Abstract


X processor is a stream-oriented applications , 64-bit high-performance microprocessors . It contains a plurality of memory components, such as of LRF , the CCRF and SRF etc. . The research subject for full-custom design of these storage components , combined with a variety of techniques to achieve a 32 - word 65 - bit read write register file , a 2048 - word 64-bit single-port SRAM in 0.13um process . The simulation results show that in the worst case : register file read and write operation time of less than 650ps SRAM read and write operation time of less than 1.4ns . The decoder is an important part of the critical path of the storage section , to improve decoding speed can effectively improve the reading and writing speed of the register file and SRAM . P-type dynamic circuit combined with static decoder , not only static decoder write overlap , but also improves the decoding speed . In addition, due to the special nature of the critical path of the decoder uses a technique called \SRAM decoding using these two technologies , and achieved good results . The good layout placement can effectively reduce the area, power, and delay of the circuit . Euler path method is the solution to a complementary CMOS circuit layout placement method, however , the Eulerian paths do not exist complementary CMOS circuit and a non-complementary CMOS circuit is powerless . In this paper, the basic Euler path method based on the proposed an expansion of the Euler path method , so that it can be applied to all complementary CMOS circuit and dynamic circuit layout layout . Register file and SRAM layout using the above method , effectively improve the layout to achieve the desired time .
