A General Reconfigurable Architecture for the BLAST Algorithm

The process of DNA sequence matching and database search is one of the major problems of the bioinformatics community. Major scientific efforts to address this problem have provided algorithms and software tools for molecular biologists since the early 1970s. At the algorithmic and software level BLAST is by far the most popular tool. It has been developed and continues to be maintained and distributed by the NCBI organization. The BLAST algorithm and software is computationally very intensive and as a result several computer vendors use it as a benchmark. On the other hand no systematic approach for hardware speedup of BLAST and its variants for different query and database size has been reported to date. In this paper we present our architecture that implements the BLAST algorithm for all of its major versions, and for any size of database and query. The system has been fully designed and partially implemented with reconfigurable logic. It consists of software and hardware parts and achieves a speedup of several times up to thousands of times vs general purpose computers.

Analysis of Test Application Time for Test Data Compression Methods Based on Compression Codes

We present an analysis of test application time for test data compression techniques that are used for reducing test data volume and testing time in system-on-a-chip (SOC) designs. These techniques are based on data compression codes and on-chip decompression. The compression/decompression scheme decreases test data volume and the amount of data that has to be transported from the tester to the SOC. We show via analysis as well as through experiments that the proposed scheme reduces testing time and allows the use of a slower tester. Results on test application time for the ISCAS'89 circuits are obtained using an ATE testbench developed in VHDL to emulate ATE functionality.

A dynamic bandwidth control scheme of VP in ATM networks

This paper proposes an efficient adaptive bandwidth allocation scheme of virtual paths. The bandwidth of a virtual path is dynamically adjusted according to the link residual capacity. The scheme can remarkably reduce the load on node processing and simplify the network architecture, while keeping higher transmission efficiency. The excellent performance is proved by detailed theoretical analyses.
