Sensing and measuring of accelerations is the basic technique in dynamics investigations. Most of the existent accelerometers are stand alone sensors providing analog voltage to the output or the system in package sensors that provides the accelerations at the most 14 bits on a serial interface. In this paper we present an original design for an embedded system which is able to compute the speed and position based on signals for 3-axis accelerations from analog sensors. The proposed solution meets the requirements of a high resolution, in particularly on 16 bits, using an 8 bit RISC processor. The particularity of our solution consists in locally computing on the same processor unit of the six additional kinematic parameters which usually are performed in a distinct post processing stage on a separate computing unit. This paper also presents a study on the response time evaluation based on the time consume for specific tasks on the proposed architecture.
