    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.

    摘要: Determination and processing for fractional-N programming values. The present invention is operable to receive a clock signal (CLK) and to transform that CLK into a new CLK, when necessary, for use by various circuitries within a system. The present invention is operable to generate two different CLKs for use by a radio frequency (RF) circuitry and a baseband processing circuitry in certain embodiments. The present invention employs a measurement circuitry and to characterize a first CLK and uses a fractional-N synthesizer to perform any necessary processing to generate the one or more CLKs to the other CLKs within the system. The first CLK may be received from an external source or it may be generated internally; in either case, the present invention is able to modify the CLK into another CLK for use by other circuitries within the system or for use by another external device.

    摘要: A dual-mode BLE device identifies idle intervals within Bluetooth BR/EDR traffic communications. The identified idle intervals are used by the dual-mode BLE device to concurrently perform various BLE activities. For example, advertising packet transmissions, advertising packet scanning, connection setup, and/or data packet communication may be concurrently performed within identified idle intervals within the Bluetooth BR/EDR traffic communications. Packet transmission timing, advertising interval, scan window, and/or packet size are determined based on the identified idle intervals within the Bluetooth BR/EDR traffic communications. A scan window is adjusted based on timing of expected advertising transmissions and/or advertising interval(s) for saving power. BLE packets and Bluetooth BR/EDR packets may be detected in a single advertising channel. Maximal payload size is set based on the identified idle intervals within Bluetooth BR/EDR traffic communications. As a slave, the dual-mode BLE device updates connection parameters based on the identified idle intervals within Bluetooth BR/EDR traffic communications.

The processors and/or circuits may be operable to determine a transmitted signal power level based on the determined maximum input level. The processors and/or circuits may be operable to transmit subsequent signals via a distinct Bluetooth connection based on the determined transmitted signal power level. The data rate for signal transmission via the distinct Bluetooth connection may exceed the data rate for signal transmission via the BR connection and the data rate for signal transmission via the EDR connection.

    摘要: Aspects of a method and system for multi-radio coexistence and a collaborative interface may include exchanging information between a plurality of radio transceivers integrated within a single device to enable coexistence, and coordinating sharing of transmit and receive resources between the plurality of radio transceivers by controlling access to the transmit and receive resources, where any one of the plurality of radio transceivers may be enabled to be selected to control the access based on the exchanged information. Selecting one of the radio transceivers for the controlling of the access band may be based on processing capability or priority of communication. The resources may comprise frequency bands, time slots, and antenna access. The information may be exchanged via a serial bus between the plurality of radio transceivers, where the serial bus may conform to an I2C (I-square-C) multi-master serial bus. Each of the radio transceivers may conform to one or more radio frequency technology.
