versatile pc fpga based verification fast prototyping platform with multimedia applications
IEEE Transactions on Instrumentation and Measurement, 2007Co-Authors: Chung-ping Young, A.w.y. SuAbstract:For most integrated circuit (IC) design houses, building a dedicated field-programmable gate array (FPGA) verification board before the chip is tapped out is usually a requirement. The time and money spent on such boards are usually high. A versatile verification/fast prototyping platform consisting of an FPGA board and the associated System Software is presented. The FPGA board is connected to the host computer through a peripheral component interconnect interface. The System Software running on a Microsoft Windows environment is developed so that all the real-time data that were generated during the verification process can be downloaded and displayed on the host computer. Hence, the system acts like a Logic Analyzer with very large storage memory. Furthermore, the software provides interfaces for personal computer peripherals, such as a Universal Serial Bus camera, a computer monitor, and a soundcard, if the test data for multimedia applications are necessary. The results can be also demonstrated in real time through these devices. Because multimedia data are usually complicated, and the size is huge, the design and thorough verification are usually difficult and take lots of time. The proposed system is both versatile and convenient to use, and verification of designs becomes much easier. An MPEG-4 Simple Profile Video Encoder and a 3-D surround sound processor were realized with the proposed system. Both cases can run in real time. In this paper, the highly complicated H.264/Advanced Video Coding I-Frame encoder is also used to demonstrate the proposed system.

implementation of the cosine law for location awareness system
Asia Pacific Conference on Postgraduate Research in Microelectronics and Electronics, 2010Co-Authors: Yengchang Huang, Yujung HuangAbstract:A proposed UHF RFID location system, based on a known location of the reference tags by applying the cosine theorem to calculus more location information, can provide location-aware services. In this article, the trigonometric cosine and sine functions required in the computation of the law of the cosines are realized using a Coordinate Rotation Digital Computer (CORDIC) based floating-point arithmetic scheme. The implementation of a CORDIC processor based on the IEEE 754 standard for binary floating-point arithmetic is demonstrated. The cosine law is implemented on DE2 circuit board and verified by Logic Analyzer.

design and characterization of parallel prefix adders using fpgas
Southeastern Symposium on System Theory, 2011Co-Authors: David H K Hoe, Chris D Martinez, Sri Jyothsna VundavalliAbstract:Parallel-prefix adders (also known as carry-tree adders) are known to have the best performance in VLSI designs. However, this performance advantage does not translate directly into FPGA implementations due to constraints on Logic block configurations and routing overhead. This paper investigates three types of carry-tree adders (the Kogge-Stone, sparse Kogge-Stone, and spanning tree adder) and compares them to the simple Ripple Carry Adder (RCA) and Carry Skip Adder (CSA). These designs of varied bit-widths were implemented on a Xilinx Spartan 3E FPGA and delay measurements were made with a high-performance Logic Analyzer. Due to the presence of a fast carry-chain, the RCA designs exhibit better delay performance up to 128 bits. The carry-tree adders are expected to have a speed advantage over the RCA as bit widths approach 256.
