Abstract
Chips supporting constant time program control of nested loops are provided. In various embodiments, a chip comprises at least one arithmetic-logic computing unit and a controller operatively coupled to the at least one arithmetic-logic computing unit. The controller is configured according to a program configuration, the program configuration comprising at least one inner loop and at least one outer loop. The controller is configured to cause the at least one arithmetic computing unit to execute a plurality of operations according to the program configuration. The controller is configured to maintain at least a first loop counter and a second loop counter, the first loop counter configured to count a number of executed iterations of the at least one outer loop, and the second loop counter configured to count a number of executed iterations of the at least one inner loop. The controller is configured to provide a first indication of whether the first loop counter corresponds to a last iteration and a second indication of whether the second loop counter corresponds to a last iteration. The controller is configured to alternatively increment, reset, or maintain each of the first and second loop counters according to the first and second indications.
