COORDINATE ROTATION DIGITAL COMPUTER USING DIRECT MEMORY ACCESS ENGINES

Abstract: a device includes a coordinate rotation digital computer (cordic), a memory, a first direct memory access (dma) engine, and a second dma engine. the memory stores an array of calculation data sets and an array of result data sets corresponding to the calculation data sets. the first dma engine copies each data set of the array of calculation data sets from the memory to the cordic. the second dma engine copies each result data set of the array of result data sets from the cordic to the memory and generates a trigger in response to copying a final result data set of the array of result data sets to the memory.
