A byte RAM helps to form output frames by any combination 13 of bytes from the input frame. Its design is identical to that of byte 14 RAM in the AMX except that the data flow direction is reversed. 15 16maintainers: 17 - Jon Hunter <jonathanh@nvidia.com> 18 - Mohan Kumar <mkumard@nvidia.com> 19 - Sameer Pujar <spujar@nvidia.com> 20 21allOf: 22 - $ref: name-prefix.yaml# 23 24properties: 25 $nodename: 26 pattern: "^adx@[0-9a-f]*$" 27 28 compatible: 29 oneOf: 30 - const: nvidia,tegra210-adx 31 - items: 32 - enum: 33 - nvidia,tegra194-adx 34 - nvidia,tegra186-adx 35 - const: nvidia,tegra210-adx 36 37 reg: 38 maxItems: 1 39 40 sound-name-prefix: 41 pattern: "^ADX[1-9]$" 42 43 ports: 44 $ref: /schemas/graph.yaml#/properties/ports 45 description: | 46 ADX has one input and four outputs.
