    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.
