Sound synthesis employed in many multimedia systems is a useful method to generate sounds of musical instruments. In this paper, we propose a new VLSI architecture suitable for a scalable sound synthesizer based on a programmable data-flow. The sound quality and the level of polyphony can be enhanced only by increasing operating speed and enlarging memory. A fully integrated sound synthesis system...
This paper describes the design of a 1.25 Gb/s laser diode (LD) driver with APC (Automatic Power Control) for PON (Passive Optical Network) system fabricated in a 0.18 ??m CMOS single-poly-six-metal technology. The measured -3 dB frequency bandwidth is 2.49 GHz and small signal gain is 17 dB, suitable for the operation even up to 2.5 Gb/s. The implemented laser diode driver consisted of a modulation...
This paper presents a scalable sound synthesis system and the implementation results of its prototype design. Based on the inherent data flows of sound synthesis, the proposed sound synthesizer operates according to the reconfigurable algorithm description. A fully-integrated synthesizer system is implemented based on the proposed architecture, and fabricated in a 0.18-mum CMOS process, occupying...
