Abstract


Zheda number of core laboratory 32 embedded processor RISC32E of in order to enhance the performance of embedded processors , this article is based on the analysis of its performance and frequency of bottlenecks , structural framework proposed pipeline deepening Gemini and Gemini processor storage systems improved data prefetch mechanism to enhance the performance of the Gemini processor memory access . At the same time , the demand for low power consumption for embedded processors , the processor 's power consumption model for the exploration of the the Gemini power consumption evaluation method . The first single transmit processor memory accesses oriented division of Gemini pipeline . The experimental results show that the Gemini processors in standard cell technology under TSMC130nm worst case clocked at 360MHz typical case clocked at 500MHz EEMBC scores in ConsumerMark for the 0.11/MHz, the the 0.084/MHz compared to RISC32E processor increased 31.9 the %; TeleMark 0.02/MHz, the compared RISC32E the 0.0119/MHz 66.6% . Gemini processor hardware data prefetch memory access to improve processor performance . Using a prefetch stream buffer variable step smallest difference , by recording each occurrence Cache missing address , calculate the minimum difference and when the minimum difference matching data prefetch , the prefetch data to take into data Cache in . The Dhrystone the results of the evaluation show that the the Gemini processor hardware data prefetching mechanism can improve performance by 2.1% . Prefetch the EEMBC scores under in ConsumerMark review by the hardware data performance of a 3.3 % increase , a 3.7 % increase in TeleMark performance evaluation under . Finally comparative analysis of the different levels of processor power consumption model , such as system-level power consumption model , RTL gate-level power model , the transistor circuit level power model . RTL level power consumption - based model of the the Gemini processor power assessment .
