An integrated DSP Solution that features HotHaus Technologies' suite of DSP telecommunciations software for the ’C2xx family is available today for North American customers via TI distribution.

The HausWare™ algorithms and DSP software framework provide all the elements required to support a wide variety of multi-tasking telecommunications applications, and shorten the learning curve for product developers using DSPs for the first time. Applications include point-of-sale terminals, remote metering and security, feature phones, multi-fax machines, and computer telephony. Through the use of a DSP API and object-oriented methodology, HausWare is changing the way developers field DSP-based products by buffering them from the underlying complexity of algorithms and multitasking.

The base package of software includes all the algorithms necessary to control multiple PSTN lines, a V.22bis modem, and an ADPCM (G.721) waveform coder. Optional additions to this base package include a V.32bis modem, and a T.30 fax protocol with associated fax modems. The HausWare Starter Kit, which includes a TMS320C203 DSP-based telephony platform and algorithms in on-board Flash, can carry developers from algorithm evaluation, through to proof of concept prototyping, and on to application development using C tools on a PC.

HausWare API

The HausWare API (HAPI) provides programmers with access to HausWare algorithms on a DSP target processor, and the Host HausWare API (HHAPI) extends this functionality to external host processors. The HausWare Starter Kit includes a PC x86 version of HHAPI that supports a serial port interface to the DSP. Developers can use Borland C++ V4.5 or Microsoft® Visual C++ V1.52 (not included) to develop Client Applications on a PC, which use HHAPI to communicate with the HausWare algorithms running on the DSP hardware.

Once the prototyping phase of development is complete, the PC C code can be recompiled for the end-product DSP. If an external host is used in the end-product, the code can be recompiled for it, since HHAPI supports a variety of other host processors. A Windows DLL and ActiveX Control version of HHAPI are also available.
