摘要： An electronic casino gaming system includes an unalterable ROM for storing a casino game authentication program, including a message digest algorithm program, a decryption program and a decryption key. A casino game data set containing casino game rules and image data is stored in a mass storage device, such as a local disk memory or a remote network file server, along with the signature of the casino game data set. The signature is an encrypted version of the message digest of the casino game data set, prepared using a hash function. Prior to permitting game play by a player, the casino game data set is transferred from the mass storage device to main memory and during this process the message digest is computed from the image data using a hash function stored in the ROM. The encrypted version of the message digest transferred from the mass storage device is decrypted using the decryption program and decryption key stored in the unalterable ROM. The two message digests are then compared for a match: if a match exists, game play is permitted; if a match does not exist, game play is prohibited. The authentication procedure is also used to check all casino game software, both programs and fixed data sets, stored in any memory devices distributed throughout the system, such as the system boot ROM, NVRAM and all sub-system memory devices. The authentication procedure is run whenever a particular program or fixed data set is scheduled for use by the system, and also at periodic intervals and on demand.

摘要： Circuits, methods, and apparatus for slowing clock circuits on a graphics processor integrated circuit in order to reduce power dissipation. An exemplary embodiment of the present invention provides a graphics processor having two memory clocks, specifically, a switched memory clock and an unswitched memory clock. The switched memory clock frequency is reduced under specific conditions, while the unswitched memory clock frequency remains fixed. In a specific embodiment, the switched memory clock frequency is reduced when related graphics, display, scaler, and frame buffer circuits are not requesting data, or are such data requests can be delayed. Further refinements to the present invention provide circuits, methods, and apparatus for ensuring that the switched and unswitched memory clock signals remain in-phase and aligned with each other.

摘要： A plurality of processing elements independently operate in parallel on separate streams of data but in response to common instructions. In order to selectively and individually enable each processing element, a control register stage is provided for each. Each register may be controlled, as between its enabling and disabling states with respect to execution of a common instruction, by the results of a test performed by its associated processor in response to a prior instruction and by the complement of the test results. The system is especially adapted to support flow of control operators, such as IF/THEN constructs, IF/THEN/ELSE constructs and WHILE/DO loop constructs.

摘要： Circuits, methods, and apparatus for reducing power on a graphics processor integrated circuit by generating two memory clock signals, reducing the frequency of one under certain conditions, and maintaining the frequency of the other. To reduce skew and jitter between these two memory clocks, and to ensure that they remain in phase, a synchronizer circuit is used by an exemplary embodiment of the present invention. The synchronizer circuit is also useful as a general application clock generator.

摘要： Authentication of a casino game data set is carried out within the casino game console using an authentication program stored in an unalterable ROM physically located within the casino game console. The casino game data set and a unique signature are stored in a mass storage device, which may comprise a read only unit or a read/write unit and which may be physically located either within the casino game console or remotely located and linked to the casino game console over a suitable network. The authentication program stored in the unalterable ROM performs an authentication check on the casino game data set at appropriate times, such as prior to commencement of game play, at periodic intervals or upon demand. At appropriate occasions, the contents of the unalterable ROM can be verified by computing the message digest of the unalterable ROM contents and comparing this computed message digest with a securely stored copy of the message digest computed from the ROM contents prior to installation in the casino game console.
