A BCD to Hex Dual 7-Segment Display Driver IC using a PLD
This is the JEDEC and Source for both a Dual 7-Segment Hexadecimal and a Single 7-Segment Hexadecimal Display Driver using GAL22V10 and GAL16V8 PLDs. The driver uses a clocked input to multiplex the displays, so that one display is lit when the clock is high, and the other when the clock is low. With a fast enough clock speed the two displays both appear to be displayed at the same time. The code is written for WinCUPL. See the Instructables page for more details. http://www.instructables.com/id/Dual-BCD-to-Hex-7-Segment-Driver/
Media Lab Asia collaborated with IIT Delhi for development real-time kernel O/S named “RTKER OS” portable on microprocessor based systems and a Multithreaded O/S for 8-bit microcontrollers (like 8051 and ATMega128) as low cost embedded solution.
