移动电话和PDA(个人数字助理)等手持设备的成功主要得益于移动处理器的节能设计。这导致了与PC相比缺乏可执行的功能。然而，近年来手持设备的趋势是为多媒体处理添加复杂的功能。由于这种方案依赖于软件方法，因此很难在低功耗的情况下实现高速。基于1GIPS(10/sup 9/指令/秒)和1W功耗的巨大吞吐量，为了满足对功耗、速度和可用性的需求，我们开发了一个名为GRAILLA的Java嵌入式移动处理器内核。介绍了一种采用0.35/SPL Mu/m标准单元工艺的大猩猩衍生品的设计方法。
Handheld devices, like cellular phones and PDA (personal digital assistants), have succeeded mainly through the power conscious design of mobile processors. This has resulted in a lack of performable features compared with PCs. Yet, the trend of handheld devices in recent years has been to add sophisticated functions for multimedia processing. Since such a scheme has relied on a software approach, it is hard to achieve high speed with low power. Setting up the drastic throughput of 1 GIPS (10/sup 9/ instructions/sec) and 1 W power dissipation to meet the demand for power, speed, and usability, we have developed a Java-embedded mobile processor core named gorilla. This paper focuses on the design approach to one of gorilla's derivatives using 0.35 /spl mu/m CMOS standard cell technology.
