Object-Oriented Hardware Design and Synthesis

Object-Oriented Hardware Design
New Synthesis Techniquesfor Object-Oriented
Specifications
SystemC

• Object-oriented SystemC hardware specification
  including
• classes
• class templates
• inheritance
• polymorphism
• object-oriented inter-process communication
• ...

• Additional C-Library,adds support for
• polymorphicobjects
• shared object, incl. scheduler

OOHWLIB
class Complex SC_MODULE( Module ) ...
void process() Complex coordinate( 0, 0
) while( true ) coordinate.setRe( 7
) ... ...

• Translation into functional equivalent
  representations
• eliminate inheritance
• replace objects
• replace member functions
• resolve dynamic dispatching
• eliminate dead members
• eliminate unused member functions
• replace shared objects

Synthesis
cycle accurate simulationof higher level
constructs

• Synthesisable lowlevel code
• Behavioral/RT SystemC orVHDL
• Processable by common tools (e.g. Design
  Compiler, CoCentric SystemC Compiler)
• in preparation
