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 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.
Selected Cell
Same cell in SigmaStudio
Parameters (Names and Addresses), that
are controlled by the cell. E.g. 2
nd
order IIR
Filter – 5 coefficients
