HIGH-LEVEL LIBRARY MAPPING FOR ARITHMETIC COMPONENTS

We describe high-level library mapping (HLLM), a technique that permit s reuse of complex RT-level databook components (specifically ALU's). HLLM can be used to couple existing databook libraries, module generat ors and custom-designed components with the output of architectural or behavioral synthesis, In this paper, we define the problem of high-le vel library mapping, present some algorithmic formulations for HLLM of ALU's, and demonstrate the versatility of our approach on a variety o f libraries, We also compare HLLM against the traditional mapping appr oach using logic synthesis, Our experiments show that HLLM for ALU's o utperforms logic-synthesis in area, delay, and runtime, indicating tha t HLLM is a promising approach for reuse of datapath components in arc hitectural design and high-level synthesis.
