| Abstract: | A high-throughput matching memory (MM) for a data-driven microprocessor is discussed. An MM can be constructed using a hashing memory. However, one of the biggest problems with hashing memory is the necessity for selective processing whenever hashed address conflicts occur. To eliminate this problem, the MM incorporated a small amount of associative memory (32 words×50 b) as well as the hashing memory (512 words×42 b). The matching operation is subdivided into three pipeline stages, all controlled by the elastic pipeline scheme. With this structure, an MM with a high throughput of 100-mega-access/s MM can be realized |
