ST7529液晶驅(qū)動(dòng) The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver Circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains
power supply Circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

A PLD Based Delta-Sigma DAC
Delta-Sigma modulation is the simple, yet powerful,
technique responsible for the extraordinary
performance and low cost of today s audio CD
players. The simplest Delta-Sigma DAC consists of a
Delta-Sigma modulator and a one bit DAC. Since,
both of these components can be realized using
digital Circuits, it is possible to implement a low
precision Delta-Sigma DAC using a PLD.
ST7787 芯片的SPEC，比亞迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and
320 gate line driving Circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial
Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display
data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to
minimize power consumption. In addition, because of the integrated power supply Circuits necessary to drive liquid crystal,
it is possible to make a display system with the fewest components.

These are P-Channel enhancement mode silicon gate
power fi eld effect transistors. They are advanced power
MOSFETs designed, tested, and guaranteed to withstand a
specifi ed level of energy in the breakdown avalanche mode
of operation. All of these power MOSFETs are designed for
applications such as switching regulators, switching
converters, motor drivers, relay drivers and drivers for other
high-power switching devices. The high input impedance
allows these types to be operated directly from integrated
Circuits.

This design contains four top level Circuits: sv_chip0.vhd, sv_chip1.vhd, sv_chip2.vhd and
sv_chip3.vhd each of them built by one Virtex2000E fpga chip. This design is hierarchical and the
sub-Circuits can be used as smaller benchmarks.
VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.
The implementation is in library-like form All needed components up to, including the round/key schedule Circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.
this is a document about radio frequency identification RFID, this was a project ,i have done last year ,actually this technology is a very inpotrtant one due to its relation with newest technologies , like GPS , or the miniturization of integrated Circuits ,and that is described in chapter 3 . chapter 1 gives an introduction of the technology RFID , chapter 2 gives a discussion of a library using RFID , and chapter 3 is about the future of RFID , and finally the conclusion .
