Implementation of usb transceiver macrocell interfaceeSAT Journals
Abstract The universal serial bus (USB) transceiver macro cell interface (UTMI) is a two wire, bi-directional serial bus interface. UTMI consists of transmitting and receiving sections, in which the transmitter of the UTMI sends data to different USB devices through D+ and D- lines whereas the receiver gets data on the same lines. UTMI is one of the important functional blocks of USB controller, which can transmit and receive data to or from USB devices. There are three functional blocks present in USB controller; those are Serial Interface Engine (SIE), UTMI and Device Specific Logic (DSL). The parallel data from SIE is taken into the transmit hold register and this data is sent to transmit shift register from where the data is converted serially. This serial data is bit stuffed to perform data transitions for clock recovery and NRZI (1) encoding. Then the encoded data is sent on to the serial bus. When the data is received on the serial bus, it is decoded, bit unstuffed and is sent to receive shift register. After the shift register is full, the Data is sent to receive hold register. This presentation reveals the FPGA implementation of UTMI transmission rate providing with USB 2.0 specifications. Further UTMI has been designed by using VHDL code and simulated, synthesized and programmed to the targeted Spartan family of FPGA in the Xilinx environment.

Solid State Drives - Seminar Report for Semester 6 Computer Engineering - VIT...ravipbhat
This report is intended as a guide to emerging solid state storage technology, in particular, to the introduction of solid state drives.
Adding a solid-state drive (SSD) to your computer is simply the best upgrade at your disposal, capable of speeding up your computer in ways you hadn't thought possible. But as with any new technology, there's plenty to learn.
The consumer is no longer limited to just accepting pre-configured systems and, even when purchasing a system, should have an avenue to understand what purpose the storage device within serves as well as how it does what it does.
A solid-state drive (SSD) is a data storage device for your computer.
In everyday use, it provides the same functionality as a traditional hard disk drive (HDD)—the standard for computer storage for many years.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. INTRODUCTION
A USB drive is a data storage device that
includes flash memory with an integrated
Universal Serial Bus (USB) interface
USB flash drives use the USB mass storage
standard, supported natively by modern
operating systems such as linux, Mac OS X,
Windows, and other Unix-like systems, as well
as many BIOS boot ROMs
4. USB drives with USB 2.0 support can store more data and
transfer faster than much larger optical disc drives like
CD-RW or DVD-RW drives.
They are smaller, faster, have thousands of times more
capacity, and are more durable and reliable because they
have no moving parts
The term drive persists because computers read and
write flash drive data using the same system commands
as for a mechanical disk drive.
5. A Kingston card reader which accepts
Micro SD memory cards (Transcend card
shown inserted) and acts as a USB flash
drive, resulting in a size of approximately
2 cm in length, 1 cm in width and 2 mm in
thickness
Punched cards in storage at a U.S. Federal
records center in 1959. All the data visible
here would fit on a 4 GB flash drive
6. STRUCTURE OF PEN DRIVE
A flash drive consists of a
Printed circuit board
USB connector
Type-A USB connection
Drives for other interfaces.
7. TECHNOLOGY USED
Flash memory combines a number of older technologies
The memory storage was based on earlier EPROM and
EEPROM technologies.
Hardware designers later developed EEPROMs with the
erasure region broken up into smaller "fields" that could be
erased individually without affecting the others.
The development of high-speed serial data interfaces such as
USB and the simultaneous development of small, high-speed,
low-power microprocessor systems allowed this to be
incorporated into extremely compact systems.
8. Design and implementation
Internals of a typical USB
flash drive
• 1 USB Standard-A plug
• 2 USB mass storage
controller device
• 3 Test points
• 4 Flash memory chip
• 5 Crystal oscillator
• 6 LED
• 7 Write-protect switch
(Optional)
• 8 Space for second flash
memory chip
9. Essential components
There are typically four parts to a flash drive:
Standard-A USB plug – provides a physical
interface to the host computer.
USB mass storage controller – a small
microcontroller with a small amount of on-chip
ROM and RAM.
NAND flash memory chip(s) – stores data (NAND
flash is typically also used in digital cameras).
Crystal oscillator – produces the device's main
12 MHz clock signal and controls the device's
data output through a phase-locked loop.
10. The typical device may also include:
Jumpers
LEDs
Write-protect switches
Unpopulated space
USB connector cover or cap
Transport aid.
Some drives offer expandable storage via an internal
memory card slot, much like a memory card reader.[
11. LETS EXPLORE :-
USB Flash Drives or commonly called as Pen Drives are
popular removable storage media having a storage capacity
from 64 MB to 32 GB. They are preferred over the other conventional
storage devices like floppy disks or CD ROMs as they are faster
, smaller and have a longer life span.
12. INTERNAL STRUCTURE
1.A printed circuit board carrying the circuit elements and a USB
connector is shown in the above image.
2.The USB connector is protected by either retracting into the
body or by covering by a removable lid. There are two chips,
one is the USB controller and the other is the flash memory chip
13. CONTROLLER
The IC SK6211 shown in the above image is a controller which facilitates the data
communication between the PC/Laptop and the flash memory (EEPROM) of the
pen drive.
It is fully compatible with USB 2.0 protocols and USB Mass storage class V1.0
specification.
The devices like memory card, hard disk, pen drive etc with high data storage
capacity fall under the category of Mass Storage Devices.
14. .
MEMORYCHIP1
The chip which is shown in the image above is a NAND type flash memory which has
fast read, write and erase cycles. The data is stored in memory cells of the EEPROM.
The storage capacity of this memory is 2GB. There is another similar chip with
storage capacity of 2GB on the other side of the PCB, thereby making the total
capacity of the pen drive to be 4GB.
15. MEMORY CHIP
The above image shows the other side of PCB. The second memory
chip, a crystal oscillator and a number of surface mount
components are soldered which are required for the operation of
the pen drive.
16. OSCILLATOR
The crystal oscillator produces the clock signal for the
correct operation of the device. The crystal oscillator
used here runs at a clock frequency at 12 MHz.
17. COMPARISON WITHTape
Magnetic Tapes stores data sequentially, hence sequential accessing of data is
possible only, whereas in USB flash drive random accessing can be done.
Floppy disk
Size of pen-drive is much smaller than floppy Disk(3.5 inch).
Not used in modern computers.
Optical media
RW varieties up to about 1,000 erase/write cycles,
while modern NAND-based flash drives often last for
500,000 or more erase/write cycles.
They are slower than their flash-based counterparts
Standard 12 cm optical discs are larger than flash drives and more subject
to damage.
18. ADVANTAGES
Flash drives use little power, have no fragile
moving parts, and for most capacities are small and
light.
Data stored on flash drives is impervious to
mechanical shock, magnetic fields, scratches and
dust.
Specially manufactured flash drives are available
that have a tough rubber or metal casing designed to
be waterproof and virtually "unbreakable". These
flash drives retain their memory after being
submerged in water, and even through a machine
wash.
19. DISADVANTAGES
Flash drives can sustain only a limited number of
write and erase cycles before the drive fails.
USB flash drives are more expensive per unit of
storage than large hard drives, but are less expensive
in capacities of a few tens of gigabytes as of 2011.
