Description

At time step n, the Accumulator block computes a cumulative sum of all input values u up to time n and outputs the sum.
Parameters and Dialog Box

- Initial condition for previous output
- Set the initial condition for the previous output.
- Output data type and scaling
- Specify the output data type and scaling via the dialog box, or inherit the data type and scaling from the driving block or by backpropagation.
- Round toward
- Rounding mode for the fixed-point output.
- Saturate to max or min when overflows occur
- If selected, fixed-point overflows saturate.
