Figure 1. Initial Configuration Options

Enable Tile<0/1/2>
When you select at least one of the required Enable TILE0/Enable TILE1/Enable TILE2 options, the TILE<0/1/2> tab(s) display.
Tile<0/1/2>
Configuration
Select Basic or Advanced mode.
  • In Basic mode, when the number of inputs for an ISP instance is greater than one, an internal broadcaster is implemented to cater all the input streams of that ISP, while requiring you to provide a single stream input at the IP boundary. You can enable this feature when you have multiple camera data multiplexed through the same source.
  • In Advanced mode, each AXI4-Stream input on the ISP0/1 core requires a separate AXI4-Stream input.
  • In both the Basic and Advanced mode, the maximum total number of AXI4-Stream inputs to ISP0 and ISP1 cores is five.
ISP0 IO Type
Select the ISP0 core input mode: LILO, LIMO, or MIMO.
ISP1 IO Type
Select the ISP1 core input mode: Disable, LILO, LIMO, or MIMO mode. When the number of AXI4-Stream inputs to the ISP1 core is zero, you must select Disable.
ISP0 live inputs
Auto-computed for LILO and MIMO modes. When LIMO is selected for the ISP0 IO Type, you must select 1, 2, 3, or 4.
ISP1 live inputs
Auto-computed for Disable, LILO, and MIMO modes. When LIMO is selected for the ISP1 IO Type, you must select 1 or 2.
ISP<0/1> Memory inputs
Auto-computed based on the ISP<0/1> IO Type parameter. Not user selectable.
Enable 8-to-4PPC Converter
Enable the converter module.
Num of 4k60 streams/VCIDs
Specifies the number of streams the converter module supports.
ISP Instance for Stream<0/1/2/3>
Select the required ISP Tile and Instance from the following options:
  • TILE0 ISP0
  • TILE0 ISP1
  • TILE1 ISP0
  • TILE1 ISP1
  • TILE2 ISP0
  • TILE2 ISP1

The maximum PPC supported on the input streams to ISP is 4. However, in specific use cases, when the total bandwidth from the input camera is greater than 4k60, an 8PPC input stream is accepted and converted to 4PPC internally. The following conditions must met to ensure the functionality of this converter:

  1. The input source must be the MIPI CSI2 RX Subsystem, which has the ability to multiplex multiple camera data, with its pixels set to 8.
  2. You must connect two cameras of equal resolution to the same MIPI input, operating with two different VCIDs.
  3. Each camera’s data from the MIPI interface is sent to a different ISP instance through an internal broadcaster; the ISP MCM (multi-stream) mode is not supported for ISP instances which require this PPC conversion.
  4. The MIPI video_aclk signal must be 300 MHz and the same 300 MHz clock (pl_isp_300m_clk) must be supplied to the Versal ISP Subsystem.
  5. The vidin_clk ports for the inputs selected for PPC conversion must be supplied with a 150 MHz clock.
