As a part of the Embedded Software team I have worked on the software development of next generation wireless PAN (personal area networking) device. We have developed customized protocols on the top of TCP layer and MAC layer. Project also involves the understanding and usage of LWIP [light weight TCP/IP stack], WiMedia, Green Hill’s micro-velocity RTOS, PCAP library and Win32 APIs.

As a part of the Embedded software development team we have designed and developed the IPTV set-top box software stack. In the project startup I had to develop the prototype of system within 3-4 months. After successful demonstration I was involved in the hiring and team building process as well. Then after building a team of 5-6 developers my responsibilities were to train them to start development on the existing system which included the understanding of tool-chain, development environment and file-system etc. After that my responsibilities were to guide them in their technical problems as well.Major components in which I was the main contributor are: ★ Network Streaming Protocols Reverse-Engineering and Implementation; including MMS(Microsoft Media Server), MMSH, HTTP and RTSP.★ ASF(Advanced Systems Format) Demuxer Reverse-Engineering and Implementation.★ Design and development of Qtopia based Multi-threaded Media Player.★ Porting Qt core/embedded to our device to be used as UI library and Framework for Application development.★ Porting Gstreamer and its Plugins to our device to be used as Multi media framework, for live streams playback.★ Design and development of Gstreamer based Source Plugins to get the streams from Microsoft Media Servers.★ Design and development of Qtopia based Network Configuration Wizard and System Startup Wizard.★ Debugging of multithreaded and memory issues, like memory leaks, memory corruption and deadlocks etc.★ Debugging of media framework level issues, like audio and video synchronization.★ Tweaking U-boot and Linux kernel 2.6 to make system ready for public release.★ Debugging of WMA Decoder’s kernel module.

Worked part time to redesign and developed a win32 based Application called AFE {Automatic Fraud Elimination} Client. The main responsibility of that client is to receive the Call Records from multiple E1 lines on real-time basis and then parse and save the required fields in the database/files. To achieve the real-time response I and one of my colleagues have designed and developed a multiple queues based pipelined and multithreaded Client Application which is deployed at Gateway Exchange of PTCL located at Sixth Road Rawalpindi.

Research on the Software level Power Optimization of Reconfigurable Systems with Dr. Shahid Masood. Mainly worked on the Leon3 processor and its Instruction set which is a 32-bit soft-processor based on SPARC V8 architecture. It implements a 7-stage pipeline and separate instruction and data caches. Initially I have synthesized the leon3 based system on SPARTAN-III FPGA board using Xilinx ISE. And then I have used ModelSim to profile the Instruction set, on the basis of power consumption.

As a part of this startup I was involved in the Design and Develop of a SIP Video VOIP phone software stack from scratch on freescale i.mx21 application processor. i.mx21 contains arm9 integer processor core with latest configurable peripheral controllers and built in video acceleration core. I have used Board Support Package which includes Linux kernel 2.4 and supporting drivers. I have managed to develop a functional demo. To accomplish that I have worked on followings:★ Platform Creation Suite.★ Debugging of im8012 device driver.★ Use of V4L2 for the image capturing.★ Developing of video post processor device driver.★ Porting libraries of open source protocol stacks like OSIP and ORTP.★ Use of hantro codec libraries for mpeg4 and h263 encoding/decoding.★ Understanding of Linux kernel and file system.★ Use of multi threading for close to real-time response. ★ use of dma driver and video overlay driver.★ good understanding of make file and static and dynamic libraries.★ use of OSS library for audio input and output.★ porting audio codecs like G711 (PCMA/PCMU), Speex and GSM-AMR.★ And finally the application which integrate all these components to give the functionality of SIP VIDEO VOIP Phone.
