PROJECTS
1. ELAN SC310 based Graphic terminal firmware porting
Organization : HCL Peripherals, Chennai
Platform & Software : Dos, C, 80X86 assembly
Hardware : ELANSC310 based motherboard
Team Size : 3
Client : In house project
Duration : 4 months
Description :
The Graphic terminal is a Unix dumb terminal and is capable of displaying signatures and photographs. This is widely used in the banking sectors. The main objective of this project is to take care of the obsolescence of 80386 processors in the market. The 80386 processors are replaced by AMD ELAN SC310 microcontrollers which has the integrated PC/AT logic.
My role
1. To modify the existing firmware to run on ELAN SC310 based new graphic terminal.
2. Serial EEPROM driver implementation to save the terminal parameters.
3. Overall management of prototype logic card assembly and testing and product release
2. GIST Multilingual terminal development
Organization : HCL Peripherals, Chennai
Platform & Software : DOS, 68000 Assembly
Hardware : Motorola 68000 based logic board with two serial ports, one printer
Port, monitor and keyboard.
Development tool : ORCAD, ALTERA MAXPLUS II FPGA Tool
Team Size : 2
Client : In house project
Duration : 7 months
Description :
The GIST multilingual terminal was originally developed by CDAC, Pune, We are one of the licensee to develop and manufacture GIST terminals. This GIST terminal is a Unix dumb terminal and capable of displaying almost all the Indian Scripts and some of the Foreign Scripts. The objective of this project is to replace 68000 CPU with 68EC000 CPU and to implement almost all of the discrete ICs in an ALTERA FPGA FLEX10K10.
My role
1. The schematic design of the circuit diagram using ORCAD
2. Schematic design of FPGA components using MAXPLUS II graphics editor and compilation.
3. Developing diagnostic software to test the on board components
4. Firmware modification to suit the new design
5. Hardware debugging and hardware design changes
6. Overall management of prototype logic card assembly and testing and product release
3. GIST terminal enhancement
Organization : HCL Peripherals, Chennai
Platform & Software : DOS, 68000 Assembly
Hardware : Motorola 68000 based logic board with two serial ports, one printer
Port, monitor and keyboard.
Team Size : 1
Client : In house project
Duration : 3 months
Description :
The following new hardware and software features were designed and developed by me to the GIST Terminal to meet the customers requirement
a. Serial EEPROM Implementation
The main objective of serial EEPROM implementation is to replace battery backed SRAM circuit with cost-effective 2Kbytes serial EEPROM. This EEPROM is used to save the terminal parameters such as data size, baud rate, parity, emulation and terminal operating modes etc. The battery backed SRAM was removed and a new circuit was designed based on serial EEPROM.
b. 115K baud rate implementation
The existing GIST terminal supports maximum of 38.6K baud over the RS232 communication port. This feature is added to extend the terminal capability to communicate up to 115.2K baud
c. Function Key Programming
Function keys F1-F12, Editing keys and cursor keys were made programmable to the user with shift, control and Alt combinations. This will allow the user to define the function keys the user wants.
d. Password protected setup.
The password protection was implemented to prevent unauthorized persons to changing the terminal parameters.
e. AT keyboard support.
The AT keyboard interface was designed based on the keyboard controller 8042 to replace the existing XT keyboard and AT keyboard driver coding.
f. High display refresh rate.
The display refresh rate was increased from 50Hz to 66Hz to give a flicker free display.
4. Dos based Windows Terminal
Organization : HCL Peripherals, Chennai
Platform & Software : Dos, NT-TSE, CITRIX Dos based ICA clinet and CITRIX Metaframe
Hardware : Standard MediaGX based motherboard.
Team Size : 2
Client : In house project
Duration : 2 months
Description :
The Citrix Systems, USA has developed an innovative server based computing technology called Indepentent computing Architecture (ICA). This is widly know as Windows based Terminal or Thin Clients. It has two parts a server and a client. The server called Metaframe should be installed on Windows NT-TSE server (Recently Citrix released Metaframe for Solaris) and the client called ICA client which Citrix developed for almost all the available Operating systems. This ICA client is capable of connecting to Windows NT-TSE server and brings the Windows NT-TSE desktop. Now any application that are possible in the Windows NT-TSE console can be run from the remote terminal. We are one of the OEM customers for Citrix Systems in India. We developed this product based on Dos operating system and found the performance was not satisfactory. So we dropped this product and developed same kind of product based on Linux operating system.
5. Linux based Windows Terminal
Organization : HCL Peripherals, Chennai
Platform & Software : Linux, C, X-Motif and Unix shell programmming, Windows NT-TSE,
CITRIX Linux based ICA client and CITRIX Metaframe server
Hardware : Standard MediaGX based motherboard.
Team Size : 4
Client : In house project
Duration : Current development since July99
Description :
I am currently working on the Linux based Windows Terminal. We selected Linux based ICA client, since it is faster and also it is a free software. We developed this product based on Redhat Linux 4.2 (Kernel version 2.0.35). We customised Redhat Linux 4.2 to fit into an 8Mb Disk On Chip. This product has the customised Linux operating system and Xfree86 X server. Since the ICA client is a standard X application, it is ran over the X server. Apart from the ICA client, We integrated telnet for Unix character based applications and XDMCP for Unix GUI based X aplications. We developed a GUI application based on X-Motif for local administration like Network setting, host setting, local users setting, XDMCP setting, PPP settings etc.
My Role
1. Redhat Linux customisation and Linux custom kernel compilation.
2. X Server and FVWM window manager configuration
3. GUI development using X-Motif and C for easy user configurations.
4. Shell scripting for back end processing.
5. PPP, XDMCP support addition.
6. Customer training and product demonstration.
7. Windows NT-TSE server configuration and CITRIX Metaframe server configuration.
8. Touch screen integration
6. Bug fixing Terminals
I have fixed various bugs then and there reported from the field on Graphics terminal and GIST terminal.
