3.4. FIR II IP Core Input and Output Options
Parameter | Value | Description |
---|---|---|
Input Options | ||
Input Type | Signed Binary Signed Fractional Binary |
Signed binary or signed fractional binary format input data. Select Signed Fractional Binary to monitor which bits the IP core preserves and which bits it removes during the filtering process. |
Input Width | 1–32 | The width of the input data sent to the filter. |
Input Fractional Width | 0–32 | The width of the data input into the filter when you select Signed Fractional Binary as your input data type. |
Output Options | ||
Output Type | Signed Binary Signed Fractional Binary |
Signed binary or a signed fractional binary format output data. Select Signed Fractional Binary to monitor which bits the IP core preserves and which bits it removes during the filtering process. |
Output Width | 0–32 | The width of the output data (with limited precision) from the filter. |
Output Fractional Width | 0–32 | The width of the output data (with limited precision) from the filter when you select Signed Fractional Binary as your output data. |
Output MSB Rounding | Truncation/ Saturating | Truncate or saturate the most significant bit (MSB). |
MSB Bits to Remove | 0–32 | The number of MSB bits to truncate or saturate. The value must not be greater than its corresponding integer bits or fractional bits. |
Output LSB Rounding | Truncation/ Rounding | Truncate or round the least significant bit (LSB). |
LSB Bits to Remove | 0–32 | The number of LSB bits to truncate or round. The value must not be greater than its corresponding integer bits or fractional bits. |
