Object-oriented techniques in hardware design

We focus on using object-oriented techniques to improve the hardware design process. The advantages of these techniques for hardware design include: improved modifiability and maintainability of models; easy component instantiation with different parameters; quick composition of new components; the ability to identify and reuse common components; the ability to tailor general-purpose components to more specialized components; support of dynamic object creation and destruction; and the possibility of employing existing software synthesis and verification techniques. We illustrate the application of object-oriented techniques using a load-store, reduced instruction-set processor that contains a local memory. The instruction set consists of 22 instructions, which require one or two 16-bit words. Arithmetic is performed in two´s complement. We use C++ to demonstrate the usefulness of object-oriented techniques, not to provide arguments for or against its use in hardware modeling and design.<>
