Tabula launches first devices
Programmable-logic startup Tabula has launched the first of its devices. Built on a 40nm process at TSMC, the Abax field-programmable gate arrays (FPGAs) use the company’s time-sliced architecture to improve logic density by around three times compared to conventional devices.
Similar to FPGAs from Altera and Xilinx, the Abax chips serial transceivers, providing up to 920 general-purpose parallel I/Os and up to 48 6.5Gb/s serial transceivers. The first four devices all have 5.5MB of on-chip memory and from 220,000 to 630,000 lookup tables.
“We are the only programmable device able to hold a full HD video frame on the chip,” claimed Steve Teig, president and CTO of Tabula.
The largest device adds a thousand multiply-accumulate cores for digital signal processing. As well as the ready-made multiplier blocks, the core fabric has direct support for Booth multiplication, said Teig.
The company said its design flow closely resembles those currently used for FPGAs and ASICs, using synthesis, placement, and routing to compile designs from RTL into silicon.
