A pipelined run-to-completion processor includes no instruction counter and only fetches instructions either: as a result of being prompted from the outside by an input data value and/or an initial fetch information value, or as a result of execution of a fetch instruction. Initially the processor is not clocking. An incoming value kick-starts the processor to start clocking and to fetch a block of instructions from a section of code in a table. The input data value and/or the initial fetch information value determines the section and table from which the block is fetched. A LUT converts a table number in the initial fetch information value into a base address where the table is found. Fetch instructions at the ends of sections of code cause program execution to jump from section to section. A finished instruction causes an output data value to be output and stops clocking of the processor.
