SigmaStudio Cells and Cell Parameters
This interactive list has the SigmaStudio Cells extracted from the SigmaStudio project. A cell is a block in the
SigmaStudio project, which is controlled by a set of parameters. Figure 48 below shows an example of a filter.
Clicking the cells in the list, the Cell parameters window is updated with the parameters related to that cell. Once a
cell is selected, it can be added to a register using the Add cell to register function.
Figure 48: SigmaStudio Cells and Parameters
Figure 49: The cell as it appears in SigmaStudio
SigmaStudio Cells list has three elements:
Name: Name of the cell, matches the SigmaStudio cell name, and is set by the user when developing the audio flow
in SigmaStudio. In the example above, Gen Filter1 is the name of the highlighted cell. Note: Just like variables when
programming in C or any other programming language, Cell names in SigmaStudio should be given names
descriptive of their purpose. This makes it easier for the user when creating their Application Layer.
Cell Type: Detected cell type. This value is used by the register creation wizards, so depending on the type, a wizard
matching it will be loaded. The selected cell above (Figure 48), will load a Filter Wizard, since its type is Filter Dual.
Parameters: List of parameters related to the cell (internal SigmaStudio numbers). The Cell parameters window
below the SigmaStudio Cells windows (Figure 48), shows more details about them.
Cell Parameters list has two elements:
Address: Actual parameter memory address in the parameter memory map (hexadecimal value). Writing to this
value directly would change the parameter value. This should be only done for development and debug purposes,
and is not supported from the Application Layer GUI.
Parameter Name: Name of the selected parameter.
Parameters (Names and Addresses), that
are controlled by the cell. E.g. 2
nd
order IIR
Filter – 5 coefficients
