<p>In the past few years, two important trends have evolved that could change the shape of computing: multimedia applications and portable electronics. 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. </p> <p>The microprocessor needed for these devices is actually a merged general-purpose processor and digital-signal processor, with the power budget of the latter. </p> <p>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. </p> <p>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. </p>
