These restrictions are due to the fact that PARS needs to compute the total size of a data
communication that occurs at each simulation time step. So far, reliable computations
have only been possible when using the native C data types described in Table 3, above.
In order to transport arbitrary Simulink data types from subsystem to subsystem, it is
necessary to convert to a ‘standard’ elemental data type before the output port of a subsystem. On the
receiving subsystem, the signal is converted back to the ‘actual’ data type after the input port.
3.5. ALLOCATING PROCESSOR RESOURCES
Once a design is partitioned into subsystems, they may be assigned to processor types. This is
accomplished by selecting the subsystem and choosing ‘PARS->Create XXX Task’ from the drop-
down menus of the PARS control panel. Alternatively, PARS provides friendly buttons to do this as
well.

When a subsystem is assigned to a processor type, its outline changes color according to the processor
type it has been assigned. DSP is a shade of
green , while FPGA is a shade of blue . This provides a
visual cue to understand the model partitioning at a glance.

Once a processor type is assigned, double-clicking the subsystem now brings up a PARS-defined mask
that allows attributes assigned to the subsystem to be modified.
