Modulo address generator circuit for digital signal processing

摘要

The modulo address generator is used in a digital signal processor to enhance the execution of algorithms. The generator has a first adder 21 that adds an increment to the actual address. A second adder 22 generates the complement of the maximum address to a minimum address to provide a cycle correction value. An adder/ subtractor 23 generates a corrected address that is fed to a multiplexer 25 controlled by a comparator 24
