摘要： A structure and associated method of processing data on a semi-conductor device comprising an input island, a processing island, and an output island formed on the semiconductor device. The input island is adapted to accept a specified amount of data and enable a means for providing a first specified voltage for powering the processing island after accepting the specified amount of data. The processing island is adapted to receive and process the specified amount of data from the input island upon powering the processing island by the first specified voltage. The output island is adapted to be powered by a second specified voltage. The processing island is further adapted to transmit the processed data to the output island upon said powering by the second specified voltage. The first specified voltage is adapted to be disabled thereby removing power from processing island upon completion of transmission of the processed data to the output island.

摘要： A circuit for fencing input signals to circuits in a voltage island when switching between a normal and a standby power supply is disclosed. A voltage detector detects the switch over in power source and generates a power switch signal. The power switch signal is synchronized to a standby clock and a normal clock. The synchronized standby clock signal is delayed by a counter to allow circuit stabilization. The normal and standby clock signals are logically combined and used to fence input signals to the circuits on the voltage islands.

摘要： A programmable, timing signal generator propagates a digital wave along a delay chain comprised of series connected inverters that has sufficient stages that the edge of the wave will not propagate to the end during one system clock cycle time. The delay chain is sampled once each clock cycle, and the point to which the wave has progressed is encoded. Programmable, fine leading and fine trailing edge registers store, as a fraction of the clock cycle time, the desired locations of the timing signal leading and trailing edge relative to the clock edges.

摘要： The invention provides for selectively changing a line width for a memory, i.e., selecting one of a plurality of line widths for a memory. The selected line width is used in communicating with one or more processors. This provides increased flexibility and efficiency for communicating with the memory. In particular, a register can be set based on a desired line width, and subsequently used when locating data in the memory. The selected line width can be associated with each data block in the memory to allow multiple line widths to be used simultaneously. When implemented in a cache, multiple ways of the cache can be processed as a group to provide data during a single memory operation. The line width can be varied based on a task, a processor, and/or a performance evaluation.
摘要翻译：本发明提供了选择性地改变存储器的线宽，即选择存储器的多条线宽之一。选择的线宽用于与一个或多个处理器进行通信。这提高了与内存通信的灵活性和效率。特别地，可以基于期望的线宽来设置寄存器，并且随后在将数据定位在存储器中时使用。所选线宽可以与存储器中的每个数据块相关联，以允许同时使用多个线宽。当在缓存中实现时，高速缓存的多种方式可以被处理为一组以在单个存储器操作期间提供数据。线宽可以根据任务，处理器和/或性能评估而变化。
