Abstract
A data processing circuit is arranged to execute program instructions defining nested loops. A loop is defined in terms of a start address, an end address and a number of loop iterations. The processing circuit includes a program counter and a plurality of loop counting elements. Each of the loop counting elements includes a start address register, an end address register, a loop iteration register and means for comparing the value stored in the respective end address register with the output from the program counter.
