24 Channel DAS using USB 2.0

16 Digital I/P Channels.

8 Analog I/P Channels.


9/22


USB 2.0

Easy to use for end user

Single model for cabling and connectors

Electrical details isolated from end user (e.g., bus

terminations)

Self-identifying peripherals, automatic mapping of

function to driver and configuration

Dynamically attachable and reconfigurable peripherals


10/22


USB 2.0

Wide range of workloads and applications

Device bandwidths :1 kb/s ~ 400 Mb/s Supports isochronous as well as asynchronous transfer

types over the same set of wires

Supports concurrent operation of many devices (multiple

connections)

Supports up to 127 physical devices

Supports transfer of multiple data and message streamsbetween the host and devices

Allows compound devices

Lower protocol overhead, resulting in high bus utilization


11/22


USB 2.0

Isochronous bandwidth Guaranteed bandwidth and low latencies

Flexibility

Supports a wide range of packet sizes, which allows arange of device buffering options

Allows a wide range of device data rates by

accommodating packet buffer size and latencies

Flow control for buffer handling is built into the protocol


12/22


USB 2.0

Robustness Error handling/fault recovery mechanism is built into the

protocol

Dynamic insertion and removal of devices is identified in

user-perceived real-time Supports identification of faulty devices

Synergy with PC industry

Protocol is simple to implement and integrate Consistent with the PC plug-and-play architecture

Leverages existing operating system interfaces


13/22


USB 2.0

Low-cost implementation

Low-cost sub channel at 1.5 Mb/s

Optimized for integration in peripheral and host hardware

Suitable for development of low-cost peripherals

Low-cost cables and connectors

Uses commodity technologies

Upgrade path

Architecture upgradeable to support multiple USB Host

Controllers in a system
