CONFIGURATION MEMORY IMPLEMENTATION FOR LUT-BASED RECONFIGURABLE LOGIC ARCHITECTURES

摘要

A reconfigurable processing unit ( 1 ) is described which comprises, data flow controlling elements ( 10 ), data manipulating elements ( 20 ), a configuration memory unit ( 30 ) comprising a plurality of memory cells ( 31 a, . . . ) for storing settings of the data flow controlling elements ( 10 ) and an address decoder ( 40 ) for converting an address into selection signals for the memory cells ( 31 a, . . . ). The reconfigurable processing unit of the invention is characterized in that the address decoder ( 40 ) is shared between the configuration memory unit ( 30 ) and a further memory unit ( 20 ), or between two configuration memory units ( 30, 30 '). This provides for a reduction in memory area of the reconfigurable processing unit ( 1 ).
