Methods and apparatus for adaptive power profiling in a baseband processing system. In an exemplary embodiment, an apparatus includes one or more processing engines. Each processing engine performs at least one data processing function. The apparatus also includes an adaptive power profile (APP) and a job manager that receives job requests for data processing. The job manager allocates the data processing associated with the job requests to the processing engines based on the adaptive power profile. The adaptive power profile identifies a first group of the processing engines to perform the data processing associated with the job requests, and identifies remaining processing engines to be set to a low power mode.

Methods and apparatus for simultaneous multiprotocol processing of different radio standards using a common pipeline. In an exemplary embodiment an apparatus includes a plurality of wireless interfaces that transmit radio data symbols, a scheduler that outputs scheduled events that control transmission of the radio data symbols using any wireless interface type and any radio protocol, and an event processor that processes the transmission events to transport the radio data symbols to selected wireless interfaces for over the air transmission using selected radio protocols.

A method utilizing a system encompassing a free pool buffer; a deadlock avoidance buffer; and a controller communicatively coupled to the free pool buffer and the deadlock avoidance buffer to reorder out-of-order responses to fetch requests into correct order by: receiving a fetch request on behalf of a consumer; allocating space first in the free pool buffer and when such space is not available then allocating space in a division associated with the consumer in the deadlock avoidance buffer. Issuing segment(s) of the fetch request including associated tag(s) to one of one or more memories; writing response data for each of the segment(s) to the allocated space in the free buffer or the deadlock avoidance buffer according to each of the associated tag(s); and transferring the response data to the consumer according to an entry in an ordering first-in, first-out buffer and an entry in a pending request array.

A method and a system embodying the method for job pre-scheduling in a processing system comprising distributed job management, encompassing: determining a maximum amount of pre-schedulable jobs for each of a plurality of engines; setting for each of the plurality of engines a threshold less than or equal to the maximum amount; pre-scheduling by a scheduler an amount of jobs less than or equal to the threshold to at least one of a plurality of job managers; determining at the at least one of the plurality of job managers managing one of the plurality of engines one of a plurality of data processing devices in order for each pre-scheduled job; and assigning the job to the determined data processing device.

A method and a system for port access management at a distributed job manager, encompassing: initializing a port access process for each of one or more ports on a processing device; determining first whether a job is assigned to an active slot identified by an active_slot_id on the processing device, and when the determining is positive: determining second whether the job has been serviced by a port identified by the active_slot_id; and when either the first determining is negative or the second determining is positive then: retesting the first and second determining; else: determining whether the job requires an access to the port identified by the active_slot_id; and when the determining is positive: fetching the port's configuration words; processing the fetched port's configuration words; marking the job as serviced by the port upon conclusion or the processing of the fetched port's configuration words; and recalculating the value of the active_slot_id.

A method for fabricating opto-electronic devices having a surface that includes a first mirror facet in a first semiconductor layer deposited on a wafer. The mirror facet is located in a first facet plane. In the method of the present invention, the wafer is divided along a first line to create a segment having the mirror facet located therein. The segment is fixed to a fixture that moves in relation to a dicing disk that has a first planar surface in which polishing grit is embedded. The segment is fixed to a mounting surface such that the first plane is aligned parallel to the first planar surface of the dicing disk. The dicing disk is caused to rotate while the first planar surface is in contact with the segment, but not in contact with the mounting surface, thereby polishing a surface of the segment. For opto-electronic devices that include a second mirror facet in a second facet plane, the second facet plane being parallel to the first facet plane and displaced therefrom, the wafer is also divided along the second line such that the segment also includes the second facet plane. The second mirror surface is polished by causing the dicing disk to rotate while the second planar surface is in contact with the segment along the second line. The present invention can be practiced with a conventional dicing saw.
