  • Cellular and Smart phone through the business and real life is associated with an increasing number of information processing, Breaches associated with mobile terminal Tile has occurred and cause Crime and damage. In this paper, Cellular and Smart phone for mobile forensics SYN scheme and JTAG scheme to target Cellular and Smart phone for the extraction of forensic data will be studied. SYN, JTAG approach to forensic analysis indicate with the process, Every Smart phone's OS specific performance and data extraction were compared. In the laboratory, Cell and smart phone with the SYN scheme and JTAG scheme to extract forensic data Improvement compared to the extraction is presented.

  • A design of a preceding instruction decoding module(PIDM) is proposed aiming at performance enhancement of JTAG-based test complying to the IEEE 1149.1 standard. The PIDM minimizes the number of clocks by performing test access port(TAP) instruction decoding process prior to the execution of TAP-controlled test activities. The scheme allows the generation of signals such as test mode select(TMS) inside of a target system. The design employing PIDM demonstrates 15% performance enhancement with simulation of a CORDIC processor and 48% reduction of the TAP-controller's circuit size with respect to the conventional design of a non-PIDM version.
