摘要: |
针对多核日益严重的功耗问题,利用异步技术在低功耗方面的优势,结合数据触发结构设计并实现了一种嵌入式异构双核微处理器(ADTA-1)。该设计将异步设计应用于嵌入式多核微处理器中,并在芯片中对异步微处理器进行了测试,验证了异步电路在多核微处理器中的有效性和低功耗特性,为进一步设计和实现低功耗异步多核微处理器进行了有益的探索。 |

Abstract: |
In order to resolve the power problem, this paper presents the design and implementation of an embedded heterogeneous dual-core microprocessor (ADTA-1), taking advantage of the low power feature of asynchronous circuits and the Data Triggered Architecture. Through testing, the asynchronous microprocessor is validated with its low power feature in multicore microprocessor, which provides a useful trial for future design of low-power asynchronous multicore microprocessors. |
Keywords: asynchronous circuits low power multicore embedded microprocessor |
