Abstract
Object-Oriented Programming (OOP) has good features in Encapsulation, Inheritance, polymorphism and dynamic Blinding, and provides better characteristics in security, maintainability and reliability. However, when executed in a traditional von Neumann machine, object-oriented programs are much slower than their procedural-oriented counterparts. The main reason is due to that attributes and data cannot be directly accessed in OOP. Actual physical addresses of attributes of objects/classes should be calculated through a complex address transformation. In the paper, we proposed a new computer architecture supporting OOP in hardware. An object attributes access mechanism using an operand descriptor structure greatly increases performance of attribute fetching, and speeds up OO programs by an order of magnitude.
