A steganographic embedder associates data with an image by encoding the data, a link to the data, or a combination of both into the image. The embedder may be located in an image capture device or an external process or device. In one application, for example, an embedder process steganographically encodes data into an image as part of the process of uploading the image from the image capture device to external storage.

An embedded user interface incorporated into a gaming device, the gaming device including a gaming presentation of a base game and a gaming processor for controlling the base game. The embedded user interface includes: a player tracking interface and an embedded processor. The player tracking interface includes (or is associated with) a display screen and enables display of a system game to a user, presentation of information to the user, and reception of information from the user. The embedded processor employs an internal operating system and communicates with the gaming processor, enables control of the system game, control of player tracking information, and control of non-gaming information. In one embodiment, the embedded user interface enables control of a system game of which at least a portion of the system game is presented physically external to the embedded user interface. In another embodiment, the embedded user interface enables control of a system gaming indicator that is physically external to the embedded user interface. In still another embodiment, communication between a game processor and an embedded user interface is only enabled through the gaming network and is not direct enabled via a direct connection.

An apparent network interface permits one processor such as a processor embedded within a larger processing system (an embedded processor) to communicate to a host processor or other processors and devices on the network to which the embedded processor is attached, using standard network communication mechanisms / protocols such as TCP / IP, NFS, FTP, HTTP, etc. The web server protocol HTTP is particularly useful because it permits the embedded computer to publish a user interface for remote monitoring and remote control using a standard web browser application. The invention provides the host computer with an apparent network interface that appears to be a standard network device, such as an Ethernet interface card. This apparent interface communicates directly with the embedded processor, which appears to be a device on this apparent network. Significant cost savings and performance enhancements are realized by implementing the communication directly over the host computer's peripheral bus rather than using standard network hardware such as Ethernet hardware.

A service management system for devices with embedded processor systems manages use of memory by programs implementing the services by assigning services to classes and limiting the number of services per class that can be loaded into memory. Classes enable achieving predictable and stable system behavior, defining the services and service classes in a manifest that is downloaded to embedded devices operating on a network, such as a cable or satellite television network, telephone or computer network, and permit a system operator, administrator, or manager to manage the operation of the embedded devices while deploying new services implemented with applications downloaded from the network when the service is requested by a user.

A reconfigurable test system including a host computer coupled to a reconfigurable test instrument. The reconfigurable test instrument includes reconfigurable hardware-i.e. a reconfigurable hardware module with one or more programmable elements such as Field Programmable Gate Arrays for realizing an arbitrary hardware architecture and a reconfigurable front end with programmable transceivers for interfacing with any desired physical medium-and optionally, an embedded processor. A user specifies system features with a software configuration utility which directs a component selector to select a set of software modules and hardware configuration files from a series of libraries. The modules are embedded in a host software driver or downloaded for execution on the embedded CPU. The configuration files are downloaded to the reconfigurable hardware. The entire selection process is performed in real-time and can be changed whenever the user deems necessary. Alternatively, the user may create a graphical program in a graphical programming environment and compile the program into various software modules and configuration files for host execution, embedded processor execution, or programming the reconfigurable hardware.

A hardware virtual machine instruction processor directly executes virtual machine instructions that are processor architecture independent. The hardware processor has high performance; is low cost; and exhibits low power consumption. The hardware processor is well suited for portable applications. These applications include, for example, an Internet chip for network appliances, a cellular telephone processor, other telecommunications integrated circuits, or other low-power, low-cost applications such as embedded processors, and portable devices.

A programmable logic integrated circuit has an embedded processor with a watchdog timer circuit. The watchdog timer circuit is used to detect software or hardware failures. In one implementation, the watchdog timer circuit includes a counter register that advances (e.g., incremented or decremented) with each clock. To prevent the watchdog timer circuit from becoming triggered, the watchdog timer circuit should be reset or reloaded by software. For example, the count register may be reset to a value to start the count over. If the count register is allowed to count to a final or maximum value, the watchdog timer circuit will become triggered, generating a triggered signal that causes the programmable logic integrated circuit to be reset. A reset causes a reloading of the configuration data used to program the programmable logic and embedded processor portions of the integrated data. The configuration data may be stored in an external nonvolatile storage memory.

First (embedded) and second (non-embedded) processors are energized by an energy source in a hand-held device. The second processor performs functions requiring more power than those performed by the first processor. The second processor is normally asleep and is awakened by the first processor and is empowered, when awakened, to perform functions. Only the portions of the second processor required to perform these functions are activated. Protocols for functions to be performed by the second processor are provided initially to the second processor and are processed in the second processor. They are then transferred to the first processor for storage. When the second processor is activated to perform functions represented by a protocol, the protocol is transferred to the second processor and the functions are performed by the second processor.

A parallel processing architecture comprising a cluster of embedded processors that share a common code distribution bus. Pages or blocks of code are concurrently loaded into respective program memories of some or all of these processors (typically all processors assigned to a particular task) over the code distribution bus, and are executed in parallel by these processors.

The processors within the cluster preferably share a common memory (1 per cluster) that is used to receive data inputs from, and to provide data outputs to, a higher level processor. Multiple interconnected clusters may be integrated within a common integrated circuit device.
