Interface hardware design using internal and external interfaces

摘要

A computer system includes a plurality of discrete computer components and an integrated circuit that interfaces between the discrete computer components. The integrated circuit has internal hardware interfaces corresponding to respective discrete computer components. The internal hardware interfaces are selected from a limited number of available pre- defined internal hardware interfaces for general kinds of computer components. The internal hardware interfaces are accessible only within the integrated circuit. The integrated circuit further includes component- specific hardware interfaces for connecting the individual discrete components to the selected pre-defined internal HDL interfaces. The component-specific hardware interfaces are designed individually for the different discrete computer components to interface the discrete components to the internal hardware interfaces. A development system is disclosed for use during development of such a computer system. The development system includes interconnections that allow functions to be easily moved from the integrated circuit to a system CPU.
