Mwave MDSP2780 DSP System-On-A-Chip

MDSP2780
DSP System-On-A-Chip

"The MDSP2780 is the most feature-rich multifunction DSP available for multimedia. It is the only programmable DSP on the market with integral Sound Blaster support and sophisticated modem and communications functionality - features that will command the attention of both sound board makers and modem vendors. IBM is serious about being a force in the multimedia chip marketplace."

Will Strauss
President, Forward Concepts

MDSP2780 is a new digital signal process for the Mwave family of products that, for the first time in the industry, incorporates the entire DSP logic subsystem on a single chip.

New on-chip features include a full suite of multimedia interfaces, high speed analog and digital communication support, extended audio and voice CODEC ports, hardware-level support for industry standard games, including Sound BlasterÖ applications, and a 32 voice wave table synthesizer.

The MDSP2780 fits seamlessly into all Mwave software products and development tools to fully exploit the audio, fax/modem, voice and images capabilities of the Mwave system.

The Mwave DSP

16-bit fixed point engine
High performance MDSP2000 series, 3-phase pipeline core delivering up to 99 MOPS (million operations per second)
Three different fixed operating speeds (17, 20, and 25 MIPS) provided by on-board PLLs
With an external oscillator source, operates at any frequency from 17 MIPS up to 33 MIPS
Addresses up to 32K of off-chip data and program store

Power dissipation:
Nominal Operation - 120mA
Peak Operation - 200 mA
Suspend - 5mA
Sleep as low as 20 mA

240-pin plastic flat pack (PFP)

The MDSP2780 Advantage - The Value of Integration

Significantly reduces board space
Less components = less cost
Shared resources on chip = lower cost
Best in class power management
Provides OEM's the opportunity to differentiate their products
Maximum flexibility for implementing jumperless designs
