In the section Create a Spider workflow, one of the instruction is to use the plugin identifier as

plugin identifier : “org.ietr.Preesm.pimm.algorithm.spider.codegen.SpiderCodegenTask”

A screenshot is here reported:

that does not work and generates an error.

The error disappears when replacing the capital letter P of the word Preesm with the correspondent lower-case.

When downloading the c6678 source files for the C6678 project in the Multicore DSP tutorial, the announced yuv2dat project is no longer included in the downloaded files.

In the tutorial 12 of the preesm website called "Throughput Evaluation for Hierarchical graphs", it seems that the example project is not available.

In the sobel tutorial, first and last line of the output image are not properly set before being displayed, which may cause variations at each code generation.

To solve the issue:

• Sequential sobel: The sobel actor should set to black lines the first and last line of its outpit
• Parallel sobel: in the merge actor, the first and last line of the output should be set to black lines also.

In both case, adding the following code to the actors is sufficient:

memset(output, 0, width);
memset(output + (height - 1)*width, 0, width);

In the sobel tutorial, it is asked to open the single-rate intermediate graph to understand its content.

2 problems arise:

• The DAG is exported by the given workflow, but not the single-rate graph.
• The graphml file can not be opened by latest version or Preesm.

I am trying to access to the memory scripts provided by this tutorial (Advanced Memory Footprint Reduction) , however, the webpage is not available anymore.

Could you provide me with these memory scripts?

Thank you

In section "Implementation of the new workflow task", the Java class given introduces a mistake : exceptions thrown are typed PreesmException, which is an abstract class and cannot be instantiated. I replaced it with PreesmRuntimeException.

Location : line 41 and 70

throw new PreesmException(message);
