and detection of double errors.įPGA based solutions become more common in embedded systems these days. Thus in this methodology, have introduced a UART-SEC-DED communication module design which utilizes the Hamming encoder and decoders to achieve the forward error correction. The correction of forward errors is a mechanism to handle and rectify those errors (i.e. These kinds of signal errors are named as forward-errors. Though, UART is a type of shorter range communication still they are not resistant to noisy channel which leads to communication errors by flipping or loosing of bits. It is a shorter range communication protocol, which able to perform half-duplex and full-duplex type of communication at baud rates. The Universal Asynchronous Receiver Transmitter (UART) is the very simple and significant sequential communication protocol which is basically utilized for microprocessors & microcontroller systems.

The experimental results were obtained on a real-world system and we also make available the PC software test application that is used for performance assessment to allow for reproduction of our results. A comparison with related work on UDP/IP core implementations shows that our implementation is significantly more efficient in terms of resource utilization and performance. The UDP/IP core is available as open-source code. Furthermore, this property also allows for initiating packet transmission immediately, i.e., the UDP/IP core can start a transmission without the requirement of receiving, storing, and processing user data beforehand. An observation regarding the internet checksum algorithm, allows us to reduce the hardware requirements for computing the checksum. To this end, we present the design of an efficient UDP/IP core for PC-FPGA communication that has been designed to occupy a minimum amount of hardware resources on the FPGA. While PCI Express represents the currently fastest and most expensive solution to connect a FPGA to a general purpose CPU, there exist several applications with I/O requirements for which Gigabit Ethernet is sufficient. Input/Output (I/O) speeds can become a bottleneck and directly affect the performance of a reconfigurable accelerator since the chip will idle when there are no data available. As FPGAs become larger and more powerful, they are increasingly used as accelerator devices for compute-intensive functions.
