1024-bit RSA encryption algorithm

Description of the RSA algorithmSelect two large prime numbers with the same length, p and q , Calculate the product:n = pqThen pick a random encryption key, make e, (p-1) (q-1) are prime numbers from each other.Finally, calculate the decryption key d use Euclid extended algorithm to meet the requ...

Realization of image median filtering FPGA

The realization of image algorithm based on FPGA, including the verification of the algorithm of MATLAB is implemented in the FPGA algorithm, using Xilinxdevelopment environment, verified by....

Histogram equalization FPGA implementation

Real-time image histogram equalization in FPGA, effective use of FPGA chip-chip resources, no need to add external memory chips. The code is based on YCbCr, actually only the luminance histogram equalization, time after which a synchronous CB,CR color components, avoiding partial color problem! Code...

Implementation of Pipeline 2D-DCT for MPEG Compression

The 2-D DCT transforms a block of N x N pixels from the spatial domain into the frequency domain. Before compression, image data in memory is divided into several blocks. Each block consists of 8x8 pixels. Fig. 2 shows that in the resulting coefficient block, the coefficient in t...

sobel edge detection

This VHDL/Verilog or C/C++ source code is intended as a design reference which illustrates how these types of functions can be implemented.  It is the user's responsibility to verify their design for consistency and functionality through the use of formal verification methods.&nb...

ADPLL behavior model

The attached files contain the behavior model of ADPLL. The 6 bits TDC is used. A fast clock is used to count the the timing difference between the input reference clock and feedback clock. The TDC resolution is higher if the fast clock is faster. The digital loop filter produces 1...

AHB transfers to APB source and APB read/write verilog code

Converts AHB peripheral transfers to APB transfersThe 16-Slot APB Bridge provides an interface between the high-speed AHB domain and the low-power APB domain. The Bridge appears as a slave on AHB, whereas on APB, it is the master. Read and write transfers on the AHB are converted into...
