Overview
The TMS320C54V90AGGU is a high-performance digital signal processor (DSP) manufactured by Texas Instruments. It is designed to implement full-featured, high-performance modem technology, particularly for use in embedded systems and similar applications. This DSP integrates a complete modem solution using only two chips: the TMS320C54V90 DSP itself 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 a standard DSP architecture and proprietary firmware to perform all modem signal processing, including V.42/V.42bis compression and AT commands interpretation for modem control functions.
