Patent number: 8428512Abstract: A method and system sharing a Bluetooth processor for FM functions are provided. The single chip may comprise an integrated Bluetooth radio, an integrated FM radio, and processor system. A processor in the processor system may be utilized for Bluetooth and FM data processing and may time multiplex between the Bluetooth and FM data processing based on interrupt signals. The processor may operate in a low power mode based on a clock signal generated from a low power oscillator. When a Bluetooth interrupt signal is received, the processor may enable Bluetooth data processing that may be based on a Bluetooth clock signal. When an FM interrupt signal is received, the processor may enable FM data processing that may be based on an FM clock signal. When data processing is complete, the processor may return to the low power mode operation.Type: GrantFiled: November 22, 2005Date of Patent: April 23, 2013Assignee: Broadcom CorporationInventors: Brima Ibrahim, Mitchell Buznitsky, John Walley, Ahmadreza Rofougaran, Bojko Marholev, Angel Polo, Asif Grushkevich

Patent number: 7587189Abstract: 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.Type: GrantFiled: October 25, 2005Date of Patent: September 8, 2009Assignee: Broadcom CorporationInventors: Mitchell A.

Patent number: 7039776Abstract: 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.Type: GrantFiled: April 17, 2003Date of Patent: May 2, 2006Assignee: Broadcom CorporationInventors: Yuqian C.
