Abstract
The present invention discloses a processor for computing a mathematical function. The processor comprises a look-up table circuit (LUT) and an arithmetic logic circuit (ALC). The LUT is formed on the backside of the processor substrate and stores data related to the mathematical function. The ALC is formed on the front side of the processor substrate and performs arithmetic operations on the function-related data. The LUT and the ALC are communicatively coupled by a plurality of through-silicon vias (TSV).
