Abstract :
A versatile signal processor has been designed that can perform multiple rotations, multiplications and additions within one clock cycle. The computational elements of this processor include four pipelined CORDIC rotators, two pipelined fast multipliers and two adders. A combination of register files, SRAM, and ROM provides on chip storage for coefficients, running sums and programs. The chip architecture and its applicability to complex valued signal processing tasks are discussed
