Performance Evaluation and Analysis of ParallelSoftware Implementations of TDES on a16-PEEmbedded Multiprocessor Platform

Embedded system design is increasingly based on single chip multiprocessors because of the high performance and flexibility requirements. Contrary to desktop multi-core and usual multiprocessors, embedded multiprocessors are tightly constrained for the number of external DDR memories due to pin constraints which in turn may affect concurrency access for embedded parallel software implementation. In this paper we explore the implementation of block cipher TDES (Triple Data Encryption Standard) cryptographic algorithm on a 16 processor single chip multiprocessor using two parallelization techniques; the first one by data parallelism where each processor executes the entire TDES algorithm, the second is a pipelined TDES distributed on these 16 processors.
