VLSI implementation of 3D sound movement

VLSI implementation of a sound movement system is described, which is dedicated to mobile application. This system is based on low cost 3D sound localization and coefficient interpolation methods, and realizes the sound movement at all points in 3D space by means of efficient coefficient storage scheme. The proposed system is synthesized from Verilog-HDL description, which requires only 30,000 gates. Moreover, a prototype system is implemented on FPGA board and subjective tests are performed to evaluate the effectiveness of the proposed 3D sound movement.
