Design of Constant Divider and Its BIST Implement
常数除法器的设计及其BIST实现

The constant division algorithm that has been reported by Srinivasan to suit for the special application of wide band audio decompression processing, such as MPEG audio and AC\|3,is developped. A structure of constant divider that requires only a certain set of integer divisor is given with the regular cell array as the main part of operation, so this structure is area\|effective, suitable for VLSI implementation, and easily extend its scale. At the same time, for the need of testing and practicable application, we also design the Built\|In Self\|Test circuit to make it easy to embed the whole system.
