Abstract

Typical sign language translator glove utilize general purpose microcontroller or microprocessor module which is higher in power consumption due to unused General Purpose Input Output (GPIO) and other functional blocks. Thus, a System-on-Chip (SoC) is designed using Intel 8051 Intellectual Property (IP) core as a substitution for the conventional microcontroller module to achieve higher integration while reduce the power consumption. In this work, a sign language translator glove for speech impaired community has been developed as the application. Trend of changes in sensors are used as the input of the system through the Inter-Integrate Circuit (I2C). The manipulated data will be transmitted though UART bus protocol to a Bluetooth Low Energy (BLE) module. The data is received by an Android smartphone for comparing with the database that are stored on Firebase Cloud Database and it will produces the corresponding output of the gesture through the speaker and display. Validation, simulation, verification and synthesis of the proposed design are implemented using Synopsys tools in SilTerra 180nm process technology to produce the final layout (GDSII) that is fabrication-ready. Zedboard SoC Development Board is utilized to simulate the system to validate the functionality of the work. Power optimizing techniques such as clock gating are implemented in order to further reduce the power consumption of the developed system. Effectiveness of techniques used will be evaluated from the aspect of power consumption, delay and layout size. By reducing the power consumption of the IoT devices, this could greatly prolong the battery lifespan of the application which directly increase the possibility of the application to be commercialize as there are no such device on the market currently.
