Abstract: Un procedimiento para la generación de al menos un segmento de informaciones sensibles al tiempo a través de un sistema de comunicación de voz sobre datos inalámbrico, utilizado en combinación con un protocolo de datos definido de antemano, que comprende: la definición de un tamaño de segmento mínimo para las informaciones que van a ser transmitidas; la definición de un tamaño de segmento máximo para las informaciones que van a ser transmitidas, siendo dicho tamaño de segmento máximo mayor que dicho tamaño de segmento mínimo; la generación de un primer segmento de informaciones (310) sensibles al tiempo si puede disponerse de una cantidad suficiente de dichas informaciones sensibles al tiempo para su transmisión, teniendo dicho primer segmento un tamaño de segmento entre dicho tamaño de segmento mínimo y dicho tamaño de segmento máximo; y caracterizado por la generación de un segundo segmento de informaciones (306) sensibles al tiempo que tengan un tamaño de segmento menor que o igual a dicho tamaño de segmento máximo tras la recepción de un mensaje de acuse de recibo procedente de un receptor, en el que el primer tamaño de segmento es diferente del segundo tamaño de segmento, y en el que el segundo tamaño de segmento no está limitado por el tamaño de segmento mínimo.

Abstract: A method and apparatus for efficient data transmission in a wireless voice-over-data communication system. In a transmitter, data segments are transmitted in accordance with a predefined data protocol. The predefined data protocol is modified to define a first segment size and a second segment size. The first segment size represents a minimum segment size that can be transmitted. The second segment size represents a maximum segment size that can be transmitted. A segment is created and transmitted whenever a quantity of time-sensitive information available for transmission allows a segment to be constructed having a segment size between the minimum segment size (308) and the maximum segment size. A segment of any size up to the maximum segment sizes is also created (306) and transmitted whenever any time-sensitive information is available for transmission and an acknowledgement message is received (304) by the transmitter.

Abstract: A three-dimensional (3D) graphics pipeline which processes pixels of sub- screens in the last stage (pixel rendering) in parallel and independently. T he sub-screen tasks are stored in a list in a shared memory. The shared memo ry is accessed by a plurality of processing threads designated for pixel ren dering. The processing threads seize and lock sub-screens tasks in an orderl y manner and process the tasks to create the bit map for display on a screen . The tasks are created by dividing a display area having the vertex informa tion superimposed thereon into MxN sub-screen tasks. Based on system profili ng, M and N may be varied.

Abstract: A method and apparatus for reducing voice latency in a voice-over-data wireless communication system. In a transmitter, data frames are created from audio information by a vocoder and stored in a queue. Prior to storage, some of the data frames are eliminated, or dropped, and are not stored in the queue. In a receiver, data frames are generated from received signals and stored in a queue. Prior to storage in the receiver queue, some of the data frames are dropped. Data frames are dropped either at a single fixed rate, a dual fixed rate, or a variable rate, generally depending on a communication channel latency. By dropping data frames at the transmitter, the receiver, or both, voice latency due to data frame retransmissions is reduced.

Abstract: Resource management techniques in multi-processor systems are described. Embodiments include a multi-processor system having a primary processor for communication with pipelined secondary processors. The secondary processors include registers containing status information for tasks executed by the respective secondary processors. The primary processor is provided with direct access to contents of the registers and manages computational and memory resources of the multi-processor system based on the acquired status information.

Abstract: A METHOD AND APPARATUS FOR REDUCING VOICE LATENCY IN A VOICE-OVER-DATA WIRELESS COMMUNICATION SYSTEM . IN A TRASNMITTER (400), DATA FRAMES ARE CREATED FROM AUDIO INFORMATION BY A VOCODER (406) AND STORED IN A QUEUE (408).PRIOR TO STORAGE, SOME OF THE DATA FRAMES ARE ELIMINATED, OR DROPPED, AND ARE NOT STORED IN THE QUEUE (408). IN A RECEIVER (600), DATA FRAMES ARE GENERATED FROM RECEIVED SIGNALS AND STORED IN A QUEUE (612). PRIOR TO STORAGE IN THE RECEIVER QUEUE (612), SOME OF THE DATA FRAMES ARE DROPPED. DATA FRAMES ARE DROPPED EITHER AT A SINGLE FIXED RATE, A DUAL FIXED RATE, OR A VARIABLE RATE, GENERALLY DEPENDING ON A COMMUNICATION CHANNEL LATENCY.BY DROPPING DATA FRAMES AT THE TRANSMITTER (400), THE RECEIVER (600), OR BOTH (400,600), VOICE LATENCY DUE TO DATA FRAME RETRANSMISSION IS REDUCED.(FIG 7)
