Signal Processor (ASP) Description
The ARCOFI signal processor (ASP) has been conceived to perform all CCITT and ETSI
(NET33) recommended filtering in transmit and receive paths and is therefore fully
compatible to the G.714 CCITT and ETSI (NET33) specifications. The data processed
by the ASP is provided in the transmit direction by an oversampling A/D-converter
situated in the analog front end (AFE). Once processed, the speech signal is converted
into an 8 bit A-law or
-law PCM-format or remains as a 16-bit linear word (2s
complement) if the compander is by-passed. The by-passing of the companding
depends on the bit setting in the configuration register DFICR (VDM-bits).
In the receive direction, the incoming PCM-stream is expanded into a linear format (if the
linear mode is selected, the expansion logic is by-passed) and subsequently processed
until it is passed to the oversampling D/A-converter.
Additionally to these standard codec functions, the ARCOFI provides a universal tone
generation unit and a high quality speakerphone function.
