Abstract: This paper presents the development of an embedded based distributed system to measure sodium, potassium and chloride ions in blood sample. The developed system consists of P89C668 microcontroller based three sensor nodes and one coordinate node. In order to handle more blood samples and reduce the analyzing time, the temporal based concurrent operation is implemented on the sensor nodes. The proposed system architecture and the co-design of hardware and software are discussed in detail. The performance of the system is evaluated using speedup, efficiency and throughput. The result shows that system attained the sub-linear speedup in measurement of blood samples.

Keywords: Distributed Embedded System, Decentralization, Temporal Parallelism, Clinical Blood Analyzer.
