e6500: Freescale's Low-Power, High-Performance Multithreaded Embedded Processor
David Burgess, Edmund Gieske, James Holt, Thomas Hoy, Gary Whisenhunt · IEEE Micro · 2012
Freescale's e6500 targets highly efficient scalable embedded processing. It incorporates many architectural and microarchitectural performance innovations, from advanced virtualization technologies and judicious hardware thread resource allocation to coherency and interconnect transaction avoidance techniques, including decorated storage operations, lightweight ordering barriers, and cache stashing. Power-efficiency techniques, including cascading system power management and automatic execution unit powering, are coupled with a power-optimized physical design.
