37.3.1. Block Cache Tool

This tool estimates the minimum suggested size of the warp IP engine’s block cache for the given transform and the number of processing engines. You can use the block cache tool at the design stage to help estimate required FPGA resources and evaluate warps specific to the customer application.

The block cache tool also detects if the configured transform creates a local compression higher than 2:1, which is the maximum supported compression value of the Warp IP. The block cache tool supports both single bounce and double bounce warp IP configurations.

The block cache tool provides a command line interface that allows you to specify the desired warp by using several available options such as rotation, mirroring, keystone, or by using a warp mesh file generated by the Warp SoC Design Example. The tool then estimates block cache usage for all supported block cache sizes. For each size option the tool prints the result in the following form:

Table 678.  Tool Results
Result Description
Pass Requested warp is possible using this block cache size per processing engine
Pass, Block cache usage too high Requested warp might be possible. However the IP does not guarantee the output quality because of high block cache usage. The configuration requires further evaluation on the target system
Fail Requested warp is not possible using this block cache size. The estimation also fails if the warp exceeds a maximum supported local compression of 2:1, in which case it fails for all block cache sizes

The block cache tool can visualize configured transform by warping a reference image and saving it as a bitmap (bmp) file on the disk.

The block cache tool is delivered with Intel Quartus Prime Software as a Windows command line application at the following location:

<INSTALL_DIR>/ip/altera/vvp/component_library/tcl_cores/intel_vvp_warp/sw/block_cache_tool/windows/bct.exe

where <INSTALL_DIR> is the installation folder of the Intel Quartus Prime software.

-s

Run warp simulator

Warp a reference image using provided settings and save result on disk. The output file name is warp_output.bmp.

Examples

This command:

bct.exe -iw 1920 -ih 1080 -ow 3840 -oh 2160 -r 15.0 -s

  • Sets the input resolution to full HD, output resolution to 4K
  • Performs a 15 degree rotation anticlockwise
  • Stores warped reference image on the disk.

The console output is:

intel_vvp_warp block cache tool v1.0
Input resolution: 1920x1080
Output resolution: 3840x2160
Warp engines: 2
Bounce: Single
Generating warp data..
Cache size Result Warnings
256 PASS
512 PASS
1024 PASS

The console output indicates the IP can perform the configured warp with all available block cache size options.

Figure 96. Warped reference image

This command:

bct.exe -f flying_flag.owf -ec -s

  • Uses the warp mesh file generated by the Warp SoC Example Design, named flying_flag.owf
  • Uses default input and output resolution of 4K
  • Ignores 2:1 local compression limit
  • Stores warped reference image on the disk.

The console output is:

intel_vvp_warp block cache tool v1.0
Input resolution: 3840x2160
Output resolution: 3840x2160
Warp engines: 2
Bounce: Single
Generating warp data...
Cache size Result Warnings
256 PASS Block cache usage too high
512 PASS
1024 PASS

The console output indicates the IP can perform the warp using block cache sizes of 512 and 1024. With the block cache size of 256, the tool detects a high block cache usage. The IP cannot guarantee the output image quality and requires further evaluation on the actual hardware.

Figure 97. Warped reference image

This command:

bct.exe -z 0.45
  • Uses default input and output resolution of 4K
  • Scaled the image down by 0.45

The console output is

intel_vvp_warp block cache tool v1.0
Input resolution: 3840x2160
Output resolution: 3840x2160
Warp engines: 2
Bounce: Single
Generating warp data..
Cache size Result Warnings
256 FAIL
512 FAIL
1024 FAIL

Fails to generate warp data for the given transform using available cache options. Check the transform does not exceed 2:1 compression limit

The console output indicates you have exceeded the maximum compression of 2:1 and therefore the hardware does not support it.
