In this paper computing environment as a worthy new direction for computer architecture research: personal mobile computing, where portable devices are used for visual computing and per-sonal communications tasks. Such a device supports in an integrated fashion all the functions provided to-day by a portable computer, a cellular phone, a digital camera and a video game. The requirements placed on the processor in this environment are energy efficiency, high performance for multimedia and DSP functions, and area efficient, scalable designs. Together, these trends will lead to a personal mobile-computing environment, a small device carried all the time that incorporates the functions of the pager, cellular phone, laptop computer, PDA, digital camera, and video game. The microprocessor needed for these devices is actually a merged general-purpose processor and digital-signal processor, with the power budget of the latter. The microprocessor needed for these devices is actually a merged general-purpose processor and digital-signal processor, with the power budget of the latter. Yet for almost two decades, architecture research has focused on desktop or server machines. We are designing processors of the future with a heavy bias toward the past. To design successful processor architectures for the future, we first need to explore future applications and match their requirements in a scalable, cost-effective way. The authors describe Vector IRAM, an initial approach in this direction, and challenge others in the very successful computer architecture community to investigate architectures with a heavy bias for the future. We examine the architectures that were recently pro-posed for billion transistor microprocessors. While they are very promising for the stationary desktop and server workloads, we discover that most of them are un-able to meet the challenges of the new environment and provide the necessary enhancements for multimedia ap-plications running on portable devices. We conclude with Vector IRAM, an initial example of a microprocessor architecture and implementation that matches the new environment.
