VR4000是下一代 CMOS 微处理机,在工业上它首先采用64位工具.其结构使用称作超流水线的技术。VR4000采用0.8μm 的优质节距(fine pitch)CMOS 过程工艺制造,它大约有130万个晶体管。在50MHz 操作下实现50MHzIPS。VR4000包括一个64位整数处理部件,一个64位浮点处理部件,一个8K 字节指令超高速缓存器,一个8K 字节的数据超高速缓存器,若干个主-辅高速缓存控制部件和一个存储管理部件。它具有多种处理能力。设计者把重点放在优质节距 CMOS 过程工艺以及结构的设计上。 The VR4000 is the next generation of CMOS microprocessors, the first in the industry to use 64-bit tools, and its architecture uses what is known as super-pipelining. The VR4000 is manufactured in a 0.8μm fine pitch CMOS process and has approximately 1.3 million transistors. Achieve 50MHzIPS at 50MHz operation. The VR4000 includes a 64-bit integer processing unit, a 64-bit floating-point processing unit, an 8K-byte instruction cache, an 8K-byte data cache, a number of primary-secondary cache control components and a store Management components. It has a variety of processing power. Designers focus on high-quality pitch CMOS process technology and structure design.
