 NVIDIA Tegra
 ============
 
+-  .. rubric:: T194
+      :name: t194
+
+T194 has eight NVIDIA Carmel CPU cores in a coherent multi-processor
+configuration. The Carmel cores support the ARM Architecture version 8.2,
+executing both 64-bit AArch64 code, and 32-bit AArch32 code. The Carmel
+processors are organized as four dual-core clusters, where each cluster has
+a dedicated 2 MiB Level-2 unified cache. A high speed coherency fabric connects
+these processor complexes and allows heterogeneous multi-processing with all
+eight cores if required.
