Heap Size

After you select Create heap,thisoptionletsyouspecifythe

size of the heap in words. Enter the number of words in decimal

format. When you enter the heap size in decimal words, the

system converts the decimal value to h exadecimal format. You

can enter the value directly in hexadecimal format as well.

Processors may support different maximum heap sizes.

Deﬁne L a bel

Selecting Create heap enables this option that allows y ou to

name the heap. Enter your label for the heap in the Heap label

option.

Heap Label

Use this option, which you enable by selecting Deﬁne label,to

provide the label for the heap. Any combination of characters

is accepted for the label, except reserved characters in C/C++

compilers.

Note When you enter a label, the block does not verify that the

label is valid. An invalid label in this ﬁeld may cause errors

during code generation.

Cache Conﬁguration

C621x, C671x, and C 641x processors support an L2 cache memory

structure that y ou can conﬁgure as SRAM and partial cache.

Both the data memory a nd the program share this second-level

memory. C620x DSPs do not support L2 cache m emory and

this option is not available when you choose one of the C620x

processors as your processor.

If your processor supports the two-level memory scheme, this

option enables the L2 cache on the processor.

Some process ors support code base m emory organization. For

example, a part of internal memory can be conﬁgure as code.
