Error Correcting Tensor Processor Unit (EC-TPU™)

MaiTRIX’s forward error-correcting technology is combined with its RNS-TPU™ to provide the world’s first error correcting matrix arithmetic!

Extreme Reliability TPU

The EC-TPU™ is extremely resilient to transient bit errors from sources as diverse as over-clocking and over-heating, and from single and multiple event error sources in outer space, such as gamma rays and neutron particle strikes. No other processor architecture comes close. Prior art technology, such as binary matrix processors configured in a triplicate voting configuration, cannot correct more simultaneous errors than DSR’s new EC-TPU™ error correcting TPU technology!

For FPGA based designs, our EC-TPU™ can operate and deliver continuously corrected matrix arithmetic during critical single event upsets (SEU) and multiple event upsets (MEU), even when these events are located in the configuration RAM (CRAM) cells of FPGA devices.  When CRAM is corrupted, the circuit configuration of the ALU actually changes.  For example, one entire digit circuit of the EC-TPU™ matrix multiplier may be rendered faulty when a CRAM cell changes, yet the matrix arithmetic will not be affected.  Un-like the case of triplicate redundancy, with Maitrix technology the exact point of failure can be instantly located, and the local CRAM configuration can be repaired.

MaiTRIX’s error correcting technology requires a 50% increase of total arithmetic circuitry and corrects multiple, simultaneous errors versus triplication schemes which require a 200% increase in arithmetic circuitry yet cannot correct multiple, simultaneous errors.

Extreme Reliability Meets Extreme Efficiency

When MaiTRIX’s new error correcting technology is combined with its RNS-TPU™ technology, we call it extreme reliability meets extreme efficiency! … a perfect combination for advanced space-based AI applications!

For off the shelf solutions, our EC-TPU™ IP cores are tailored to run on Arria 10, Stratix 10, and Agilex FPGA devices from Intel.  Demonstration cores are available for popular development boards from Intel and Terasic.  MaiTRIX IP supports a wide range of Intel based accelerator cards to support applications that demand high-performance, high precision, and high efficiency combined with very high reliability.
