The design of stream architecture cryptography processor bases on the need of cryptography applications for information security equipment and fuses the basic structure of stream architecture processors.The paper basically researches and designs stream memory system which is a bottleneck that affects the processor's performance.The system aims at memory characteristics of the dedicated cryptography processor and takes reconfigurable design to satisfy cryptography applications' flexible and efficient requirements on the processor's memory system.Meanwhile

the design combines hierarchical-distributed-banked memory、parallel stream access of channels and stream access dispatcher strategy together

which optimizes memory access efficiency of the system to improve the whole performance of the processor.Research results demonstrate that comparing with the memory design of typical cryptography processors

memory access efficiency of this design can be highly raised to 6 times.
