    摘要: A static random access memory apparatus and a bit-line voltage controller thereof are disclosed. The bit-line voltage controller includes a controller, a pull-up circuit, a pull-down circuit and a voltage keeping circuit. The controller receives a bank selecting signal and a clock signal, and decides a pull-up time period, a pull-down time period and a voltage keeping time period according to the bank selecting signal and the clock signal. The pull-up circuit pulls up a bit-line power according to a first reference voltage within the pull-up time period. The pull-down circuit pulls down the bit-line power according to a second reference voltage within the pull-down time period. The voltage keeping circuit keeps the bit-line power to equal to an output voltage during the voltage keeping time period. The voltage keeping time period is after the pull-up time period and the pull-down time period.

    摘要: Different processor elements in multi-task/multi-core system on chip may have different memory requirements at runtime. The method for adaptively allocating cache memory re-allocates the cache resource by updating the bank assignment table. According to the associativity-based partitioning scheme, centralized memory is separated into several groups of SRAM banks which are numbered differently. These groups are assigned to different processor elements to be L2 caches. The bank assignment information is recoded in bank assignment table, and is updated by system profiling engine. By changing the information in bank assignment table, the cache resource re-allocation for processor elements is achieved.

    摘要: The present invention discloses a butterfly match-line structure and a search method implemented thereby, wherein the parallelism of the match lines is increased to shorten the search time, and a butterfly-type connection is used to reduce the power consumption and achieve the best energy efficiency. Via the butterfly-type connection, information can be reciprocally transmitted between the parallel match lines, which are independent originally. When a miss case occurs, more succeeding memory cells will not be compared but will be turned off. Thereby, the power consumption is reduced. Further, XOR-based conditional keepers are used to reduce the matching time and the power consumption. Besides, such a circuit is also used to shorten the delay time of the butterfly-type connection.

    摘要: The present invention discloses an XOR-based conditional keeper and an architecture implementing its application to match lines, wherein the XOR gate in the conditional keeper receives a clock signal synchronous with CAM (Content Addressable Memory) cells and cooperates with a floating signal from the floating node to create an XOR control signal, and the XOR control signal is transmitted to a P-type transistor to create a data signal to control the XOR-based conditional keeper so that the XOR-based conditional keeper can execute an appropriate corresponding action, which can replace the conventional keepers of merely “on” and “off” modes. Further, the XOR-based conditional keeper of the present invention can apply to the dynamic CAM match line architecture so that the dynamic match line can have lower power consumption, higher noise immunity, and high processing speed. Further, the XOR-based conditional keeper of the present invention can also apply to all kinds of dynamic circuits, particularly to a high fan-in circuit.

    摘要: An apparatus and method for providing high speed computing power with efficient power consumption in a computing environment comprising a comparator with at least one input feed; a sign selector in electronic communication with the comparator; and result flag generator in electronic communication with both the sign selector and the comparator. The sign selector has input data feeds and an equivalent number of dedicated indicators for identifying signed numbers from unsigned numbers for each of the input data feeds. The result flag generator receives a first resultant feed from the comparator and a second resultant feed from the sign selector. The sign selector can be designed to provide a resultant output. The resultant output is generated after collective operations have been performed on the input feeds and selectively on other feeds such as a sign feed and an Ini feed.
