Here are some of the most frequently asked questions about Gedae. You are welcome to submit your own questions to the Gedae team at gedae@gedae.com

• What specific environments does Gedae support?
• Can Gedae be ported to custom hardware?
• Is there a system requirement of using a slot-1 controller?

• Is there a limit to the number of function boxes?
• Can I control the Gedae table entries to display the information of only one hierarchical box?
• Can GUIs be used with Gedae applications/launch packages?
• Can a Gedae application be fault tolerant?
• How can we archive all information for a flow graph - graphs, primitives, parameter settings, group settings, etc.?
• Does Gedae support automated requirements traceability?
• How can one get a figure for the number of C source instructions generated by Gedae for an embedded application?

• Is the source code to the Gedae libraries available for modification and extension as you build your own library functions?
• Does the Gedae library use single or double precision functions?
• When will an improved description of the primitive library be available? When will the individual primitives have better descriptions? Can the box comments be viewed? How is the library validated?
• How can cyclic primitives be used to reduce latency and improve memory usage?
• Will and, if so, when will a library of Gedae function boxes equivalent to the MATLAB core and signal processing functions be available?
• When will Gedae use a VSIPL compliant library?

• What are the specific data transfer methods for processor to processorcommunications supported by Gedae?
• How much does Gedae support RT control systems? For example, weapons control or flight control?

• What is the default processor?
• Does Gedae provide any specific support for evaluating applicationprecision requirements?
• Does Gedae determine and display bus loading the way it displays softwarefunction execution and individual DSP loading?
• Having put two processes on the same processor, how efficiently will Gedae switch between the two?

• What mechanism(s) is (are) available to ensure that parameter changes aresynchronized with the data to which the changes apply?
• Is there a way to aggregate a group of parameters, such as through a userdefined data type (perhaps in conjunction with user defined primitivesto do packing and unpacking), for the purposes of distribution and synchronization in an embedded environment?
• What functionality in the Command Program Interface supports changing the value of parameters used by a running graph? Does the command program suspend and resume the execution of the graph or just change the parameter values on the fly?

• Can Gedae applications be divorced completely from a workstation?
• What are the details of the Command Program Interface (CPI)?

• Can I print graphs and tables?
• Can Gedae export to HTML (for example - for peer level reviews without using an extra license)?

• How can external software and hardware resources be accessed from an application built in Gedae?
• How do I use functions from external libraries in a Gedae function box?
• How do I call C++ functions from Gedae function boxes using the Microsoft Visual C++ compiler?
• Does Gedae support the direct connection of I/O devices to graphs?
• How can Gedae access shared memory from a primitive?
• How can Gedae interface with a larger system?
• How can MATLAB be integrated with Gedae?
• How can Gedae access a database using primitives?

• When will a bug list be available?
• How do I use a source code debugger to debug Gedae primitives?
• When running the Gedae Development Environment on Windows, why does Gedae stop responding to mouse inputs and stop refreshing?
• To get an embedded only graph to run it is necessary to select one of the boxes in the graph and turn on the Options->Sink menu toggle. This is easy to overlook, and it is confusing that the graph does not run.
• Sometimes the "state" data structure is corrupted. What is the state vector? How can I fix the problem?
• When will the flattened graph be less cumbersome for large graphs?
• The file dialog seems primitive and is hard to use. Are there any plans to enhance it?
• When is it legal/illegal to use user-defined datatypes in Gedae primitive interface declarations?
• Why can't I open files from an application that is mapped to a VxWorks processor?
• What do I need to do to be able to use the Exceed Version 7.1 XDK?
• What do I need to do to be able to use the Exceed Version 9.0 XDK?

• Are there any restrictions on the export of Gedae?
• Is formal training available for Gedae?
