Abstract

Systems and methods are disclosed for fault-tolerant hash control. In some examples, a hashing system receives a dataset. The controller apportions hashing calculations across hashing chips to calculate at least one hash digest based on the dataset. The hashing chips include at least a first hashing chip, a second hashing chip, and a third hashing chip. A first connector couples the first hashing chip to the second hashing chip. A second connector couples the second hashing chip to the third hashing chip. A backup connector couples the first hashing chip to the third hashing chip, bypassing the second hashing chip. The first hashing chip sends a communication to the third hashing chip along the backup connector that bypasses the second hashing chip in response to a determination that the second hashing chip is nonresponsive.

Dependent claims

A system for hashing management, the system comprising:

a circuit board;
a controller that receives at least one dataset;
a plurality of hashing chips on the circuit board, wherein the plurality of hashing chips are coupled to one another and to the controller using a plurality of connectors on the circuit board, wherein the controller sends a plurality of hashing communications to the plurality of hashing chips to apportion hashing calculations across the plurality of hashing chips and to calculate at least one hash digest based on the at least one dataset, wherein the plurality of hashing chips includes at least a first hashing chip and a second hashing chip and a third hashing chip;
and
the plurality of connectors, wherein the first hashing chip is coupled to the second hashing chip using at least a first connector of the plurality of connectors, wherein the second hashing chip is coupled to the third hashing chip using at least a second connector of the plurality of connectors, and wherein the first hashing chip is coupled to the third hashing chip using at least a backup connector of the plurality of connectors that bypasses the second hashing chip, wherein the backup connector is automatically activated and the first connector and the second connector are automatically deactivated in response to a determination that the second hashing chip is nonresponsive to a first hashing communication, the first hashing communication sent from the controller toward the second hashing chip through the first hashing chip and the first connector, wherein a second hashing communication is conveyed between the first hashing chip and the third hashing chip through the backup connector while the backup connector is activated, and wherein the plurality of hashing communications include the first hashing communication and the second hashing communication.
