ΓòÉΓòÉΓòÉ 6. Mwave Concepts Overview ΓòÉΓòÉΓòÉ

Select the following headings for information about specific aspects of the
Mwave adapter and software:

o Understanding Functions Provided by Mwave

o Understanding the Mwave Hardware Platform

o Understanding Mwave System Software

o Understanding Mwave Device Drivers

o Understanding Dynamic Resource Allocation


ΓòÉΓòÉΓòÉ 6.1. Understanding the Functions Provided by Mwave ΓòÉΓòÉΓòÉ

The Mwave adapter and software provide the following functions:

o Sound Blaster** compatible emulation for games
o Modem data transfer at rates of 2400 bps, 14 400 bps, and 28 800 bps using
  the Mwave Modem
o Modem fax transfer at 14 400 bps using the Mwave Modem
o Software configuration of hardware settings using the Mwave Hardware
  Configuration Utility


ΓòÉΓòÉΓòÉ 6.2. Understanding the Mwave Hardware Platform ΓòÉΓòÉΓòÉ

The Mwave hardware platform features a DSP specifically designed to meet the
demands of multimedia processing.  An Mwave DSP can integrate on one chip many
of the on-board peripherals required for multimedia application.  Instead of
requiring separate cards or physical devices to provide multimedia functions
such as fax modem, data modem, games support and audio support, the Mwave DSP
(in conjunction with the Mwave software) can provide all these functions on a
single adapter card.


ΓòÉΓòÉΓòÉ 6.3. Understanding Mwave Software ΓòÉΓòÉΓòÉ

Mwave software consists of device drivers for Microsoft** Windows, Operating
System/2* (OS/2*) Warp, and DOS, and software.  The system software consists of
an Mwave manager that runs on the PC and a real-time, multitasking Mwave
operating system and virtual hardware tasks that run on the DSP and peripheral
hardware. These interfaces make the multimedia capabilities of any PC with an
Mwave adapter and software appear merely as extensions to Windows, OS/2 Warp,
or DOS.


ΓòÉΓòÉΓòÉ 6.4. Understanding Mwave Device Drivers ΓòÉΓòÉΓòÉ

Mwave device drivers are MCI-compliant device drivers that provide the software
interface between the application programs running on the PC and the Mwave
manager, enabling a single Mwave application to run on a variety of Mwave
platforms.  The Mwave device drivers include the:

o Mwave audio device driver
o Mwave telephony devices drivers including modem, FAX and TAM device drivers
o Mwave games device driver

Application programs call an Mwave device driver when they want to access the
multimedia functions provided by that device driver.  For example, a fax
application calls the FAX device driver when it wants to send or receive a fax.
The device driver then sends a message to the Mwave manager, which loads the
DSP tasks function requested.  The Mwave/OS then schedules when each task can
run on the DSP.  The task runs and the function is provided to the application
program.

When more than one device driver wants to load and run DSP tasks at the same
time, the Mwave/OS schedules the tasks based on the priority assigned to the
driver by the DRA facility.  For more information, read Understanding Dynamic
Resource Allocation.


ΓòÉΓòÉΓòÉ 6.4.1. Mwave Audio Device Driver ΓòÉΓòÉΓòÉ

The Mwave audio device driver provides the following services:

o Waveform audio services provide recording and playback of PCM waveform audio
  data.

o MIDI audio services provide support for playback of MIDI data through the
  Mwave internal synthesizer.

o Auxiliary audio device services provide playback of compact disk audio from a
  CD-ROM disc drive.


ΓòÉΓòÉΓòÉ 6.4.2. Mwave Telephony Device Drivers ΓòÉΓòÉΓòÉ

The Mwave telephony device drivers include:

o FAX device driver that provides fax send and receive functions and controls
  the Mwave fax modem.

o TAM device drivers for Phone Line and Message.  The Phone Line device driver
  controls all operations that involve the telephone line, such as making a
  call, answering a call, and remotely reviewing or recording a message.  The
  Message device driver controls the local review and recording of messages.

o Modem device driver that provides modem function that enables you to send and
  receive data or fax information at transfer rates or 2400 bps, 14 400 bps, or
  28 000 bps.  The modem device driver supports Hayes** AT and S-register
  commands. (see the help for the Mwave Modem for more information.  To access
  help, double click the Mwave group, then double click the Mwave Modem icon.
  The Mwave Modem appears.  Click the Help pull-down and then click Contents.)

