Overview
The TMS320C54V90APGE, produced by Texas Instruments, is a high-performance Digital Signal Processor (DSP) designed to implement full-featured modem technology. This DSP is intended for use in embedded systems and similar applications. It integrates a complete modem solution using just two chips: the TMS320C54V90 DSP itself, which includes on-chip RAM and ROM, and the Si3016 line-side DAA (Data Access Arrangement). The modem can connect to a host system either serially via RS-232 functionality or as an 8-bit peripheral to the processor in the host system. The TMS320C54V90 utilizes standard DSP architecture and proprietary firmware to handle modem signal processing, V.42/V.42bis compression, and AT command interpretation for modem control functions.
