摘　　要：本文介绍了面向嵌入式应用的片上系统芯片:腾跃-1的设计和实现技术.该芯片包括32位嵌入式RISC微处理器内核、通用存储器控制器、LCD控制器、片上总线和各种外围设备.微处理器内核采用自主设计的指令集体系结构.该芯片已经在中芯国际0.18μm工艺上通过验证,主频300MHz@1.8V,可以应用于信息安全领域的身份认证和数据加密等应用.本文最后对芯片的进行了性能评测.TengYue-1 is a microprocessor subsystem for embedded applications. Its heart is a 32-bit RISC microprocessor based on an instruction set architecture （ISA） designed by us. Through a WISHBONE compatible on-chip bus, the microprocessor, a universal memory controller,a LED controller and other peripheral I/Os formed the SOC.TengYue-1 has been implemented and verified in SMIC 0.18p.m CMOS technology, and the maximum clock frequency is 300MHz@ 1.8V. This paper presents the design and implementation of TengYue-1 .We used 9 ARM benchmarks to evaluate the performance of the microprocessor and the results showed that it met our goal. We also found a simple solution to the memory access conflict problem caused by the microprocessor core and the LED controller.
