A determinant computing circuit in floating pointformat has been designed and tested for use in a CMOS ASICacoustic localization processor. The Internal Division Method(IDM) was used to implement the operation, employing amodified SRT radix-4 circuit for division operations. The unit wasdesigned for VLSI implementation in a commercial 130nm lowpowerCMOS process, with an operation frequency of 100MHz.The algorithm employed is parallelizable for future prototypes,should a higher operation frequency be required.
