TILE-Gx

TILE-Gx was a VLIW ISA multicore processor family designed by Tilera. It consisted of a mesh network[7] that was expected to scale up to 100 cores,[8] but only 72-core variants actually shipped.[9]

After a few acquisitions, Tilera's designs ended up in the hands of Nvidia, which ended production of TILE-Gx processors in 2022.[1] In June 2018, the Linux kernel dropped support for this architecture.[10] 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.

Product lineup

Common features of TILE-Gx processors:

  • 64-bit VLIW RISC core (3-issue)
  • 4 MAC/cycle with SIMD extensions
  • L1 cache: 64 KB (32 KB data + 32 KB instruction) per core.
  • L2 cache: 256 KB per core.
  • L3 cache: Other core's L2 cache connected via mesh network.
  • 1, 2, or 4 ECC 72-bit DDR3 controllers.
  • Up to 24 PCIe 2.0 lanes.
  • Optional built-in crypto accelerator with 40 Gbit/s encryption (small packet) and 20 Gbit/s full-duplex compression, true random number generator, RSA accelerator.
  • Fabrication process: TSMC 40nm.
