Project Details
1. Project name Cross compiler for 16-bit fixed point DSP architecture
Date November 2003 to November 2006
Client OKI Electric, Japan
Company Acme Technologies Pvt. Ltd.
Description:
This project is aimed to develop the backend for 16 bit fixed point DSP processor by using front
end of existing ANSI C cross compiler for the b-bit RISC processor. Backend of the compiler
was developed from scratch. Front end was modified as per technical report on Embedded
C (TR 18037) according to the additional requirement of DSP-C specification.
Technical Specification
Languages used C (ANSI C), C++, Assembly language (DSP and RISC architectures),
HTML and XML
Development Environment Microsoft VC++ IDE, Microsoft Visual Studio .Net IDE
Platform Windows 2000/XP, Linux Kernel
Scripting Languages Perl and Python
Roles and responsibilities
• Study and research
o Study and understand the usage of compiler tools like flex, bison, lex, yacc.
o Study and understand 16 bit fixed point DSP architecture.
o To perform architecture dependent optimizations like Zero Overhead Loop
optimization, peephole optimization, ILP and Scheduling (instruction level parallelism),
Conditional Instruction and MAC (Multiplication and ACcumulation) Instruction.
To perform SSA based optimizations like: Dead Code elimination, Code Motion
o
(Loop variant code motion, loop invariant code motion), Code Hoisting, Code Sinking,
Loop optimizations (loop transformation, loop unrolling).
To perform a local register allocation.
o
o Restrictions of the architecture.
Study and analysis of architecture included hand-coding of DSP applications like:
o
FFT in assembly language. The aim of hand-coding was to achieve the best possible
memory organization, maximum ILP and the best possible utilization of instruction set
supported by the architecture.
To understand the local, global and loop optimizations done in the front-end.
o
• Design and Development
Responsibility to design, develop and test Zero Overhead Loop Module. This
o
module takes C level code as input and generates intermediate code as output.
Requirement is to convert a source level loop into Zero Overhead Loop instructions
supported by the architecture.
Responsible for designing, developing and testing the local register allocation
o
module.
Involved in QA C (Quality Assurance) and True Coverage testing.
o
Analysis and Design of Delay Slot Optimization and PC relative addressing.
o
Formulated design rules for ILP.
o
• Review and discussion
o Review the design and code written by other members of the team. Each design
decision in a module is discussed and cross-examined by the whole team. This builds
a comprehensive knowledge on other modules as well like register allocation,
instruction level parallelism and memory organization
• Testing
Performed Perennial testing to verify the output generated by compiler.
o
-2-
Writing test cases to verify compiler is in compliance with specification.
o
Done Unit testing of Zero Overhead Loop module.
o
Used test case generator for testing the compiler.
o
Done testing using batch processing.
o
• Defect fixing
Involved in fixing of defects found in various modules of compiler.
2. Project name Cisco IOS Compilers and Tools
Date November 2006 to September 2008
Client Cisco Systems Inc., San Jose, CA
Company HCL (HCL-Cisco, Cisco Offshore Development Centre)
Description
The aim of this project is to customize and build a newer version of GNU C compiler (gcc) and
migrate the Cisco IOS release trains to this newer version of gcc. It has two stages:
• Readiness of the compiler: It involves upgrading the GNU C Compiler to a new version
by adding new features to make it more ANSI compliant as well as by adding patches to
fix the bugs in the previous version of the compiler.
• Readiness to migrate a branch: Cisco IOS is migrated to the new version of gcc once
the compiler is ready to be released. This involves building, booting and benchmarking
the images.
Technical specifications
Languages used C, C++, Assembly language (MIPS and PPC architectures)
Platform Unix, Linux kernel, Solaris 8, Solaris 10
Scripting Languages Unix Shell Scripting, Perl and Python
Development tools GNU toolchain, Clearcase
Roles and Responsibilities
• Part of the sustaining engineering group for Cisco IOS compilers and tools
• Review and analysis of
IOS architecure
o
Unix and clearcase commands
o
Patches applied to the compiler
o
o Build and boot images
• Study and analysis of MIPS 32/64, Power PC, X86 assembly languages
• Customize GCC by adding patches and changing it as per the functional specification
• Study and analysis of GCC features like register allocation, SSA, RTL, AST, intermediate
code representations, GIMPLE, GENERIC
• Migrate Cisco IOS release trains
o Analyze and fix all the build issues for IOS, ION and IOU images faced while
migrating a branch to a new version of the compiler
o Analyze, troubleshoot and fix the boot issues seen due to migration of a branch to
the new compiler version
• Testing
Performed testing for gcc.c3.4.5-p1. It involved the following:
o
Study of Cisco format test suite and ION API Signature test suite
o
Write test cases for the patches gone into the compiler
o
o Verify the compiler behavior with the test suites and the test cases written for the
patches
Done testing using batch processing
o
Performed benchmarking for the compilers
o
o Product Defect fixing by analyzing and solving the run-time issues
• Reviews and Discussions of fixes and queries posted by onsite and offshore teams.
• Provide support to the Engineering community for queries related to compilers and GNU tool
chains
