摘要： A selectable control over multiple clock frequency/voltage level combinations that can be activated in a processor. A table can be placed in hardware that defines multiple combinations of CPU clock frequency and CPU operating voltage. By placing the table in hardware, it can be assured that all the various combinations will work for the particular processor device. Software can then be used to select a combination from this table, to control the actual frequency/voltage combination that is being implemented at a given time. This allows dynamic control over the power/performance tradeoff, so that the system can see maximum power savings consistent with acceptable performance, as operating and environmental considerations continue to change the most desirable selections.

摘要： A power control circuit an corresponding technique for adjusting operating frequency and/or supply voltage in sections of a single electronic device while maintaining substantially constant operating frequency and/or supply voltage in the other sections in the electronic device. Such control is based on the operating environment of the hardware product employing the electronic device by determining whether the hardware product is connected to an external power source. As a result, the electronic device in the hardware product is able to operate at full frequency and voltage during certain situations and to operate at a reduced frequency and/or voltage in some sections of the processor and not in the other sections during other situations.

摘要： Techniques are described that can be used to ensure ordered computation and/or retirement of threads in a multithreaded environment. Threads may contain bundled instances of work, each with unique ordering restrictions relative to other instances of work packaged in other threads in the system. When applied to 3D graphics, video and image processing domains allow unrestricted processing of threads until reaching their critical sections. Ordering may be required prior to executing critical sections and beyond.

摘要： A scaling circuit residing on a single silicon substrate includes a buffer for storing a plurality of partially scaled data. A multiplier is provided for multiplying a weight signal with each of a plurality of input data to produce a plurality of weighted data. An adder is coupled to (1) the multiplier and (2) the buffer for adding each of the weighted data to one of the partially scaled data to produce a plurality of scaled data. When a first one of the scaled data is produced by the adder, the first one of the scaled data can remain in the buffer until displaced by a new data to be scaled such that the scaling circuit is directly coupled to an external bus without requiring any external buffering memory coupled in between. A method for scaling a block of data and transferring the scaled data to the bus is also described.

摘要： Input/output sample correlation is achieved through the use of first and second correlation tags appended to input and output buffers, respectively. As an output buffer of output samples is prepared, the first correlation tag identifies one of tie output samples in that buffer. As input samples are input and placed into an input buffer, a second correlation tag is appended to the input buffer which identifies the input sample that is input at the time the output sample identified by the first correlation tag is output. Accordingly, a correlation between input and output samples can be used in an echo cancellation operation or the like.
摘要翻译：通过分别使用附加到输入和输出缓冲器的第一和第二相关标签来实现输入/输出样本相关。当输出样本的输出缓冲器被准备好时，第一个相关标签识别该缓冲器中的一个输出样本。当输入样本被输入并被放置到输入缓冲器中时，第二相关标签被附加到输入缓冲器，该输入缓冲器标识在输出由第一相关标签识别的输出样本时输入的输入样本。因此，可以在回波消除操作等中使用输入和输出样本之间的相关性。

摘要： An integrated circuit, for use as a cache subsystem, implements a cache static random access memory (SRAM) storage array, a central processor unit (CPU) bus interface and a main memory bus interface. The CPU bus and main memory bus interfaces include multiplexers, buffers, and local control for optimizing burst read and write operations to and from the CPU bus. These circuits allow a full cache line to be read or written in a single access of the SRAM array. Control logic is utilized within the CPU bus interface for controlling CPU bursts in the order defined by the CPU. The memory bus interface includes internal buffers used in performing memory bus reads, write-throughs, write-backs and snoops. Tracking logic is employed for determining the appropriate internal buffer to be utilized for a particular memory bus cycle. Additionally, a data path is included for transparently passing data between the CPU and memory bus interfaces without disturbance of the SRAM array.
