Decimal-Binary Conversions in CORDIC

摘要: A special-purpose, binary computer called CORDIC (COordinate Rotation DIgital Computer) contains a unique arithmetic unit composed of three shift registers, adder-subtractors, and suitable interconnections for efficiently performing calculations involving trigonometric functions. technique is formulated using the to convert between angles expressed in degrees minutes 8, 4, 2, 1 code fractions half revolution. Decimal-to-binary conversion accomplished through generation an intermediate which variable values are +1 -1. Each these variables controls addition or subtraction particular constant formation accumulated sum represents angle. Examples presented illustrate technique. Binary-to-decimal by applying essentially same steps reverse order, but this feature not discussed fully. Fundamental principles technique, rather than details implementation, emphasized. The sufficiently general be applied decimal-binary problems other mixed radix systems decimal codes.
