Pattern matching, the problem of finding sub sequences within a long sequence is essential for many applications such as information retrieval, disease analysis, structural and functional analysis, logic programming, theorem-proving, term rewriting and DNA-computing. In computational biology the essential components for DNA applications is the exact string matching algorithms. Many databases like GenBank were built by researchers for DNA and protein sequences; the string matching problem is the core problem for searching these databases. As the size of the database grows, the more important research area is to design an efficient string matching algorithms. This paper proposes a new pattern matching technique called An Index based Pattern matching using Multithreading for DNA sequences. The method specified in this paper performs parallel string searching using multiple threads simultaneously, each thread is responsible for searching one part of the text.. The proposed algorithm is an efficient algorithm that can be used to search for exact occurrences of patterns in DNA sequences.

Abstract-Elastic systems operate in a dataflow-like mode using a distributed scalable control and tolerating variablelatency computations. At the same time, multithreading increases the utilization of processing units and hides the latency of each operation by time-multiplexing operations of different threads in the datapath. This paper proposes a model to unify multithreading and elasticity. A new multithreaded elastic control protocol is introduced supported by low-cost elastic buffers that minimize the storage requirements without sacrificing performance. To enable the synthesis of multithreaded elastic architectures, new hardware primitives are proposed and utilized in two circuit examples to prove the applicability of the proposed approach.

“…When a hazard happens, the pipeline has to be stalled until the dependency is resolved, which degrade the performance. Multi-threading processor design [1] improves the execution efficiency of the processor pipeline by exploiting thread level parallelism, and has been applied to high-end network processor systems.…”

Abstract-Multi-threading pipelined processor design enables high performance of a single processor core by exploiting both thread-level and instruction-level parallelism. However, when it is applied to embedded systems, its demanding for large register file, hence high resource overhead and energy consumption, becomes a big issue. In this paper, we propose a customization approach to reduce register file by maximally utilizing each of the registers used. The experiments on several applications demonstrate that with our approach, the register file for a single thread can be reduced by about 50%, based on which the multi-threading processor can achieve high performance while at low energy consumption -with 17-28% throughput improvement and 20% energy reduction when compared to the single-threading processor design.Index Terms-Register file customization, multithread pipeline, energy-aware design.
