IMPLEMENTATION OF IEEE 802.11A WLAN BASEBAND PROCESSOR

    Due to the low-cost and high-data-rate, the popularity of IEEE 802.11-based Wireless Local Area Networks (WLAN) is growing exponentially. An existing software implementation for a fully-compliant 802.11a full-rate digital base-band transmitter requires the use of a 22- processor array running at a 1.0GHz clock frequency to reach 54Mbits/s performance.Digital signal processors (DSPs) are a special class of processor optimized for signal-processing applications in communication systems.The 802.11a standard operates in the 5GHz band with possible data rates of 6, 9, 12, 18, 24, 36, 48, and 54 Mbits/s. The 802.11g standard released in 2003 operates in the 2.4GHz band and supports all the data rates defined in the 802.11a and 802.11b standards. For the higher data rates in 802.11a, the 802.11g standard uses the same OFDM technology in 802.11a, while backward compatibility is added to support the lower data rates of 802.11b . In this project, a software-based 802.11a digital base-band processor simulated using Verilog HDL implementation.

A VERILOG IMPLEMENTATION OF UART DESIGN WITH BIST CAPABILITY

    A universal asynchronous receiver/transmitter is a type of "asynchronous receiver/transmitter", a piece of computer hardware that translates data between parallel and serial forms. UARTs are commonly used in conjunction with other communication standards such as RS-232. A UART is usually an individual (or part of an) integrated circuit used for serial communications over a computer or peripheral device serial port. UARTs are now commonly included in microcontrollers. A dual UART or DUART combines two UARTs into a single chip. Many modern ICs now come with a UART that can also communicate synchronously; these devices are called USARTs.This project focuses on the design of a UART chip with embedded BIST architecture using Field Programmable Gate Array (FPGA) technology.The problems of Very-Large-Scale-Integrated testing followed by the behaviour of UART circuit using Verilog HDL. In the implementation phase , the BIST technique will be incorporated into the UART design before the overall design is synthesized by means of reconfiguring the existing design to match testability requirements.
