TILE-Gx

TILE-Gx was a VLIW ISA multicore processor family designed by Tilera. It consisted of a mesh network that was expected to scale up to 100 cores, but only 72-core variants actually shipped.

After a few acquisitions, Tilera's designs ended up in the hands of Nvidia, which ended production of TILE-Gx processors in 2022. In June 2018, the Linux kernel dropped support for this architecture. Tile-Gx processors were used in MikroTik's CCR1000 series routers, and MikroTik continues to support this architecture out-of-tree in its RouterOS Linux distribution.
