Targ et Preferences

Adding the ne w processor puts the processor on the Processor

list for all Target Preferences blocks, not just this one.

The new processor and conﬁgura tion b ecome available for all

models that include a Target Preferences block.

For details about the New Process or dialog box, refer to New

Processor Dialog B ox .

Edit

Edit the conﬁguration for the proces sor you sele ct o n the

Processor list.

Delete a processor that y ou added to the Processor list. You

cannot delete processors that you did not add.

CPU Clock Speed (MHz)

Shows the clock speed of the processor on your processo r. When

you enter a value, you are not changing the CPU clock rate. You

are reporting the actual rate. If the value you enter does not

match the rate on the processor, your mo del’s real- time results

may b e wrong, and the code proﬁling results are not correct.

Enter the actual clock rate the board uses. The rate you enter in

this ﬁeld does not change the rate on the board. Setting CPU

clock s peed to the actual board rate allows the code you generate

to run correctly according to the actual clock rate of the hardware.

When you generate code for C6xxx processors from Simulink

software models, you may encounter the software timer. The

timer is invoked automatically to handle and create interrupts to

drive your model when either of the follow ing conditions occur:

• Your model does not include ADC or DAC blocks

• When the process ing rates in your m odel change (the m odel

is multirate)
