SGS-THOMSON ST18932
EMU/PC
with very rare 1991 prototype DSP ASIC chip v0.8
vintage ISA platform development card
with 62 chips in sockets
one of which is the ST18932 v0.8 chip
and several CY7C128A and CY7C185 and CY7C199 chips
The application-specific ST18932 digital-signal-processor core from SGS-Thomson Microelectronics allows designers to customize the complete chip from megacell and standard-cell libraries on commercially available workstations like those from Mentor Graphics. The 18932 is the first software-programmable DSP megacell for a customer-designed ASIC device, the company claims. The 18932 for the first time extends customer-designed DSP chips to applications in low-bit-rate, digitized voice communications. Consequently, it can handle functions that include high-quality speech encoding, multipath channel equalization, and decoding.
As well, this chip is the basis for the DSP chip on Sound Blaster cards:
Creative Technology SB16's ASP is an digital signal processor based ASIC from SGS-Thomsons ST18932. This design consists of five memory elements- four 512 words x 8bits program RAMs, a 512x16 data RAM -plus the DSP megacell. Power consumtion is 350mW and 0.5mW standby. The 13 MIPS application specific DSP core has been used for data compression techniques. The customized algorithm implemented in th ST18932 assembler language succeded in saving 75% of equivalent disk space over competitors' solution then decoding a full 16-bit stereo recording. Development time was five months, from concept to finished prototypes. ...'"
