The VGA example generates a 320x240 diffusion-limited-aggregation (DLA) on Altera DE2 board. A DLA is a clump formed by sticky particles adhering to an existing structure. In this design, we start with one pixel at the center of the screen and allow a random walker to bounce around the screen until ...

A general technique for the recovery of signicant
image features is presented. The technique is based on
the mean shift algorithm, a simple nonparametric pro-
cedure for estimating density gradients. Drawbacks of
the current methods (including robust clustering) are
avoided. Feature space of any nat ...

VHDL/FPGA/Verilog DDR SDRAM控制器的VHDL源代码
DDR SDRAM控制器的VHDL源代码,含详细设计文档。
The DDR, DCM, and SelectI/O&#8482 features in the Virtex&#8482 -II architecture make it the perfect
choice for implementing a controller of a Double Data Rate (DDR) SDRAM. The Digital Clock
Manager (DCM) provides the required Delay Locked Loop (DLL), Dig ...
