28.2. Scaler IP Parameters
Parameter | Allowed range | Description |
---|---|---|
Video data format | ||
Lite mode | On or off | Turn on to use the lite variant of the Intel FPGA Streaming Video protocol. |
Bits per color sample | 8 to 16 | Select the number of 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 transmitted every clock cycle. |
444 chroma sampling | On or off | Turn on to support scaling of 444 chroma sampled video data. |
422 chroma sampling | On or off | Turn on to support scaling of 422 chroma sampled video data. |
420 chroma sampling | On or off | Turn on to support scaling of 420 chroma sampled video data. |
Disable flush/fill between frames | On or off | Turn on to turn off the flush and refill of the line buffer between frames. |
Maximum input field width | 1 to 65536 | Set the maximum supported input field width. If you turn on horizontal partial scaling, the value in this parameter specifies the size of the internal line buffer. The value you specify should be the maximum number of pixels expected per line in the tile of the overall image that this scaler processes, including any overscan data. |
Maximum output field width | 1 to 65536 | Set the maximum supported output field width. If memory-mapped control of the scaler settings at runtime is not enabled, then this value sets the fixed output field width. If you turn on horizontal partial scaling, this parameter sets the precision of the internal fixed-point arithmetic to calculate the pixel drop and repeat patterns. Set this value to the size of the maximum expected input or output image before tiling, which is the maximum overall input or output image width |
Output Picture Height | 1 to 65536 | Set the height for the output fields. Only used if memory-mapped control of the scaler settings at runtime is not enabled. |
Control settings | ||
Memory-mapped control interface | On or off | Turn on for the Avalon memory-mapped control agent interface and to allow runtime configuration via the register map. You must have the Avalon memory-mapped control agent interface if you turn on Lite mode. |
Scaling | ||
Scaling algorithm | Nearest Neighbor, Bilinear, Filtered | Select the algorithm to resize the video fields |
Runtime coefficient updates | On or off | Only with Polyphase. Turn on for updates to the scaling coefficients at runtime via the Avalon memory-mapped control agent interface. |
Initialize coefficients at startup | On or off | Only with Polyphase. Turn on to initialize the scaling coefficients to pre-set values at startup. |
Vertical scaling | ||
Vertical scaling | On or off | Turn on for image resizing in the vertical direction |
Vertical partial image scaling | On or off | Turn on for partial image scaling in the vertical direction |
Mirror 420 chroma data | On or off | Only with 420 chroma sampling on. Turn on to reduce the memory resources required to implement the line buffer for scaling 420 sampled data (refer to 422 and 420 Chroma Sampled Data Scaling) |
Number of vertical taps | 1 to 64 | Polyphase only. Set the number of vertical scaling filter taps |
Number of vertical phases | 2 to 256 | Polyphase only. Set the number of vertical scaling filter phases |
Number of vertical banks | 1 to 16 | Polyphase only. Set the number of vertical scaling filter coefficient banks |
Use signed vertical coefficients | On or off | Polyphase only. Turn on to use signed coefficients for the vertical scaling filter |
Vertical coefficient integer bits | 0 to 17 | Polyphase only. Set the number of integer bits used to represent the vertical scaling filter coefficients |
Vertical coefficient fraction bits | 1 to 18 | Bilinear and polyphase only. Set the number of fraction bits to represent the vertical scaling filter coefficients |
Fraction bits preserved between vertical and horizontal scaling | 0 to vertical coefficient fraction bits | Bilinear and polyphase only. Set the number of fraction bits to preserve in the intermediate result between the vertical and horizontal scaling pipelines |
Horizontal scaling | ||
Horizontal scaling | On or off | Turn on for image resizing in the horizontal direction |
Horizontal partial image scaling | On or off | Turn on for partial image scaling in the horizontal direction (see Partial Frame Scaling) |
Number of horizontal taps | 1 to 64 | Polyphase only. Set the number of horizontal scaling filter taps |
Number of horizontal phases | 2 to 256 | Polyphase only. Set the number of horizontal scaling filter phases |
Number of horizontal banks | 1 to 16 | Polyphase only. Set the number of horizontal scaling filter coefficient banks |
Use signed horizontal coefficients | On or off | Polyphase only. Turn on to use signed coefficients for the horizontal scaling filter |
Horizontal coefficient integer bits | 0 to 17 | Polyphase only. Set the number of integer bits used to represent the horizontal scaling filter coefficients |
