Abstract
Techniques are disclosed relating to clock routing techniques in processors with both pipelined and non-pipelined circuitry. In some embodiments, an apparatus includes execution units that are non-pipelined and configured to perform instructions without receiving a clock signal. In these embodiments, one or more clock lines routed throughout the apparatus do not extend into the one or more execution units in each pipeline, reducing the length of the clock lines. In some embodiments, the apparatus includes multiple such pipelines arranged in an array, with the execution units located on an outer portion of the array and clocked control circuitry located on an inner portion of the array. In some embodiments, clock lines do not extend into the outer portion of the array. In some embodiments, the array includes one or more rows of execution units. These arrangements may further reduce the length of clock lines.
