- To followup on myself, here's some more info on the MWave board by IBM & TI:
- (from Byte Nov 92)
- "IBM has formed an alliance with TI and Intermetrics, a software
- development company, to bring out a product called the MWave.
- IBM will first be producing a plug-in board for ISA or MCA, but
- it also has plans to produce PS/2 systems with DSP technology
- on the motherboard by mid-1993.
-
- TI engineered the DSP chip used in the MWave. The TMS320M500
- delivers 17-MIPS performance in a 16-bit data fixed-point
- package. The processor has seven lines for seiral data input
- and a bus data line (which is host-specific) and multi-channel
- DMA for all I/O. Although the chip deals with 16-bit data, the
- program memory bus is 24 bits wide. The DSP in to a board that
- includes a MIDI port, a UART (universal asynchronous receiver/
- transmitter), stereo A/D converters and telephony AIC interfaces.
-
- TI will develop an OEM distribution channel for the MWave,
- offering it to systems manufacturers for integration into their
- motherboards. At this fall's COMDEX, TI was scheduled to
- announce a DDK with sample drivers for speech, audio, and telephony.
-
- Operating-system support is provided by IBM, whose Burlington,
- Vermont, product group developed a multitasking operating system
- for the MWave project. This embedded operating system, the MWave
- DSP manager, sits on top of OS/2 or Windows and can handle
- functions like JPEG video compression, voice recognition, data
- and fax modems, echo cancellation, music, and text-to-speech
- conversion.
-
- The MWave DSP manager is a virtual device driver that provides
- a high-level API for digital signal processing in either
- environment. This API is the platform that provides a socket
- for device drivers. IBM wants to use this technology to
- increase desktop functionality - integrating the fax, telephone,
- dictation machine, and other office appliances into the PC.
-
- IBM's objective is for this product to became as pervasive
- as the math coprocessor. For this to occur, application
- development will have to proveed at a pace with the development
- of support hardware. To further this end, IBM is out to enlist
- the support of major software development houses, such as
- Microsoft, Borland, Lotus and WordPerfect."
-
- Anyone have any info on the availability or pricing for this thing ?
