Embodiment Construction

[0013] Various embodiments now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

[0014] refer to figure 1 , many electronic designs 10 can be represented in their basic form by two schematic components, a main logic board (MLB) (“mainframe”) 12 and an option board 14 . It is an object of the present invention to equip an MLB host with a configurable interface so that although option boards require multiple interface configurations, the board can connect to the MLB host and function correctly by calling only the host configuration routines that control the configurable interface.

Abstract

The present invention relates to a main logic board having an electrically configurable option board interface (ECOBI) to facilitate connection of an option board to a device for providing option functions. Once connected to the host, the option board provides identification (ID) data to the main logic board host processor. The host processor determines the interface configuration necessary to enable communication between the host and the option board based on the option board ID, and then configures the electrically configurable interface circuitry for operational compatibility. Option boards provide interface drivers directly to the host to configure the interface. The interface may include a standard interface protocol such as PCI or USB configured by the host through the same connection to the option board.

Description

technical field [0001] The present invention relates to the field of electrical and electronic design, and more particularly to an electrically configurable interface for a host, configurable in hardware and / or software to accommodate various interfaces present on option boards connected to the host. Background technique [0002] Option boards used to increase functionality in a system are usually limited to fixed electrical interfaces through specific components used or specific electrical standards designed by IEEE or other standards bodies (e.g., Peripheral Component Interconnect - PCI) Regulation. These not only limit the electrical voltage levels, signaling formats and software protocols that can be used across the interface, but also the exact type of components used in connection with that interface. If an option board can be incorporated into a system that is able to adapt the interface between the system and the option board independently of the interface configura...
