Therefore, they are at least twice as fast as the known architectures. Also, their AT/sup 2/ parameter is approximately 1/2 of that of already existing devices. These results allow either a twice faster processing than that allowed by other architectures working at the same clock frequency (High-Speed utilization), or using a twice lower clock frequency, while reaching the same performance as other architectures. This second possibility permits reducing the power dissipation by a factor of 4 with respect to other architectures (Low-Power utilization). Finally, we shall show that an impressively efficient architecture can be defined as the synthesis of Arc/sub J/ and Arc*/sub 2/ (average efficiency=99.1%, minimum efficiency=93.8%).","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

Based on the radix-2' Booth algorithm, the modified transposed direct-form FIR architectures with and without programmable dynamic ranges of input data and filter coefficients are formulated. The complexities, throughput rates and complexities per throughput rate of the FIR architecture with and without various programmable dynamic data ranges are analyzed in different radix numbers of the Booth algorithm. According to our analyses: the radix-4 approach would be a good choice to achieve a low hardware complexity. For a high throughput rate, the radix 16 or higher radix number of the Booth algorithm should be considered. But if complexity per throughput rate is important, then the radix-8 and radix-16 approaches may be preferred in the FIR architecture without and with programmable dynamic data ranges: respectively. Therefore, users can apply our results to determine a suitable radix number of the Booth algorithm for designing the optimized FIR architecture with consideration of the chip area, speed, throughput rate, power consumption and so on.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

A watermark signal is embedded in a grayscale or a color host image. The watermark key controls a set of parameters of a chaotic system used for the watermark generation. The use of chaotic mixing increases the security of the proposed method and provides the additional feature of imperceptible encryption of the image owner logo in the host image. The method succeeds in detecting any alteration made in a watermarked image. The proposed method is robust in high quality lossy image compression. It provides the user not only with a measure for the authenticity of the test image but also with an image map that highlights the unaltered image regions when selective tampering has been made.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

To no one's surprise, the analysis suggests that SC outperforms SI considerably for the past and present technologies. However, as processing heads towards lower power supply voltages the performance of SC falls steadily while that of SI remains almost constant. Ultimately, there is a fundamental tendency for the performance gap between SC and SI to steadily reduce and SI performance is expected to match and surpass that of SC during the course of the next decade.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.

This approach can supply a high level of accuracy. A complex structure is reduced first to series-connected MOS, then the delay equations are applied to that reduced rate. The model is based on a time piecewise linearization so that a strongly nonlinear circuit can he solved using well known linear techniques. The delay formulas involve model parameters as MOS width functions, therefore providing routines suitable for optimization algorithms. The high level of accuracy, the low CPU time and the high degree of scaling capability are proved in the paper. These features make the model attractive for deep submicron technologies.","PeriodicalId":6422,"journal":{"name":"2000 IEEE International Symposium on Circuits and Systems.
