In this research paper, a Microstrip Triangular Patch Antenna(MTPA) with (80mm, 55mm, 39mm) size is designed for Land and Maritime military communication system(4990–5000)MHz and WLAN 5.8GHz(5725–5850) MHz. The antenna is coaxially probe fed with relative permittivity (εr) 4.4 and height is 1.6mm. The above said antenna generate two resonance modes between (4941–5068) MHz, bandwidth (2.54%) with center...
Minnick counter is a special kind of electronic circuit that is employed to determine the number of ones in a binary input sequence. Here we have proposed a circuit which can determine the number of ones in a binary sequence. If we look close to the circuit then we may find that this circuit can also be used as a Full Adder circuit with a little alteration. The 3 bit Minnick Counter circuit can act...
The Automata Processor was designed for string-pattern matching. In this paper, we showcase its use to execute integer and floating-point comparisons and apply the same to accelerate interval stabbing queries. An interval stabbing query determines which of the intervals in a set overlap a query point. Such queries are often used in computational geometry, pattern matching, database management systems,...
The Micron Automata Processor (AP) is a novel co-processor accelerator that supports the parallel execution of multiple Nondeterministic Finite Automata (NFA) programmed directly into hardware over a single data-stream. In this paper, we present a number of programming techniques to develop automata that execute efficiently on this processor. First, we present general techniques to transform NFAs...
The Automata Processor is a new accelerator technology that supports direct hardware implementation of a set of non-deterministic finite automata over a streaming input, and is designed for complex string pattern matching applications. In this paper, we broaden the scope of this architecture beyond its primary design goal, by developing algorithmic techniques to solve problems on unweighted graphs...
In this paper, we study the acceleration of applications that require searching for all occurrences of thousands of string-patterns in an input data-stream, using the Automata Processor (AP). For this purpose, we use two applications from two fields, namely, network security and bioinformatics. The first application, called Fast-SNAP (for Fast-SNort using AP), scans network data for 4312 signatures...
Finding approximately conserved sequences, called motifs, across multiple DNA or protein sequences is an important problem in computational biology.

Finding approximately conserved sequences, called motifs, across multiple DNA or protein sequences is an important problem in computational biology. In this paper, we consider the (l, d) motif search problem of identifying one or more motifs of length l present in at least q of the n given sequences, with each occurrence differing from the motif in at most d substitutions. The problem is known to...
