Other Custom Storage Classes

This section discusses other custom storage classes that have been provided for special purposes.

GetSet Custom Storage Class
for Data Store Memory

The GetSet custom storage class can only be used for the memory of Data Store Read and Data Store Write blocks. The properties of the GetSet class are summarized in Table 4-4 and Table 4-5.

This class supports only signals of noncomplex data types. Its purpose is to generate code that reads (gets) and writes (sets) data via functions. For example, if the GetFunction for signal x is specified as "get_x" then the generated code will call get_x() wherever the value of x is used. If the SetFunction for signal x is specified as "set_x" then the generated code will call set_x(value) wherever the value of x is assigned.

For wide signals, an additional index argument is passed, as in

• get_x(idx)
  set_x(value, idx)
  

The cscgetsetdemo demo illustrates the use of the GetSet custom storage class.
