7.9. Encoder Parameters
The following table lists the parameters for the ALTECC encoder IP core.
Parameter Name | Type | Required | Description |
---|---|---|---|
WIDTH_DATAWORD | Integer | Yes | Specifies the width of the raw data. Values are from 2 to 64. If omitted, the default value is 8. |
WIDTH_CODEWORD | Integer | Yes | Specifies the width of the corresponding code word. Valid values are from 6 to 72, excluding 9, 17, 33, and 65. If omitted, the default value is 13. |
LPM_PIPELINE | Integer | No | Specifies the pipeline for the circuit. Values are from 0 to 2. If the value is 0, the ports are not registered. If the value is 1, the output ports are registered. If the value is 2, the input and output ports are registered. If omitted, the default value is 0. |
