CF Cordic: Overview Details Name: cf_cordic Created: 31-Dec-2002 15:01:59 Updated: 08-May-2008 08:27:45 CVS: no files in cvs Other project properties Category :: Arithmetic core Development status :: Production/Stable Project maintainers Tom Hawkins Statistics view Description Cores are generated from Confluence; a modern logic design language. Confluence is a simple, yet highly expressive language that compiles into Verilog, VHDL, and C. See www.confluent.org for more info. Cordics (COordinate Rotation DIgital Computers) perform arbitrary phase rotations of complex vectors and are often used to calculate trigonometric functions and vector magnitudes. Features Each file is stand-alone and represents a specific configuration. The 4 parameters are: Rotation or Vector Mode Vector Precision Angle Precision Number of Cordic Stages All designs are pipelined with a synchronous enable and reset. The pipeline latency equals 2 clock cycles plus the number of cordic stages. The configuration parameters are coded in the file names: cf_cordic_r_32_16_12.v r : Cordic Mode. 'r' = Rotation, 'v' = Vectoring 32 : Precision of the individual vector components. 16 : Precision of the angle. 12 : Number of cordic stages. Current configurations: cf_cordic_r_8_8_8 cf_cordic_v_8_8_8 cf_cordic_r_16_16_16 cf_cordic_v_16_16_16 cf_cordic_r_18_18_18 cf_cordic_v_18_18_18 cf_cordic_r_32_32_32 cf_cordic_v_32_32_32
