The Xilinx FPGA architecture is very regular and gatearray-like, but it is not a simple sea-of-gates. An understanding of the architecture and the resources it provides can make designs become more efficient in both speed and density. This Application Note focuses on the features of the XC4000 architecture and its supporting software that improve design efficiency. It also describes advanced de...

| Recently, a lot of recon gurable systems (RSs) utilizing FPGAs have been reported. The aim is to achieve high performance with low production cost, or to produce non-\von Neumann" machines. In this paper, we overviews RSs. FPGAs, the key components of RSs, are introduced. Second, we categorize RSs into several types. Next, applications are described. Then, hot topics related to RSs are mentio...

This paper presents a new family of architectures for multi-cycle area-efficient evaluation of elementary and composite functions, and an exploration of the design tradeoffs for implementation on Field Programmable Gate Arrays (FPGAs). The method is exemplified with two common functions, sine and power-of-2. To test the performance of each design, we compare the proposed architecture to an esta...

Programmable Active Memories (PAM) are a novel form of universal hardware co-processor. Based on Field-Programmable Gate Array (FPGA) technology, a PAM is a virtual machine, controlled by a standard microprocessor, which can be dynamically configured into a large number of application-specific circuits. PAMs offer a new mixture of hardware performance and software versatility. We review the imp...

Within a project whose objective is to develop a small-size 3D sensor combining a video camera with a 3D laser-based \camera", this paper describes the current status of the laser camera. The prototype of the laser camera is operational and is able to produce 3D \images" with good deenition at high speed. Because of size constraints, some of the control electronics are implemented in an FPGA. T...

This paper gives a brief introduction to the application-dependent FPGA testing. In comparison with the conventional application-independent FPGA testing whose objective is to test the resources of a FPGA chip as exhaustively as possible, application-dependent FPGA testing is only performed on the resources used by a specific application implemented on the FPGA. The multi-configuration strategy...

This paper proposes a new adaptable FPGA logic element based on fracturable 6-LUTs, which fundamentally alters the longstanding belief that a 4-LUT is the most efficient area/delay tradeoff. We will describe theory and benchmarking results showing a 15% performance increase with 12% area decrease vs. a standard BLE4. The ALM structure is one of a number of architectural improvements giving Alte...
