摘要：A CORDIC processor has a plurality of stages, each of the stages having a Xinput, Y input, a sign input, a sign output, an X output, a Y output, a mode control input

having a ROTATE or VECTOR value, and a stage number k input, each CORDIC stagehaving a first shift generating an output by shifting the Y input k times, a second shiftgenerating an output by shifting X input k times, a multiplexer having an output coupledto the sign input when the mode control input is ROTATE and to the sign of the Y inputwhen the mode input is VECTOR, a first multiplier forming the product of the first shiftoutput and the multiplexer output, a second multiplier forming the product of thesecond shift output and an inverted the multiplexer output, a first adder forming the Xoutput from the sum of the first multiplier output and the X input, and a second adderforming the Y output from the sum of the second multiplier output and the Y input.
