www.surf-com.comBuying Boards or ChipsBuying Boards or Chips

Why Boards?

Pre-requisite: Standard form factor or

Standard mezzanine-card connector

Lowest risk

Lowest initial investment

Cheapest solution in the long run Negotiation

Change vendor

Easiest migration path to next generation DSPs

Why Chips?

Proprietary form factor

Single-DSP solutions

Very high volumes (10K+)

Prediction:

By 2008 all new Tier-I infrastructure solutions will be based on standard boards and modules that are made by third parties.

www.surf-com.comWhy Put Audio & Video on the Same Chip/Module?Why Put Audio & Video on the Same Chip/Module?

Easy migration path from 0% video / 100% audio to 100% video / 0% audio and anything in-between

Minimal system delay -> higher overall quality No need to separate audio from video and send each to a separate

chip/module

Easier to establish lip-sync between audio and video when packets are lost or delayed

Lower operational expenses Only need to support one chip/board

Lower integration efforts Single API for audio and video

No need for an aggregation device to combine/split audio and video




www.surf-com.comMRFP Development ChallengesMRFP Development Challenges

A typical MRFP is composed of four components:

1. Media processing DSP code

2. Host-based state machines and APIs

3. Hardware platform

4. MRFP application
