An area-efficient implementation of a fast-converging square-root algorithm is presented. the design of special arithmetic operations differs in many ways from the traditional tasks that digital designers are used to, and the role of parameterizability and mapping of mathematical algorithms onto digital hardware is discussed. Certain real-world applications requiring the use of the square-root operator are presented, and it is argued that implementing special arithmetic operations directly in hardware offers significant speed advantages over the conventional approach of implementing them in software. the mathematical algorithm of the square-root operator is described, and its applicability to an implementation in digital logic is presented. It also is shown that the square-root operator can be efficiently implemented without the need to resort to multiplications or divisions, which is advantageous in terms of both area and timing.

this paper presents a low-cost frame grabber, which was specifically designed as part of a real-time motion detection system for high-resolution images. the frame grabber is FPGA-based to minimise size of the PCB and improve reliability of the system. It also acts as a backend add-on card for an IBM-PC compatible. the experimental tests carried out on different machines show that the board implemented meets all specifications required by the system, and performs well. the captured frames are clear, well contrasted and jitter-free in both live and still video modes and their quality is comparable to that available from equivalent commercial systems.

An FPGA-based reconfigurable system may contain boards of FPGAs which are reconfigured for different applications and must work correctly. this paper presents a novel approach for rapidly testing the interconnect in the FPGAs each time the system is reconfigured. A low-cost configuration-dependent test method is used to both detect and locate faults in the interconnect. the `original configuration' is modified by only changing the logic function of the CLBs to form `test configurations' that can be used to quickly test the interconnect using the `walking-1' approach. the test procedure is rapid enough to be performed on the fly whenever the system is reconfigured. All stuck-at faults and bridging faults in the interconnect are guaranteed to be detected and located with a short test length. the fault location information can be used to reconfigure the system to avoid the faulty hardware.

this paper presents a new custom computing machine (CCM) which combines a RISC core processor with rapidly reconfigurable FPGA, more closely than in any of the currently available custom computing machines, by a highly efficient flexible interface. the pyramidal architecture reconfigurable (PARC) resources are characterized by a fine-grained array of optimized logic blocks and hierarchical routing resources which can be totally configured in as short time as 25 /spl mu/sec. the new RISC core processor is dedicated to fast dynamic configuration systems; it uses a reduced instruction set, hardware and software interrupts, etc. the interface provides to the PARC-FPGA the current state of the processor and allows the RISC processor direct access to the routing resources. It also provides direct programmable access between the PARC-FPGA and the RISC processor bank registers. this interface facilitates the sharing of hardware or software functions by the RISC core processor, and the reconfigurable logic resources. the circuit was designed using Synopsys (CAD) tools, VHDL hardware description language, and the 0.8 /spl mu/m BiCMOS technology, to operate with a 40 MHz clock frequency.
