A new CORDIC algorithm based on sign bits prediction is presented. It is an effective method for reducing arbitrary iterations of classic CORDIC to only one iteration and transforming CORDIC iterations to simple matrix multiplications. At the same time, this algorithm is implemented and experimented on based on Synchronized Data Triggering Architecture (SDTA). Experimental results show that the average speed-up of transcendental functions tested based on our CORDIC algorithm compared with mathematic library supported in gcc3.2.2 under the given Neuron microprocessor is close to 283%.
