Tabula calls its technology Spacetime 3D because it uses time, rather than space, as a third dimension, reprogramming every resource on the chip to perform multiple, different functions per user cycle – up to 12 in the 22nm generation.

The chip’s resources are distributed across 12 floors, which Tabula calls folds, to reduce the die size.

All the components in the Tabula ICs – logic, RAM, multiply/accumulate blocks, and interconnect – operate in concert at up to 2GHz.

The company was one of Intel’s first customers for 22nm foundry and is said to have received capital from Intel. In all it raised some $200 million.

Tabula produced three reference designs:

A 12x10G‐to‐100G bridge used in communications systems.

A 4x100G switch for data centre migration from 10G to 40G and 100G.

A Ternary Search Engine (TSE) delivering search for routers.
