Figure 19 - Select subsystem and create DSP Task
This figure shows the process of assigning a subsystem to a processor type. In the figure above, we
select the ‘Add’ subsystem, then use the PARS control panel to ‘Create DSP task’ for this subsystem.
This act masks the ‘Add’ subsystem, and enables PARS to attach several attributes needed to facilitate
code generation for the subsystem.
In the same way, the next two slides show how the ‘Host’ subsystem is assigned as the host task by
using the PARS control panel to ‘Create Host task’.
If a subsystem has been assigned, double-clicking it brings up the mask parameters which allow
manipulation of the attributes that PARS stores for each subsystem. See Figure 22, below for the
attributes that are available for the DSP task. Notably, the ‘Target Processor’ field is shown which
allows you to control the kind of DSP (fixed/floating point) you intend the subsystem to execute on.
The ‘Automatic’ is the most versatile, in which the processor type is obtained from the hardware
description, based on the assignment.
A masked subsystem must use ‘Look under mask’ in order to see the underlying blocks comprising it.
Do this for the ‘Host’ subsystem in preparation for simulation and code generation. See Figure 23,
below.
