摘要： A memory cell system for a dynamic random access memory (DRAM) array is disclosed. In an exemplary embodiment of the invention, the system includes a plurality of data storage elements arranged in rows and columns. A plurality of wordlines corresponds to the columns, and a plurality of lower bit lines corresponds to the rows, with each of the plurality of lower bitlines further being associated with a plurality of upper, complementary bitlines thereto. The plurality of upper bitlines are vertically aligned with the plurality of lower bitlines, thereby defining a plurality of vertically folded bitline pairs. Further, a plurality of sense amplifiers are arranged in the rows, with each of said plurality of sense amplifiers having one of said plurality of vertically folded bitline pairs as inputs thereto. When one of the plurality of wordlines is activated, a subset of the rows corresponding to the vertically folded bitline pairs is activated.

摘要： The circuit library available for logic synthesis is limited to a single dynamic circuit block or logic synthesis block. The circuit design method includes first defining the logic synthesis block and then performing logic synthesis for a predetermined logical operation to be implemented. The logic synthesis step constrained to the single logic synthesis block produces an intermediate circuit design which necessarily comprises a series of dynamic circuit blocks, each associated with a single reset signal. Once the intermediate circuit is produced, the circuit design method includes eliminating unnecessary devices from the intermediate circuit to produce a final logic circuit, and then sizing the devices in the final circuit to complete the design.

摘要： High-precision floating-point function estimates are split in two instructions each: a low precision table lookup instruction and a linear interpolation instruction. Estimates of different functions can be implemented using this scheme: A separate table-lookup instruction is provided for each different function, while only a single interpolation instruction is needed, since the single interpolation instruction can perform the interpolation step for any of the functions to be estimated. Thus, significantly less overhead is incurred than would be incurred with specialized hardware, while still maintaining a uniform FPU latency, which allows for much simpler control logic.
摘要翻译：高精度浮点函数估计分为两个指令：低精度表查找指令和线性插值指令。可以使用该方案来实现不同功能的估计：为每个不同的功能提供单独的表查找指令，而仅需要单个插补指令，因为单个内插指令可以执行任何功能的内插步骤估计。因此，与专用硬件相比，产生的开销大大降低，同时仍保持统一的FPU延迟，这允许更简单的控制逻辑。

摘要： An apparatus, a method and a computer program are provided to reduce leakage current in a processor. Traditionally, extra logic is employed to reduce leakage currents. However, reducing leakage current without sacrificing fine grain operations and speed can be difficult. Achieving such a goal can be accomplished by incorporating a multiplexer (mux) into the scan-in path of scan registers so that units or sub-units of the processor can be powered down individually. Additionally, the muxes are not incorporated into time paths, so speed can be preserved.
