This project demonstrates the use of secure hash functions technique
to implement a file encryption / decryption system.
This implemented application can encrypt / decrypt multiple files
on the fly using a password. The password supplied by the user
is used as the source message from which the hash code (key) is
generated using the SHA algorithm. Then this key is used to
enctypted the data in the file(s). This key is stored in the
encrypted file along with the encrypted data.

MCPU is a minimal cpu aimed to fit into a 32 Macrocell CPLD - one of the smallest available programmable logic devices. While this CPU is not powerful enough for real world applications it has proven itself as a valuable educational tool. The source code is just a single page and easily understood. Both VHDL and Verilog versions are supplied. The package comes with assembler, emulator and extensive documentation.
The circuit is drawn for measurement of acceleration from –1000 mg until + 1000 mg. It can be placed in kantra n the car and be supplied from the sheath of electric lighter. The circuit includes one indicative LED and a screen LCD.

toolkit. Please read the bug report form for more details.
This program requires the DSP2833x header files.
//
// This program requires an external I2C RTC connected to
// the I2C bus at address 0x6f.
//
// As supplied, this project is configured for "boot to SARAM"
// operation. The 2833x Boot Mode table is shown below.
// For information on configuring the boot mode of an eZdsp,
// please refer to the documentation included with the eZdsp,
A certification path is an ordered list of certificates starting with a certificate issued by the relying
party s trust root, and ending with the target certificate that needs to be validated. Certification
path validation procedures are based on the algorithm supplied in ITU-T Recommendation X.509
and further defined in Internet Engineering Task Force (IETF) Request for Comments (RFC)
3280. Certification path processing verifies the binding between the subject distinguished name
and/or subject alternative name and the subject public key defined in the target certificate. The
binding is limited by constraints, which are specified in the certificates that comprise the path,
and inputs that are specified by the relying party. To ensure secure interoperation of PKI-enabled
applications, the path validation must be done in accordance with the X.509 and RFC 3280
specifications. This document provides the test assertions and the test cases for testing path
validation software against these specifications.
* 1. Run the Advanced Evaluation Board (AEB) Control software program
* (Start>AudioCodes IPM-260 SDK>).
* 2. Connect the Evaluation Board s E1 connector to the IPM-260 s first E1

This is the model of boost converter. The control of this converter is PID. With changing the cofficient of the P-I and D a good replay can be supplied.
The version of CodeWarrior used in the ARM Development Suite
cannot export projects in makefile format. Manually producing
makefiles from CodeWarrior projects is not an easy task. The
aim of mcp2make is to make the conversion simpler and to require
substantially less effort.
mcp2make is supplied as a free-of-charge, unsupported utility.
