Abstract
A sine/cosine generator with coarse and fine angles having compressed sine and cosine read only memories (ROMS) by use of symmetry of coarse angles about .pi./4 and, optionally, symmetry of fine angles about 0. The output of the ROMs directly feed multiplexers for utilization of the compressed storage. Addressing of complementary coarse angles is with one's complementing of the address and of complementary fine angles is with two's commplementing of the address. Fine sines and cosines are stored in recoded version for direct use in multipliers for computations using the sum of angles formulas.
