Based on the gray system theory, the GBMA can determine the better motion vectors of image blocks quickly. The experimental results show that the proposed algorithm performs better than other search algorithms, such as TSS, CS, PHODS, FSS, and SES, in terms of four different measures: 1) average MSE per pixel, 2) average PSNR, 3) average prediction errors per pixel, and 4) average search points per frame. The VLSI architecture of the algorithm has been designed and implemented, and it can yield a search rate of 680 K blocks/sec with a clock rate of 66 MHz.","PeriodicalId":275030,"journal":{"name":"1999 IEEE Workshop on Signal Processing Systems.

We propose two simple basic cell architectures which evaluate the error locator and the error magnitude polynomial in the general Euclid's algorithm. The evaluation involves high computational complexity, and thus, it affects the speed and the hardware complexity of RS decoders. The proposed architectures can reduce the hardware complexity by more than 16% of existing RS decoder architectures. The proposed RS decoder can be programmed to decode four RS codes defined in Galois field 2/sup 8/, i.e., (200, 188), (120, 108), (60, 48), and (40, 28) and can correct up to six errors. The fabricated FEC (Forward Error Correction) chip including the RS and Viterbi decoders operates at 40 MHz. The total number of gates for the RS decoder is about 31,000 and the FEC chip contains about 76,000 gates.","PeriodicalId":275030,"journal":{"name":"1999 IEEE Workshop on Signal Processing Systems.

In this paper an optimal pipelined architecture for a 2nd order allpass section based on 3-port adaptor is proposed. Optimal pipelining improves the filter's overall performance in term of power-delay-area by 4.8 times using 1 /spl mu/m CMOS standard cell design and by 10 times using custom cells. Given the same clock speed and without the use of supply voltage scaling, the architecture consumes 58% less power than the non-pipelined equivalent using custom cell implementation and by 50% using standard cells. With a maximum throughput of 277 MHz, the adaptor's power consumption is 5.44 mW/MHz, representing a 64% improvement in power efficiency relative to the non-pipelined standard cell adaptor.","PeriodicalId":275030,"journal":{"name":"1999 IEEE Workshop on Signal Processing Systems.

This methodology is based on a generic, scaleable architecture for the wavelet filters. The architecture offers efficient hardware utilization by combining the linear phase property of biorthogonal filters with decimation in a MAC based implementation. The design has been captured in VHDL and parameterised in terms of wavelet type, data word length and coefficient word length. The control circuit is embedded within the cores and allows them to be cascaded without any interface glue logic for any desired level of decomposition. The design time to produce silicon layout of a biorthogonal wavelet based system is typically less than a day. The resulting silicon cores produced are comparable in area and performance to hand-crafted designs. The designs are portable across a range of foundries and are also applicable to FPGA and PLD implementations.","PeriodicalId":275030,"journal":{"name":"1999 IEEE Workshop on Signal Processing Systems.

In earlier work, we have formalized a methodology to achieve this. This methodology is based on the application of a number of power optimizing code transformations to a system-level description of the target application. Our script has recently been extended explicitly to take into consideration the required performance (in number of execution cycles), which is the overriding constraint in real-time multimedia applications. In this paper, we focus on a systematic use methodology that allows to apply this script in practice in a manual way on a complex application, including the necessary local design iterations. Experimental results from a real-life data-dominated application demonstrate that the application of the proposed systematic approach leads to significant power and performance gains compared to reference designs.","PeriodicalId":275030,"journal":{"name":"1999 IEEE Workshop on Signal Processing Systems.
