K-mer (k length substrings in a DNA sequence) counting plays an important role in genome assembly, sequence analysis, and error correction in sequence reads. In the Gene data sets, a single occurrence of k-mers occupies more storing space with a higher possibility of sequencing errors. Hence, error correction plays a significant role in eradicating such uninformative k-mers. Bloom filters data structure has been frequently used in k-mer counting for determining thek-mer occurence at least twice in a data set of a DNA sequence owing to its less memory usage and its fast querying. The standard bloom filer used in k-mer counting is not cache efficient as it accesses the whole bloom filter memory for single k-mer insertion/query. Also the Murmur hash consumes more time for hashing the k-mers from the Input Sequence. In this proposed work, we have improved the process of k-mer counting further by adopting different bloom architecture called a partitioned bloom data structure. The proposed architecture is cache efficient and uses only one memory access instead of in the standard bloom filte’s k memory accesses. The rolling hash in ntHash function is used for hashing the k-mers from the input sequence has further reduced the hash computation time of k-mers. The proposed architecture was compared with standard architecture and the results showed that the proposed k-mer counter minimized significantly the k-mers loading and querying time from the memory for different data sets.
