iam provides 64-bit processor scalability while combining real-time control with soft and hard engines for graphics and video. With the NET SDK and GigE Vision toolboxes shown below customers can start comfortably to build their unique vision system with iam. The open system architecture of iam enables customers to use both CPU and FPGA processing resources for their application.

Introducing the NET Open Camera Concept for iam
In section you will find a varius various software example application where we briefly described how to optimize the application code by using hardware acceleration by synthesizing a FPGA co-processor into the programmable logic of the camera.

The figure below illustrates the described steps above and the following table summarizes the example projects.
ccode_synview | cross | The example code_synview uses HLS hw acceleration written in C-code. The main processing method can be selected among following choices:
After processing the image is sent out via GigE Server. |
|---|---|---|
remap_synview | cross | The example remap_synview uses the hardware acceleration function xf::cv::remap from the Vitis vision library. After processing, the image is sent out via GigE Server. |
remap_boxfilter_synview | cross | The example remap_boxfilter_synview uses the hw acceleration function xf::cv::remap from the Vitis vision library and the cv::remap and cv::boxfilter function from OpenCV. After processing, the image is sent out via GigE Server. |
rtl_threshold_synview | cross | This example uses RTL hardware acceleration written in verilog. After processing, the image is sent out via GigE Server. |
rtl_threshold_synview_dfx | cross | This example uses RTL hardware acceleration written in verilog. It consists of two different threshold accelerators, but only one of them can be loaded into the programmable logic. The module can be changed dynamically during running acquisition. This function is called DFX (Dynamic Function eXchange) and can help to use different accelerators that wouldn't fit together in the fpga part. After processing, the image is sent out via GigE Server. |
strm_boxfilter_synview | cross | This example uses HLS hardware acceleration with the xfOpenCV function xf::cv::boxfilter in the streaming path. After processing, the image is sent out via GigE Server. |
strm_rtl_threshold_synview | cross | This example uses RTL hardware acceleration in the streaming path. After processing, the image is sent out via GigE Server. |
sw_scaler_synview | cross | This example uses no hardware acceleration. After processing the image is sent out via GigE Server. |
sw_frm_buf_config_synview | cross | This example uses no hardware acceleration But it uses the same infrastructure like other hw accelerated examples. The application does no processing. The purpose of the app is to demonstrate how to configure (buffer-number, number of max. buffer delay) the input frame buffer manager. After processing the image is sent out via GigE Server. |

Background and Strategy
Hardware Acceleration: Optimizing Effects
The processing power of iam can be improved by FPGA optimization effects such as pipelining, parallelization, co-processing , and quantization.
Hardware Acceleration: Kernels Types
The figure below shows different methodes of writing acceleration kernels for iam. Most of the different ways are covered by a software example in the net-gmbh/iam_apps repository.
Introduction to Cross Compiling
| Info |
|---|
Cross-compilation is the act of compiling code for one computer system (often known as the target) on a different system, called the host. |
