Some bus protocols are useful for management of peripheral devices that exist on a computer's system bus. Such bus protocols include the industry standard architecture bus (ISA), peripheral component interconnect (PCI), PCI express (PCIe), etc. The usefulness of such protocols for control messages, interrupt management and more is limited to the short distances over which the protocols operate, usually measured in inches. The use of longer distance transport protocols, such as Ethernet to encapsulate and transport bus protocol messages allows the advantages of the short distant protocols to be used to control remote devices. A master device, with a controller or processor, may be used to manage the operation of a slave device using the bus or control protocol. Such management may include button presses, indicator lights, slave device configuration, etc. The slave device may have a low cost controller or ASIC to provide real-time operational functions, such as routing.

An electronic Input/Output Interface and device abstraction system used in gaming machine includes: a game central processing unit (the game “CPU”); an intelligent Input/output controller board (the “IOCB”); an Industry Standard Architecture PC bus (“IBA bus”); and a framed message transport protocol. The IOCB facilitates the communications between the game CPU and virtual device services, which, are peripheral devices associated with the gaming system. These include devices such as displays, buttons, hoppers, coin mechanisms and bill validators. The framed message transport protocol includes: a message header, a body containing a virtual device message, and a packet validation signature. The game CPU communicates to gaming peripherals by sending virtual device messages across the ISA bus to the IOCB. The IOCB then routes the virtual device message to the appropriate virtual device services. The virtual device services are responsible for handling specific hardware, and are made up of virtual device drivers on the game CPU that communicate with virtual devices on the IOCB and use of the IOCB and the high speed interface enables the game CPU to use more of its available functions for controlling gaming functions rather than one operation of its associated peripheral devices.

A portable device is connected to a host system that operates according to a first industry standard architecture (e.g., a personal computer built according to the IBM Personal Computer standard). The user initiates a session in the host system using the software and data in the portable device. The user suspends the state of the session, the state is stored in the portable device, and the user disconnects the portable device from the host. The user later connects the portable device to a second host that operates according to a second industry standard architecture (e.g., Apple Macintosh™ computer). The second host boots an autoconfiguring host operating system stored in the portable device and starts a virtual machine layer also stored in the portable device. The user then resumes operation of the suspended virtual machine layer session.

Apparatus and techniques for performing JTAG testing on production devices and systems through industry standard interfaces. The devices employ processors configured to receive packetized test input data from a tester over a standard communication interface such as a USB or Ethernet port and perform associated testing operations defined by the test input data, such as JTAG-compliant testing. This is facilitated, in part, via use of a bridge and one or more DFx handlers, with the bridge operating as an interface between the DFx handlers and a bus and/or interconnect over which test input and result data is transferred via the standard communication interface. The techniques enable testing such as JTAG testing to be performed on fully-assembled devices and systems without requiring the use of dedicated test or debug ports.

Disclosed is a method of recognizing a process in a full-system Industry Standard Architecture (ISA) emulator, comprising the steps of: recognizing a process based on a base address of a page table thereof, recognizing the switch between the processes when said base address of the page table has changed, recognizing the termination of a recorded process when the base address of the page table of the process which tries to modify the page table is not equal to the base address of the page table of the recorded process in the page table. With the recognized process, the binary translation results indexed based on content can be saved into a corresponding process repository, thereby achieving the permanent saving of the translation results and the reuse of translation and optimization on the basis of a previously executed program. Consequently, the overall performance of the full-system Industry Standard Architecture emulator is enhanced.
