Experience
  • Language Design
    • Designed and implemented Unicorn. The basic idea was to add new control constructs to C that would allow backtracking based Prolog like goal searching control flow within and across C functions, and provide C++ like classes and overloaded operators to enable the programmer to define unification as just a class library.
    • Designed and implemented a processor description language for automatic generation of cycle accurate simulator, assembler and disassembler for a processor from a succinct definition of its instruction set architecture, execution model and memory model.
  • High-Level Code Generators
    • The implementation of Unicorn generates equivalent C code for an input program.
    • The implementation of the processor description language generates C++ code files for the simulator, assembler and disassembler of the processor.
    • Wrote a translator to convert a high level Magic-C system description to equivalent SystemC code.
    • Wrote a translator to convert a high level Magic-C system description to equivalent C++ code for a time-traveling simulator for the system, that allowed going back in simulation as well as forward.
  • Compilers
    • Wrote a compiler for a reasonably large subset of C, using lex and yacc.
    • Wrote a compiler in ML for a Pascal like language featuring garbage collection, using ml-lex and ml-yacc.
  • Interpreters
    • Wrote an interpreter for the Lambda Calculus.
    • Wrote a semantic interpreter, in Haskell, for a simple hybrid imperative/functional programming language.
  • Simulators
    • Wrote an event based simulator for digital circuits. Implemented a graphical user interface for editing and simulating digital circuits.
    • Wrote a cycle based simulator for REX networks. Implemented and tested a one instruction set computer (a mov-machine) using REX network components.
    • Wrote a cycle accurate simulator for National Semiconductor's CR16c processor.
Languages &
Skills		 Programming in C, C++, ML, Haskell, Prolog, Java, Scheme, MIPS/x86 Assembly.
