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.
