利用java實現文件的AES加密功能
This Java AES Crypt package contains the Java class es.vocali.util.AESCrypt, which provides file encryption and decryption using aescrypt file format.
Requirements
The Java AES Crypt package only works in Java 6, but can be easily adapted to Java 5 by replacing the call to NetworkInterface.getHardwareAddress() with something else.
In order to use 256 bit AES keys, you must download and install "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" from http://java.sun.com/javase/downloads/index.jsp
xyzzy is a program for the Nintendo Wii which will read a console s OTP key storage and dump out the private encryption keys to screen and to SD card. This is useful information in case your Wii ever gets bricked and you need to re-initialize the firmware.
VoyagerGX display driver for Windows CE .NET 5.XX
Silicon Motion, Inc. VoyagerGX Driver is architected from the beginning
to support variety of features and extension of Windows CE .NET, such as
DirectDraw feature, Dynamic Rotation feature, Multimon feature, SMI Multimon
Emulation feature (using single VoyagerGX chip to drive two independent
displays), WCEfA (Windows CE for Automotive) feature, and more
The concept of the Altera Nios II embedded processor implementation inside Field Programmable Gate Array [FPGA] of the CCD camera for the “Pi of the Sky” experiment is presented. The digital board of the CCD camera, its most important components, current implementation of firmware [VHDL] inside the FPGA and the role of external 8051 microcontroller is briefly described. The main goal of the presented work is to get rid of the external microcontroller and to design new system with Nios II processor built inside FPGA chip. Constraints for implementing the design into the existing camera boards are discussed. New possibilities offered by a larger FPGA for next generation of cameras are considered.
This application note describes the three methods that can be used to
program the Flash code memory of the 89C51Rx+/Rx2/66x families
of microcontrollers. It discusses in detail the operation of the
In-System Programming (ISP) capability which allows these
microcontrollers to be programmed while mounted in the end product.
These microcontrollers also have an In-Application Programming
(IAP) capability which allows them to be programmed under firmware
control of the embedded application. This capability is also described
The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for
firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The
W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the
contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary
ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4-
bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight
sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the
W78E58B allows the program memory to be programmed and read electronically. Once the code is
confirmed, the user can protect the code for security
The SL11RIDE is a low cost, high speed Universal Serial Bus RISC based Controller board. It contains a
16-bit RISC processor with built in SL11RIDE ROM to greatly reduce firmware development efforts. Its
serial flash EEPROM interface offers low cost storage for USB device configuration and customer product
specific functions. New functions can be programmed into the I2C by downloading it from a USB Host
PC. This unique architecture provides the ability to upgrade products, in the field, without changing the
peripheral hardware.
Wishbone to LPC (Low-Pin Count) Bridge, includes master and slave modules. Supports 8-bit I/O Read and Write cycles, 8-bit Memory Read/Write cycles, DMA cycles, and up to 32-bit Firmware memory read/write cycles. Serial IRQ support is also provided.
None of this has been tested (yet) with a third-party LPC Peripheral or Host.
userial is an Free project building an USB to I2C/SPI/GPIO bridge, using the Atmel AT90USB647 chip. Hardware and Software are released under an Open Source licence. It supports the following interfaces:
* USB interface (serial emulation)
* JTAG
* I2C (TWI)
* SPI
* 8 General purpose digital I/O
* 4 Analog to Digital converters (currently no firmware support)
Behavioral models are used in games and computer graphics for
realistic simulation of massive crowds. In this paper, we present a
GPU based implementation of Reynolds [1987] algorithm for simulating
flocks of birds and propose an extension to consider environment
self occlusion. We performed several experiments and
the results showed that the proposed approach runs up to three
times faster than the original algorithm when simulating high density
crowds, without compromising significantly the original crowd
behavior.
