 GCU, which refers to General Compute Unit, is a type of accelerator card that is used to perform general-purpose computing tasks just like GPGPU.
 
+### Tenstorrent
+
+NVTOP supports Tenstorrent AI accelerators (Blackhole, Wormhole, Grayskull) through the [tt-kmd](https://github.com/tenstorrent/tt-kmd) kernel driver.
+
+Supports temperature, power draw, AI clock, fan RPM, PCIe link info, and process listing. No external libraries required -- all data is read from sysfs, hwmon, and procfs.
