המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory Dynamic Hardware Accelerators is a new term that we came up with in order to state the process of changing the same specific hardware's logic for a period of time in order to accelerate different functions. The goal is to accelerate a regular software code on the Linux OS by using the dynamic hardware accelerators approach using a separated to software & hardware systems. This solution is using the Zynq architecture, which contains a processing system of 2-CPU (ARM) and a programmable logic system. (Xilinx FPGA's). using our solution, we can "Dynamically" accelerate part of the software code on the processing system using the partial re- configuration technology, Which enable us to change the FPGA logic while the system is running. By that we break that balance limitation we showed, we can Increase the flexibility of the hardware and can accelerate specific tasks !

We use that concept to create SO files with the same function symbol. But different function implementation The Hardware implementation SO. Burns on-the-fly the required bit stream. And invokes the generated hardware in order to process the data. Main App code Software impl SO Hardware impl SO

The Sobel operator is used in image processing, particularly within edge detection algorithms. Technically, it is a discrete differentiation operator, computing an approximation of the gradient of the image intensity function. Mapping colors as follows: Green -> Blue. Blue -> Red. Red -> Green. המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory

In photography, toning is a method of changing the color of black-and- white photographs. The effects of these processes can be emulated with software in digital photography. SEPIA A common technique of a data filtering for security purpose. Changes the inner representation of the picture (byte array), randomly. Doesn’t change the picture as shown to the user (the human’s eye can’t notice the change). המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory
