摘要： This disclosure describes techniques for coding mode selection using estimated coding costs. To provide high compression efficiency, for example, an encoding device may attempt to select a coding mode for coding blocks of pixels that codes the data of the blocks with high efficiency. To this end, the encoding device may perform coding mode selection based on estimates of coding cost for at least a portion of the possible modes. In accordance with the techniques described herein, the encoding device estimates the coding cost for the different modes without actually coding the blocks. In fact, in some aspects, the encoding module device may estimate the coding cost for the modes without quantizing the data of the block for each mode. In this manner, the coding cost estimation techniques of this disclosure reduce the amount of computationally intensive calculations needed to perform effective mode selection.

摘要： An apparatus for generating an oscillating signal that includes a circuit to accelerate the time in which an oscillating signal reaches a defined steady-state condition from a cold start. The apparatus includes an oscillating circuit to generate an oscillating signal; a first circuit to supply a first current to the oscillating circuit; and a second circuit to supply a second current to the oscillating circuit, wherein the first and second currents are adapted to reduce the time duration for the oscillating signal to reach a defined steady-state condition. The apparatus may be useful in communication systems that use low duty cycle pulse modulation to establish one or more communications channels, whereby the apparatus begins generating an oscillating signal at approximately the beginning of the pulse and terminates the oscillating signal at approximately the end of the pulse.

摘要： A mobile Communications device uses a method for determining position that involves a positioning filter, such as a Kalman filter, which is initialized with measurements from reference stations such as satellite vehicles and/or base stations which may be acquired during different epochs. Accordingly, the positioning filter may be used for position estimation without the need to first acquire at least three different signals during the same measurement epoch.

摘要： Methods and apparatus for communicating between an access terminal (AT) and a device serving the AT by way of an Access Point (AP) are described. In accordance with one feature serving devices may be assigned specific addresses which are interpreted based on the source of the communication, e.g., MAC packet, in which the address is used. Such addresses may be interpreted as being of a different type than other addresses which can be interpreted and/or used without taking into account the identity of the sender. In some embodiments Session Controllers and/or Internet Attachment Points (IAPs) are identified with such addresses. The address value is the same for one or more ATs but is interpreted at an AP receiving such the IAP address based on information corresponding to the AT which sent the packet including the IAP or Session Controller address.

摘要： A multi-threaded processor is provided that internally reorders output threads thereby avoiding the need for an external output reorder buffer. The multi-threaded processor writes its thread results back to an internal memory buffer to guarantee that thread results are outputted in the same order in which the threads are received. A thread scheduler within the multi-threaded processor manages thread ordering control to avoid the need for an external reorder buffer. A compiler for the multi-threaded processor converts instructions that would normally send processed results directly to an external reorder buffer so that the processed thread results are instead sent to the internal memory buffer of the multi-threaded processor.

摘要： Techniques for performing acquisition of packets are described. First detection values may be determined based on a first plurality of samples, e.g., by performing delay-multiply-integrate on the samples. Power values may be determined based on the first plurality of samples, e.g., by performing multiply-integrate on the samples. The first detection values may be averaged to obtain average detection values. The power values may also be averaged to obtain average power values. Whether a packet is presence may be determined based on the average detection values and the average power values. Second detection values may be determined based on a second plurality of samples. The start of the packet may be determined based on the first and second detection values. A third detection value may be determined based on a third plurality of samples. Frequency error of the packet may be estimated based on the first and third detection values.

摘要： Systems and methodologies are described that generate pilots for signal acquisition in a wireless communication system based on time domain sequences. The pilots may be generated by a base station and transmitted in a pilot field to one or more access terminals to aid in signal acquisition at each of the access terminals. One of the pilots may be common to all access points in the wireless communication system, thereby allowing an access terminal to obtain a timing estimate for the system while minimizing the effects of interference variations between base stations. Further, one or more generated pilots may be unique to each access point in order to allow each respective access point to be identified by its generated pilots.

摘要： Techniques for use in CDMA-based products and services, including replacing cache memory allocation so as to maximize residency of a plurality of set ways following a tag-miss allocation. Herein, steps forming a first-in, first-out (FIFO) replacement listing of victim ways for the cache memory, wherein the depth of the FIFO replacement listing approximately equals the number of ways in the cache set. The method and system place a victim way on the FIFO replacement listing only in the event that a tag-miss results in a tag-miss allocation, the victim way is placed at the tail of the FIFO replacement listing after any previously selected victim way. Use of a victim way on the FIFO replacement listing is prevented in the event of an incomplete prior allocation of the victim way by, for example, stalling a reuse request until such initial allocation of the victim way completes or replaying a reuse request until such initial allocation of the victim way completes.

摘要： Techniques for operating a receiver to achieve good linearity performance and higher receive signal to noise ratio are described. The receiver includes one or more circuit blocks, e.g., a low noise amplifier (LNA), having discrete gain states. The gain states are selected based on switch points, with each switch point indicating a specific received signal level at which to switch from one gain state to another gain state. The switch points may be dynamically selected based on channel conditions, which may be characterized by the presence or absence or strength or frequency of jammers. A first set of switch points may be selected when jammers are detected, and a second set of switch points may be selected when jammers are not detected. The gain states are selected in accordance with the set of switch points selected for use.
