However, if multiple audio channels are required,&nbsp; the TX1\/TX2 is limited to I2S audio inputs. Utilizing the MIPI\u00ae Camera Serial Interface (CSI-2) and the InES I2S to CSI-2 converter IP, enables&nbsp; streaming of up to 256 digital audio channels into the TX1\/TX2.<\/p>\n<p>Institute of embeddeded Systems (InES) developed an FPGA-IP which converts the&nbsp; I2S audio to&nbsp; up to four CSI-lanes for feeding audio into mobile processors like the NVIDA Tegra&#x2122; TX1\/TX2.<\/p>\n<p>A Linux driver, which links the received CSI signals to the Tegra&#x2122; TX1\/TX2 processor buses, is also available. Hence, audio can be processed on the TX1\/TX2 GPU or the internal audio blocks.<\/p>\n<p>I2S sources could be audio codecs, SDI or HDMI chips. The CSI-2 protocoll engine can be configured&nbsp; to generate CSI-2 data packets for one or four CSI lanes, depending on the required bandwidth. The CSI clock and data physical interfaces support differential (high speed) and low power CSI-2 signals.<\/p>\n<p>The IP is written in VHDL and tested with Intel Cyclone-IV FPGAs. It is also possible to be synthesized into Xilinx or Lattice FPGAs.<\/p>\n<p>For more information contact Hans-Joachim Gelke (hans.gelke@zhaw.ch)<\/p>\n<figure id=\"attachment_133\" aria-describedby=\"caption-attachment-133\" style=\"width: 720px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-133 size-full\" src=\"http:\/\/blog.zhaw.ch\/high-performance\/files\/2018\/07\/csi_block.png\" alt=\"\" width=\"720\" height=\"343\" srcset=\"https:\/\/blog.zhaw.ch\/high-performance\/files\/2018\/07\/csi_block.png 720w, https:\/\/blog.zhaw.ch\/high-performance\/files\/2018\/07\/csi_block-300x143.png 300w, https:\/\/blog.zhaw.ch\/high-performance\/files\/2018\/07\/csi_block-676x322.png 676w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><figcaption id=\"caption-attachment-133\" class=\"wp-caption-text\">Block Diagramm of I2S to CSI IP<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The NVIDA Tegra&#x2122; Processors TX1\/TX2 with their powerful GPUs are ideal for use in professional audio mixing consoles or audio video equipment.
