FLASH-Burner

Market Survey

Why FLASH-Burner Storage Capacity

The storage capacity for DVD is typically 4.7GB The storage capacity for USB Flash drive is now in the

range of hundreds of GB Resistive

USB Drives are highly resistant to scratches DVD on the other hand are highly prone to scratches

which causes data corruption and hence its loss Access Speed

Flash doesn't have any mechanical part involved in it. Hence data reading and writing happens at a much faster rate

DVD on the other hand has a mechanical rotar associated with it. So read and write speed mainly limited by Rotor speed

Market Survey

Why FLASH-Burner .....Contd Power

The power consumption in USB drive is very less The power Consumption in DVD drive is much more

than the USB drive Portability

The size of USB drive is very small and as a result the portability is high.

The size of DVD on the other hand is much more and that makes it uncomfortable for us to carry.

Market Survey

Why FLASH-Burner .....Contd Because of the above facts the DVD drives and

hence DVDs are becoming obsolete and ultimately replaced by USB.

We will be left with no DVD drives but lot of data in DVD Disks.

Hence we are launching the Flash-Burner which transfers data from DVD to USB Flash without the need for interfacing with PC.

USB (Universal Serial Bus)

USB is an industry standard that defines the cables, connectors and protocols used for connection, communication and power supply between computers and electronic devices

USB was designed to standardize the connection of computer peripherals

Version History : USB 1.0

1.5 Mbit/s (Low-Bandwidth) 12 Mbit/s (Full-Bandwidth)

USB 2.0 480 Mbit/s (60 MB/s)

USB 3.0 5.0 Gbit/s

Optical Drive

Optical Drive(Only Reader Required) Optical Drive is primarily used in

CD Drives DVD Drives BLUE RAY Drive

File Systems Universal Disk Format (UDF)

Open vendor-neutral file system for computer data storage for a broad range of media.

It has been most widely used for DVDs and newer optical disc formats.

Other File systems to support: ISO 9660, also referred to as CDFS A file system standard published by ISO for optical

disc media Serial Communication(SATA)

Data Rates of Optical Drive

The data reading for optical disk is different for CD, DVD and Blue Ray.

CD has a low data reading rate and Blue Ray(BR) has the highest.

For each of the above devices a base data transfer rate denoted as 1x is specified in the table.

Also for each of the above a maximum transfer rate is specified in terms of maximum multiplying factor of the base transfer rate. This detail is also given in the table.

Device 1x(Mbps) Maximum Multiplier

CD 1.17 56x

DVD 10.55 20x

BR 36 12x

SATA – Optical Drive

Serial ATA (SATA or Serial Advanced Technology Attachment) Computer bus interface for connecting host bus adapters to mass

storage devices such as hard disk drives and optical drives. Advantages over the older parallel ATA (PATA) interface

Reduced cable-bulk and cost (7 conductors versus 40) Native hot swapping Faster data transfer through higher signalling rates More efficient transfer through and I/O queuing protocol.

SATA Revisions Revision 1.0(1.5 Gbit/s) Revision 2.0(3.0 Gbit/s) Revision 3.0(6.0 Gbit/s)

All Revisions are Backward compatible.

Dekcell - CPA-1095 300

Sony - DDU1621 450

Toshiba - SD-M1912 350

Since we are going to sell primarily in Indian Market, we look at low price as well as reliability.Hence we went for ACER Optical Drive

Optical Drive Controller Features

Optical Drive Controller-ODC

Highly User Programmable Both for standard and Custom Application Performs all buffer management and arbitration associated with

the data transfer Advanced data mapping operation mapping during data transfer.

This Simplifies Cache Management Tasks Intelligent Peripheral to a Micro Controller Minimal Rotational Latency for Read Operation A dedicated interface to an external error processor permits the

ODC to cope with the high error rates associated with the optical media

This Block is present inside the Optical Disk Drive itself. Only SCSI interface to be provided to the control block No need for separate cost estimation for the ODC

Design : Microcontroller forOff the Shelf Chip Approach

We will go for MSP430 microcontroller which is produced by Texas Instruments

There is a lot of flexibility in choosing the Microcontroller which acts as a bridge between the Optical Drive SATA controller and the USB controller.

The Choice we made for the microcontroller is the MSP430-F-5513 which has LCD Controlling ability.

Due to its low power modes it can be used when the device is running on battery also.

The Cost per unit of this Chip when purchased in bulk is about ₹225 to ₹250.

Design : SoC Approachusing ARM IP core

ARM Based MicroController

ARM Based Microcontroller for SoC approach.ARM9TDMI based cores to be used

Key improvements over ARM7 cores Decreased heat production and lower overheating risk. Clock frequency improvements. Shifting from a three stage

pipeline to a five stage one lets the clock speed be approximately doubled, on the same silicon fabrication process.

Cycle count improvements. 30% fewer cycles to execute on ARM9 cores as compared

to ARM7 cores. Key improvements include Faster loads and stores Exposing pipeline interlocks

The Microcontroller acts as a bridge between the Optical Drive Controller and the USB Controller

ARM9 Based Microcontroller ARM968E-S(approx cost 400 per unit)

Smallest footprint ARM9 processor with DSP enhancements, for low power, data intensive, embedded real-time applications

The smallest and lowest power ARM9 processor is ideal for many real time type applications. The processor operates efficiently from the Tightly Coupled Memory that can easily be integrated through standard interfaces.

ARM946E-S DSP enhanced cached processor with an MPU for real-time

applications running an RTOS A real time orientated processor with optional caches interfaces

plus a full Memory Protection Unit. ARM926EJ-S

Application processor with Java acceleration, DSP extensions and an MMU, for OS based applications

We go for ARM968E-S as it is best suited for our purpose

USB Interface Controller

USB Interface Controller is a host serial interface, as seen on a typical PC environment that ensures a standard, low- cost connection for peripheral devices such as USB Device storage devices, keyboards,mouse, etc

It has the following functions The USB Host Controller allocates the USB bandwidth to

attached devices through a token based protocol It enables full- and low-speed data exchange with USB

devices attached to the bus The bus supports hot plugging, un-plugging, and dynamic

configuration of the devices All transactions are initiated by the host controller

It should support all USB transfer types: Control, Bulk, interrupt and Isochronous.
