Library mapping for memories
Pradip K. Jha, Nikil D. Dutt · 1997
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 memoryintensive designs demonstrate that our memory mapping approach generates a wide variety of cost-effective designs, often counter-intuitive ones, based on a usergiven cost function and the target library. 1 Introduction Digital systems are typically decomposed into datapaths, controllers and memories. With the increasing importance of high-speed data intensive applications in the fields of speech, image and video processing that require significant amount of storage capability, the memory subsystem becomes an important focus of design. For such applications, the area cost of memory compon...
