Abstract

Currently in order to increase the processor power, by taking advantage of true process-level-parallelism on a common workstation (i.e. Personal Computer or Laptop), you must replace the motherboard or the entire system to a multi-core platform. Unfortunately, as the demand for processor power increases the same expensive process of hardware upgrade has to be repeated. The solution would be to provide a dynamic and portable way of increasing/decreasing processing power through a common pluggable interface that is shared by most of workstations. A processor chip on a Universal Serial Bus (USB) card. The best example for such a solution would be low power consumption processor on a USB Flash Card (currently you might need a secondary power source). The ease of add/remove, common ports, operating system independent, and multiple number of USB ports on each system are the main advantages of such a approach.

USB Processor Power Card

Depending on the power requirements of the low power/voltage processor used, an additional power source may be required. For example, you can get 5 watts of power from using a dual USB connection (5V at 1A). If the processor operates within these conditions, and can stay cool without the need for a fan, then external power is not needed. Otherwise, the unit will require it's own power supply, similar to printers, external drives, etc. The operating system will recognize the new processor(s) via existing processor hot-swap technology. The operating system will also recognize that the processor is connected via USB 2.0 bus, and thus adjust its task scheduling accordingly. For example, high priority tasks are kept on-board, while low priority tasks are pushed to the USB connected processor.
