摘要： An embedded ROM-based processor system including a processor, system memory, a programmable memory, a data selector and a patch controller. The system memory includes a read-only memory (ROM). The programmable memory stores patch information including patch code and one or more patch vectors. Each patch vector includes a break-out address from the ROM and a patch-in address to a corresponding location within the patch code. The data selector has an input coupled to the system memory and an output coupled to the processor. The patch controller is operative to compare an address provided by the processor with each break-out address to determine a breakout condition, and to control the selector to transfer the processor to a corresponding location within the patch code in response to a break-out condition. The programmable memory may be volatile memory, where the patch information is loaded from an external memory during initialization.

摘要： A host-side wireless interface services communications between a wireless user input device and a serviced host. The host-side wireless interface includes a wireless network interface, a host interface, and may include additional components. The wireless network interface wirelessly communicates with the wireless user input device. The host interface communicatively couples to the wireless interface and to the serviced host. When the serviced host initiates bootstrap operations via a Basic Input/Output System (BIOS), the host interface operates in a BIOS host interface mode to allow input from the wireless user input device to the BIOS during the bootstrap operations. Further, when the serviced host initiates Operating System (OS) operations, the host interface operates in an OS host interface mode, wherein the OS host interface mode differs from the BIOS host interface mode. In this fashion, the user of the wireless user input device may interface with the BIOS during booting operations prior to loading and configuration of the OS.

摘要： Timing vectors are used to pass execution of time-dependent operations from firmware/software to a hardware component (e.g., a state machine). These vectors may be stored as a vector table in a data memory that is accessible by both the firmware/software and the hardware component. Based on the processing being performed in the system, the firmware/software will determine that one or more operations are to be performed at a certain time. The firmware/software stores a reference to that time and the operation(s) in a vector. The hardware component monitors time in the system and the vectors to determine whether the current time matches the time associated with a given vector. When there is a match, the hardware component causes the operation(s) associated with the vector to be performed. The system also may perform different operations at a given time depending on the operating condition (e.g., state) of the system.

摘要： An embedded processor system including at least one gated power unit including an internal ROM and a power controller that provides one or more gated power signals to selectively provide power to each gated power unit. The power controller provides a gated clock signal to the embedded processor to selectively control power consumption of the processor. The power controller powers down each gated power unit after freezing the processor and then powers up each gated power unit before reactivating the processor. The embedded processor system may include isolation circuitry, such as clamp circuitry or the like, that is operative to minimize current flow into each gated power unit when powered down. The gated power units may include a static function. The ROM of an embedded ROM-based microprocessor system is powered down when the microprocessor is idle to reduce or otherwise eliminate intrinsic leakage.
