本論文有兩大主題:FlexRay車載網路通信系統實體層設計與高速32位元樹狀架構之進位前瞻式加法器兩大部分。
第一部分介紹FlexRay車載網路通信系統之系統規範,以及將FlexRay車載網路通信系統之實體層部分以單一個系統單晶片予以實現。
第二部分利用我們提出互補式全N電晶體(Complement All-N-Transistor, CANT)架構,並組成一個樹狀架構之前瞻進位式加法器。我們利用動態偏壓的方式加快反相動態電路轉態速度,使得反相與非反相電路的運作速度極為相近。本加法器架構具有容易擴充資料架構之優點,且以UMC 90 nm製程設計與實現,本晶片工作時脈速度可達7.2 GHz。
This thesis comprises two parts : the first one is the design and implementation of FlexRay automotive communication system physical layer; the second part is the design of a high speed pipelined tree-structured carry lookahead adder (CLA).
The first part of this thesis is to introduce the physical layer specification of FlexRay automotive communication system. Then, it is realized in an SOC by a typical 0.18 um CMOS process.
The second topic is to propose a novel CANT logic. By the CANT logic, a pipelined tree-structured carry lookahead adder is designed and implemented. The dynamic bulk biasing technique is utilized to increase the switching speed of inverting circuits such that the delays of the inverting and non-inverting circuit is very close. The proposed architecture can be easily expanded to long data words CLA. Post-layout simulations reveal that the 32-bit CLA using the proposed CANT logic can operate up to 7.2 GHz by using the UMC 90 nm process.
