MPC8641D Dual Core Processor
Freescale has leveraged its expertise in building high-performance PowerPCâ„¢ processors and highly integrated communications processors to design the MPC8641D Dual Core Processor. This processor integrates two e600 PowerPC cores, two memory controllers, Ethernet controllers, a RapidIOâ„¢ fabric interface, a PCI Express I/O interface, and a high performance MPX bus that scales to 667 MHz. It's one powerful processor, but it doesn't break the power budget starting at 15 Watts.
The MPC8641D supports flexible software implementations: symmetric multiprocessing (SMP) and Asymmetric multiprocessing. With SMP, one operating system runs on both cores, but from a programming perspective, it appears that the developer is writing a program for a single core. With Asymmetric multiprocessing, two instances of the same operating system or two entirely separate operating systems can be run on the two cores, largely unaware of each other.
@bbrv:
This processor is AWESOME! You should seriously consider using it in your next Pegasos board: ddr2 controllers (on the processor!) and PCI-Express I/O interface and 50% MIPS/Mhz increase! Without breaking 15W!
The 7448 could substitute the G3: with its ~10W at 1.4Ghz it could easily run without dissipator at slightly lower frequencies...
And read about asymmetric multiprocessoring... Two OSs running at the same time!
