Library mapping for memories

We present a library mapping technique that synthesizes a source memory module from a library of target memory modules. We define the library mapping problem for memories, identify and solve the three subproblems of port., bit-width and size (word) mapping associated with this task and finally combine these solutions into an efficient memory mapping algorithm. Experimental results on a number of memory-intensive designs demonstrate that our memory mapping approach generates a wide variety of cost-effective designs, often counter-intuitive ones, based on a user-given cost function and the target library.
