Appl. No.:

10/007435

Inventors:

John Lin - Downey CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04B 7/00
H04Q 7/20

US Classification:

455 412, 455507, 455514, 455517

Abstract:

A baseband controller includes a microsequencer that is formed to include special hardware resources and a configuration that facilitates using the micro-sequencer as a real-time baseband controller. The microsequencer includes a 72-bit correlator that way also be used as an accumulator. The correlator is able to communicate with a 72-bit arithmetic logic unit, enabling the correlator to act as an accumulator, as well as a plurality of clocks and timers that facilitate the timing functionality to satisfy Bluetooth specifications. More specifically, the microsequencer includes at least four clocks and eight times. The four clocks include an externally driven Bluetooth clock, an externally driven real-time clock, a native Bluetooth clock and a native real-time clock. The microsequencer further includes at least four registers for temporarily storing computational data. The storage registers have different sizes for storing different sized packets of computational data.

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04J 1/16
H04J 3/14

US Classification:

370230, 370235

Abstract:

A baseband controller system creates and maintains a schedule of synchronized events and reviews the schedule as a part of determining whether to initiate a transmission of a non-synchronous event. One aspect is to avoid a possibility of collision between synchronized and non-synchronized communication events. The schedule of synchronized events are evaluated in relation to the present time and determine whether a non-synchronized event may be transmitted without the likelihood of a collision. The transmission determination includes evaluating future time periods to see if a synchronized event is scheduled during a time period in which the non-synchronized event would continue to be transmitted for those non-synchronized events that span two or more defined time periods in length.

International Classification:

H04B 7/00

US Classification:

455 412, 455 413, 455507, 455514, 455517

Abstract:

A baseband controller includes a microsequencer with special hardware resources circuitry and a configuration that supports real-time Bluetooth functionality for an upper limit of Bluetooth slave devices. The microsequencer includes a 72-bit correlator that may also be used as an accumulator, wherein the topology provides that the correlator can communicate with a 72-bit arithmetic logic unit that correspondingly enables the correlator to act as an accumulator. The microsequencer also includes a plurality of clocks and timers for facilitating Bluetooth timing functionality, and at least four registers for temporarily storing computational data, where each of the storage registers have different sizes for accommodating different-sized packets of computational data.

International Classification:

US Classification:

370347, 3703954, 370468, 370346, 4554521

Abstract:

A baseband controller system creates and maintains a schedule of synchronized events and reviews the schedule as a part of determining whether to initiate a transmission of a non-synchronous event (one that is not time sensitive, for example, e-mail). One aspect of the present invention is to create a system and method that avoids a possibility of collision between synchronized and non-synchronized communication events. A synchronized event is a scheduled transmission of time sensitive data such as what is often known as continuous bit rate data. Examples include video and voice wherein a collision (inability to transmit the continuous bit rate data) may result in degradation of signal quality at the receiving end. The inventive system and method evaluate the schedule of synchronized events in relation to the present time and determine whether a non-synchronized event may be transmitted without the likelihood of a collision. Making the determination that such a transmission may occur includes evaluating future time periods to see if a synchronized event is scheduled during a time period in which the non-synchronized event would continue to be transmitted for those non-synchronized events that span two or more defined time periods in length.

International Classification:

H04B 1/06

US Classification:

455259, 375372, 711100

Abstract:

A microprocessor system architecture is disclosed which allows for the selective execution of programmed ROM microcode or, alternatively, RAM microcode if there has been a correction or update made to the ROM microcode originally programmed into the system. Patched or updated RAM microcode is utilized or executed only to the extent of changes to the ROM microcode, otherwise the ROM microcode is executed in its normal fashion. When a patch is received, it is loaded into system RAM along with instructions or other appropriate signals to direct the execution of the patched or updated microcode from RAM instead of the existing ROM microcode. Various methods are presented for selecting the execution of the appropriate microcode depending upon whether there have been changes made to it.

US Classification:

370466, 370401, 370463, 370469

Abstract:

A method and apparatus for implementing a protocol-neutral middleware interface in a home area network. The method comprises receiving one or more data packets from a client device using a first communication protocol, and decoding the data packets into a set of platform independent data objects. The data packets are decoded into the platform independent data objects by utilizing a metadata mapping located within one or more field classes. The apparatus comprises a frame engine, and one or more field classes. The frame engine receives a data packet in a first communication protocol. The frame engine decodes the data packet into a set of platform independent data objects. The frame engine uses a metadata map contained within the one or more field classes to decode the data packet into the set of platform independent data objects.
