   	       PROFESSIONAL EMPLOYMENT / EXPERIENCE

     Experience in VLSI CAD Simulation, Placement
     and Routing, Verification, Testing, Analysis, 
     Schematic Capture, Cell Generation, Logic Synthesis
     I was part of the VHDL Synthesis group. 
     Developed a verilog netlist model of the central 
     processing unit of a RISC machine on Sun Sparcs II.
     The implementation contained behavioural description
     along with timing checks, error handling etc.
     Used Magic( VLSI layout tool), Spice, Esim, VALID 
     simulators for VLSI design, Verilog (HDL Software)

   * COMPUTER MAINTENANCE COMPANY	    May - Aug 90

     Learnt Practical Aspects about high speed adaptive
     equalization modems, muliplexers, LAN hardware and 
     peripherals, Interfaces, Circuits for Analog Sampling
     and Filtering, Token Ring Protocol Networks
     point-to-point, multipoint, leased or dialup 
     communication links, VAX 6600 Architecture, Disk Drives
     Wrote an inventory control system for spare parts
     Error Detection, Fault Tolerant Hardware.

    
   * Compiler for SNOOP: an Object Oriented Language

     Designed the SNOOP Object Oriented Language.
     I used lex and yacc to scan and parse and construct 
     a DAG. I wrote a semantic error checker, a run time 
     debugger, and facilities for overloading, encapsulation,
     multimethods, method combination, inheritance, 
     metaclass protocols and a run time polymorphic method
     determination for class objects, garbage collection, 
     dynamic memory allocation. The compiler was over 
     10,000 lines of C code.


   * File transfer protocol and gateway to gateway protocol

     Implemented a File Transfer Protocol based on the 
     TCP/ IP Protocol Suite and also the Gateway to 
     Gateway Protocol between the Ethernet and the 
     ISO LAN. The software was in C for a SUN SPARC I.
     Developed performance evaluation models of LANs and
     LAN based systems: Simulation models for Ethernet, 
     token-ring, FDDI, NFS, and a SCSI-2-based disk
     subsystem using SES/workbench. Administerd a network of
     Sun Sparc and Sun 3/50 workstations.

     
   * Modifications to TCP/IP for Real-Time Communication

     Designed and Implemented a new transport protocol
     to  be implemented at the same level as TCP/IP
     but with specified performance guarantees, continuous
     multimedia applications, low delay guarantee, high
     reliability.

   * Cache Simulator for MIPS R2000/ R3000 (RISC)

     I used the stack model for simulation to study data 
     prefetching, branch prediction buffers, register 
     window management schemes, superscalar machine design.
     Also studied various tradeoffs between block size,
     replacement policies, virtual and physical caches, 
     Translation Lookaside Buffers. 

   * Design, Implementation and Use of a single board 80386
     based MIMD Multiprocessor System embedded in PC-XT bus.

     This was a major design project at IIT Kanpur. 
     I was a part of the four member team which built
     the parallel processing unit using a new state 
     machine design for the interconnect.
     The board had 4 Intel-80386 CPU's each with 512Kbytes
     SRAM cache and 16 Mbytes of shared DRAM memory.
     I designed a serial communications adaptor and 
     used a FSM based logic design and a microcontroller
     for the interface. I also wrote the software for the 
     (mini) OS in assembly language. 
     The parallel procesing unit was used 
     to speed up Kalman, IIR/FIR filtering, FFT Calculation,
     logic programming, neural networks, and dictionary 
     operations. I wrote the basic operating system which
     was over 5000 lines of assembly language code.

   * Expert Production System for a Decision Support System.
   
     I wrote the shell for the rule based expert system. 
     The expert system had the capability to self learn
     and also to explain its reasoning. It used both backward
     and forward chaining. Developed in Unix/C, it had a 
     friendly X11 interface. 
	
   * Metrics based CASE Tool for Software Risk Management 

     This project was sponsored by AIRMICS, and DoD.
     I was a member of the two person team.
     The project uses Metrics, Expert Systems, GUIs, 
     Incremental Development, Concurrent Engineering, 
     Re-engineering, Computer Aided Software Engineering.
     Used influence diagrams and truth maintenance systems 
     to build a decision analytic system for risk assessment
     and control. The Influence Diagram based Expert System
     interacts with an Object Oriented Metrics Database.  
     The TMS maintains consistency in the context of 
     nonmonotonic reasoning. A rule based system envelops
     the influence diagram based expert system to enable 
     learning, explanation, flexibility and modularity.
     I have implemented over 15000 lines of C code. The
     rule based system is based on CLIPS, a forward chaining
     expert systems shell developed at NASA.

   * Client NVRAM in the Sprite Distributed Operating System

     I designed and simulated a modified client model using 
     non volatile memory to absorb write traffic to servers.
     The project also involved Unix Interprocess Communication
     mechansisms including sockets, multimedia, extensive
     shell programming, embedded makefile generation and 
     distributed compilation, fault tolerant computing, and
     revision control.

   * Software Integration: An Artificial Intelligence Approach
     
     I developed a general model of integration that leads to 
     a quantitative algorithm for choosing the best partitioning
     and test scheduling strategy. I also used Truth Maintenance
     Systems for maintaining consistency between the 
     Requirements, Specifications, Design, Coding, Testing, and
     Maintenance Phases of software development. 
     The prototype was about  2000 lines of lisp code. 

   * Multitasking O/S on PC-AT
     
     Developed a multitasking OS on an IBM AT, 80386 processor
     in Turbo C, providing a Unix like command handling shell 
     and device driving control routines for terminal I/O and
     printer. Different O/S Concepts, such as Round Robin Scheduler
     Spooler, Loader, Paged Segmentation memory manager etc. 
     were implemented. 

   * Compare and Swap for Multiprocessor Synchronization

     Implementing the Compare and Swap creates a number of new
     problems. I enhanced the Omega network with a new protocol
     to reduce hot spots and tree interference which arise 
     during the implementation of the compare and swap in 
     packet switching systems.
