FineArch Inc. has developed and manufactured on a trial basis the LSI FS-500 (FA3121037) sound decoder with a low running clock frequency and on-chip memory using Ogg Vorbis, a next-generation sound compression format that is license-royalty free with high-fidelity and a high compression rate.

According to the company, they have devoted particular attention to Ogg Vorbis as an optimal sound compression technology for embedded system devices from its earliest developmental stages. The new FS-500 was developed and manufactured as a trial product to verify the processing performance of this System IP working as an actual chip. The special feature of this System IP, said FineArch, is that through reevaluation of the hardware and firmware architecture, we have realized a low-clock rate, high-efficiency and low-memory running, while mounting the Ogg Vorbis Playing Process as software.

Since the FS-500 is equipped with a 32bit RISC CPU, it can be used as a main controller for embedded system devices. It also has a host interface that can be used as a sub-microcontroller that is dedicated to sound-processing under the control of a host controller. In addition, it can play multiple Ogg Vorbis sound sources simultaneously. It can output to individual speakers with such sound effects as equalizing, echo, panning and phase-shift stereophonic sound images (Virtual 3D) by taking advantage of the low-clock/high-efficiency running feature. The FS-500 is also compatible with MP3 and other sound formats. Compatible formats will be extended through appropriate updating of the internal CPU/DSP firmware.

The FS-500 will be completed and released this year after optimizing the firmware for portable music players, as well as minimizing its size.
