17.2. FIR Filter Parameters

The IP offers run- and compile-time parameters.
Table 232.  FIR Filter Parameters
Parameter Values Description
Video Data Format
Input bits per color sample 8 to 16 Select the number of input bits per color sample.
Output bits per color sample 8 to 16 Select the number of output bits per color sample.
Number of color planes 1 to 4 Select the number of color planes per pixel.
Number of pixels in parallel 1 to 8 Select the number of pixels in parallel.
Video Blanking On or off Turn on when the filtered video has blanking
Maximum Frame Size
Maximum field height 32-16384 Specify the maximum height of incoming frames
Maximum field width 32-16384 Specify the maximum width of incoming frames
Filter Parameters
Vertical filter taps 1-16 Height of the FIR filter
Horizontal filter taps 1-16 Width of the FIR filter
Vertical kernel mirroring On or Off Turn on enable vertical symmetry
Horizontal kernel mirroring On or Off Turn on enable horizontal symmetry
Diagonal kernel mirroring On or Off Turn on diagonal symmetry
Rounding method Truncate, round half up or round half even Select the rounding method of choice for the output of the filter
Signed coefficients On or Off Turn on signed coefficients
Coefficient integer bits 0-18 Select the number of the coefficient’s integer bits. The sum of integer bits + fraction bits cannot exceed 18
Coefficient fraction bits 0-18 Select the number of the coefficient’s fraction bits. The sum of integer bits + fraction bits cannot exceed 18
Control Parameters
Runtime control On or off Turn on run-time coefficient loading via the Avalon memory-mapped interface
Use fixed coefficients file On or off Turn on for a fixed coefficient file that the IP loads at compile time
Fixed coefficients file <file path> Specify the fixed coefficients file path
