Data Store Information

The model.rtw records containing data store information include defaults for the data types and an indication whether or not the data is complex. The primary purpose of the DataStore record is to set up memory for implementing the data store. Each instance of a Data Store Read block that uses the same data store variable name is allowed to read the memory location(s) while Data Store Write blocks are allowed to write to the designated memory location(s). Data Store Read and Data Store Write blocks are placed under the block instance section of the model.rtw file.

Table A-10: Model.rtw Data Store Information 

Variable/Record Name	Description
DataStoreDefaults {	Defaults for the data store records.
DataTypeIdx	0: Default is real_T.
ComplexSignal	no: Default is not complex.
}
DataStores {	Record giving the data stores found in the block diagram.
NumDataStores	Number of data stores in the block diagram.
DataStore {	One record for each data store.
Name	Name of block declaring the data store.
SLName	Unmodified Simulink name. This is only written if it is not equal to Name.
MemoryName	Name of the data store memory region.
Identifier	Unique identifier across all data stores.
Index	[dataStoreIndex, dataStoreWidth].
Dimensions	Vector of the form [nRows, nCols] for the signal. Only written if number of dimensions is greater than 1.
InitValue	Initial value for the data store.