The FAX and modem device drivers can operate at different levels of service,
depending on how many other applications that use the DSP are running at the
same time.  These device drivers can operate at a maximum transfer rate of 28
800 bps and a minimum transfer rate of 2400 bps.  The default modem transfer
rate is set to 14 400 bps to allow rapid transfer and enable other applications
that use the DSP to run at the same time.


ΓòÉΓòÉΓòÉ 6.4.3. Mwave Games Device Drivers ΓòÉΓòÉΓòÉ

The Mwave games device driver provides support for Sound Blaster** games and
audio and allows your computer to work as if a Sound Blaster card is installed.
The Mwave games device driver provides support for:

o Sound Blaster games

o Sound Blaster Pro games

o Sound Blaster Pro games with Qsound

See Setting Mwave Games Mode for more information.


ΓòÉΓòÉΓòÉ 6.5. Understanding Dynamic Resource Allocation ΓòÉΓòÉΓòÉ

Dynamic resource allocation is a feature which reduces conflicts between device
drivers competing for DSP resources.  By assigning different priorities to the
device drivers, the Dynamic Resource Allocation (DRA) facility enables Mwave to
transparently control resource allocation and enable device drivers that would
otherwise cause conflicts to run at the same time.

Resource allocation is based on:

o the priority of the device driver entering the system and

o the amount of DSP resources that the driver requires to operate.

DSP resource consumption also corresponds to the level of service provided by
the Mwave device driver.  Higher levels of service correspond to faster or more
complex functions and generally consume more DSP resources than lower levels of
service, which correspond to slower or simpler functions.  For example, when
the Mwave Modem operates at 28 800 bps, the device driver consumes more DSP
resources than when it operates at 14 400 bps or 2400 bps.  Similarly, when the
MIDI driver provides 32 voice support, it consumes more DSP resources than when
it provides 24 or 16 voice support.

When one device driver is loaded and consuming DSP resources and another device
driver attempts to load:

 1. The DRA facility evaluates the priority of each device driver and allocates
    resources.
 2. The device driver with higher priority is allowed to operate at the level
    of service requested.
 3. The DRA facility forces the other device driver to reduce its level of
    service to accommodate the resource needs of the higher priority driver.
    In some cases, the DRA facility must force the other device driver to stop
    temporarily to free sufficient DSP resources.

For example, suppose that the high priority driver is the Mwave Modem operating
at 28 800 bps and the lower priority driver is Mwave Audio providing 24-voice
support for MIDI.  The DRA facility allows the Mwave Modem driver to operate at
28 800 bps and forces the Mwave Audio driver to reduce its support from
24-voices to 16-voices to 8-voices as necessary to free resources.  When the
Mwave Modem driver ceases to consume as many resources, the DRA facility allows
the Mwave Audio driver to dynamically increase its level of service according
to resource availability to return to 24-voice support.

ΓòÉΓòÉΓòÉ 10. Using the Mwave Modem ΓòÉΓòÉΓòÉ

Setting Mwave Modem Speed in DOS
Setting Mwave Modem Speed in OS/2 Warp

The Mwave Modem is a fax and data modem that runs in the DOS, Windows 3.1,
Win-OS/2, and OS/2* Warp operating environments.  The Mwave Modem starts
automatically when DOS, Windows, or OS/2 Warp is started.  When you open any
application that requires a fax or data modem for communication (for example,
WinFax Pro for Windows or ProComm Plus for DOS), the Mwave Modem begins to
consume DSP resources on your Mwave adapter. Therefore, when you finish using
an application that requires the Mwave Modem, you should close the application
instead of minimizing it.  This allows the Mwave Modem to free system resources
for other applications to use.


ΓòÉΓòÉΓòÉ 10.1. Setting the Mwave Modem Speed in OS/2 Warp ΓòÉΓòÉΓòÉ
