VECTOR OPERATION CORE AND VECTOR PROCESSOR

A vector operation core and a vector processor are provided. The vector operation core use two three-input adders and four data negators, so that the data input into the input adders may be flexibly negated. In addition to being provided with the vector operation core, the vector processor also comprises a control unit, which controls a selector and the negators in the vector operation core. The vector processor may simultaneously support butterfly operations in a base 2, base 3 and base 5 fast Fourier transform. The vector operation core may be widely applied to the design of the a programmable vector processor in a multimode-compatible mobile terminal chip.
