Abstract: The elements of a transform processing circuit are switchable to change the order of data in a data stream and/or to perform a fast Fourier transform (FFT) or inverse fast Fourier transform (IFFT) on the data stream. Each arithmetic circuit element performs an M-point butterfly operation on complex sample points and includes an adder/subtractor and a serial memory capable of storing M/2 sample points. Each multiplication unit performs an n-point complex twiddle factor operation on its input. The conjugator units conjugate inputted sample points. All circuit elements are connected to buses by switches. These connections are switchable so that in one switch state data input at left terminal flows to right terminal and in another state data input at right terminal flows to left terminal. The state of the bus switches also determines whether the circuit performs a FFT, an IFFT, or a bit reversal operation on input data. Transfer processing circuit may be incorporated into an integrated circuit together with a complex multiplier and a multiplexer, the integrated circuit is capable of performing FFT and IFFT operations on vectors or on transformed vectors and is capable of performing vector multiplication.

Abstract: A diesel engine (10) has an NOx and/or COx exhaust gas (12) storage catalytic converter (18) which is regenerated by exposure to a supply of reduction agent. The reduction agent is supplied as an increased mass flow with the exhaust gas, either by a supplementary injection of fuel into the diesel engine (10) or into the exhaust system (12). An Independent claim is also included for an apparatus for the above process. Preferred Features: The supplementary injection during the regeneration is alternately activated and de-activated. The variation in fuel supply is regulated to optimize the match between burning fuel and the available oxygen. The regeneration is sub-divided into active and inactive phases, suppressing the formation of strong odors and undesirable gases especially hydrogen sulfide and ammonia. The duration of the active and/or inactive phases is regulated preferably in accordance with the sulfur load, a current lambda value, the catalyst temperature, or a defined motor operating condition. With progressive increase in the required regeneration duration, the active and/or inactive phases are progressively shortened. The volume of supplementary fuel injected during the active phases is varied according to engine load, current lambda value, catalyst temperature, or a defined motor operating parameter, and is reduced with increasing regeneration duration period.
