Abstract:
A static random access memory (SRAM) device includes a memory array of a plurality of memory cells, a controller that receives an external clock signal formed by a succession of external pulses and generates an internal clock signal formed by a succession of internal pulses, and a driving circuit that receives the internal clock signal. The controller is operable in a first mode, wherein the controller generates, for each external pulse, a corresponding internal pulse and the controller controls the driving circuit so that the driving circuitry carries out one access to the memory array for each internal pulse. The controller is further operable in a second mode, wherein the controller generates, for each external pulse, a pair of internal pulses, and the controller controls the driving circuitry so that, for each pair of internal pulses, the driving circuitry writes a first data item in a set of memory cells, and then reads the set of memory cells, so as to acquire a second data item.
Abstract:
A method and system for reducing power consumption in digital circuits using charge redistribution, comprising a plurality of signal lines, an intermediate floating virtual source/sink, and a charge redistribution circuit connected to each said signal line that isolates said line from its source and connects it to the intermediate floating virtual source/sink during an idle period prior to a change of state. This charge redistribution provides steady state statistical independent advantage due to charge recycling without inserting extra complimentary line.
Abstract:
A linear scalable method computes a Fast Fourier Transform (FFT) or Inverse Fast Fourier transform (IFFT) in a multiprocessing system using a decimation in time approach. Linear scalability means, as the number of processor increases by a factor P (for example), the computational cycle reduces by exactly the same factor P. The method includes computing the first two stages of an N-point FFT/IFFT as a single radix-4 butterfly computation operation while implementing the remaining (log2Nnull2) stages as radix-2 operations. Each radix-2 operation employs a single radix-2 butterfly computation loop without employing nested loops. The method also includes distributing the computation of the butterflies in each sage such that each processor computes an equal number of complete butterfly calculations thereby eliminating data interdependency in the stage.

Abstract:
A voltage level translator for digital logic circuits provides high level to low level voltage translation with equal rise and fall delays. The voltage level translator may include an input high voltage logic inverter (operating at the high voltage level) and connected to an output low voltage logic inverter operating at the low voltage level via a voltage reduction circuit. A related method for providing high level to low voltage translation may include providing an input inverter operating at the high voltage level and an output inverter operating at the low voltage level. Furthermore, the output of the high voltage inverter may be coupled to the input of the low voltage inverter after reducing the output voltage of the high voltage inverter to the required level.

Abstract:
A capacitor discharge ignition (CDI) system is capable of generating intense continuous electrical discharge at a spark gap for a desired duration and may include a second controllable power switching circuit with its input terminal connected to an output terminal of a high voltage DC source device. An output terminal of the second controllable power switching circuit is connected to an input terminal of a first power switching circuit. The second controllable power switching circuit may also have a control terminal connected to an output of a controller. The first controllable power switching circuit may be used for discharging a discharge capacitor, and the second controllable power switching circuit may cause charging of the discharge capacitor. As such, an ignition current through an ignition coil of the system is enabled for any desired number of cycles during both the charge and discharge cycles of the discharge capacitor.
