Field Programmable Gate Arrays (FPGAs) are devices used in many VLSI applications, which are programmable in nature. Researchers had proposed various threat models like bit stream copying, unauthorized usage of FPGA systems etc. The problem of bit-stream copying can be avoided by incorporating cryptographic techniques. This not only increases FPGA system security, but increases complexity and c...

For sys tem or board d iagnost ics , AT6000 Series devices can be programmed with the 1149.1 standard test logic and then reprogrammed for normal operation when the diagnostics are comple te . The area and per fo rmance overhead of the test logic does not impact normal operation in the device because it is replaced by the logic for normal function. All mandatory test instructions can be execute...

The VAXstation 4000 Model 90 is the latest member of the VAXstation product line. Based on the NVAX CPU, the Model 90 was designed as a module upgrade to the VAXstation 4000 Model 60 system. The Model 90 has 2.7 times the CPU performance of the Model 60 and provides base-level, two-dimensional graphics performance of 266,000 vectors per second. It supports up to 128MB of memory, an SCSI-1 bus i...

Problems facing in design migration from FPGA to standard cells design approach are discussed. Standard cell implementation of a parallel multiplier with bit-sequential input and output, using FPGA design as a prototype is considered. It is shown that careful redesign is required, because of incompatibility of the cell libraries. Also the FPGA design complexities don't present any relation to d...

We propose hybrid CMOS/nanodevice circuits which have potentials to perform massively parallel high throughput computations and in particular suitable for pattern matching. The performance advantage of novel circuits is mainly due to very high density of nanoscale devices and very tight and synergetic integration of memory and logic functionalities. The tight integration is enabled by high comm...

Parallel approaches to Inductive Logic Programming (ILP) are adopted to address the computational complexity in the learning process. Existing parallel ILP implementations build on conventional general-purpose processors. This paper describes a different approach, by exploiting user-customisable parallelism available in advanced reconfigurable devices such as Field-Programmable Gate Arrays (FPG...

Hardware Description Languages (HDL) like VHDL are widely used to design and simulate with programmable logic devices. Simulation of very large scale integrated digital systems (VLSI) is of great importance as it assures system correctness and maximizes system performance ([4], [5], [9]). The utilization of parallel simulation introduces the problem of how to partition the logic gates and syste...

In a laboratory environment, the practicality and scope of experiments is often constrained by time and financial resources. In the digital hardware design arena, the development of programmable logic devices, such as field--programmable gate arrays (FPGAs), has greatly enhanced the student’s ability to design and synthesize complete systems within a short period of time and at a reasonable cos...

A real-time encoding and decoding system (REDS) for HDTV that can be used for nonlinear HDTV editing in studio has been developed. The intrapicture coding of motion JPEG is implemented and optimized in the REDS so that a high-quality image can be recovered for the nonlinear editing. The REDS has a parallel architecture with multiple programmable digital signal processors (DSP) and reconfigurabl...
