Abstract
PURPOSE:To realize multi-dimensional arithmetic processing with no waste and at a high speed by securing such constitution where the 2-dimensional data can be produced with a switching operation carried out between X and Y addresses and the lambda axis data on each 2-dimensional data area in taken out for production of the 3-dimensional data just with addition of a prescribed value to the X address. CONSTITUTION:In an address generating circuit 16, a mode switch part 163 receives a command from a host CPU 11 and sends a switch signal to an address switch part 164 when fast Fourier transformation processing FFT is started for 1-dimension (X), 2-dimension (Y) and 3-dimension waveforms. Then the X and Y addresses are outputted as they are to the part 164 at the 1-dimensional FFT processing. The X and Y addresses are replaced with each other and outputted to the part 164 at 2-dimensional FFT conversion processing. At the 3-dimensional FFT conversion processing, the Y address is outputted as it is to the part 164 and at the same time the X address is sent to an adder 165 for production of an address (X+DELTAx). This address (X+DELTAx) is sent to a register 166. Thus it is possible to realize the multi-dimensional arithmetic processing with no waste and at a high speed.
