    • A transmission method is used by a node of a communications network, wherein nodes communicate with one another via a carrier-sense multiple-access channel, said method comprising a step of sending a signal at a given transmit power and a given data rate to a receiver node over the channel, and wherein the transmit power of the sent signal assumes successively a first power value during a first time period and then a second power value during a second time period, the two power values being different and one of them being equal to the given power, the first time period representing the given power and the second time period representing the data rate. The invention also relates to a method of receiving a signal sent by the transmission method enabling the transmit power and the data rate used by the sender node to be deduced from the received signal.

    • A method for cleaning dirty data in an intermediate cache is disclosed. A dirty data notification, including a memory address and a data class, is transmitted by a level 2 (L2) cache to frame buffer logic when dirty data is stored in the L2 cache. The data classes may include evict first, evict normal and evict last. In one embodiment, data belonging to the evict first data class is raster operations data with little reuse potential. The frame buffer logic uses a notification sorter to organize dirty data notifications, where an entry in the notification sorter stores the DRAM bank page number, a first count of cache lines that have resident dirty data and a second count of cache lines that have resident evict_first dirty data associated with that DRAM bank. The frame buffer logic transmits dirty data associated with an entry when the first count reaches a threshold.
    • 公开了一种用于清除中间高速缓存中的脏数据的方法。 当脏数据存储在L2高速缓存中时,包含存储器地址和数据类的脏数据通知由级别2(L2)高速缓存发送到帧缓冲器逻辑。 数据类可能包括首先驱逐,最后驱逐正常和驱逐。 在一个实施例中,属于第一数据类别的数据是具有很少重用潜力的光栅操作数据。 帧缓冲器逻辑使用通知排序器来组织脏数据通知,其中通知分类器中的条目存储DRAM存储体页面编号,具有驻留脏数据的高速缓存行的第一计数和具有居民驱逐器的第一高速缓存行计数 与该DRAM库相关联的脏数据。 当第一计数达到阈值时,帧缓冲器逻辑发送与条目相关联的脏数据。
