Freescale PowerPC MPC8641
The MPC8641 system-on-chip is a member of the Freescale's Power ArchitectureTM family of processors. The MPC8641D uses two high-performance superscalar e600 (G4) cores running at up to 1.5 GHz. The LinuxLink software distribution model enables the usage of the Freescale MPC8641 LinuxLink for development targeting all designs based on Freescale MPC8641 processor and its derivatives.
With an improved execution pipeline MPC8641 delivers better performance, higher level of integration providing also number of interfaces for internal and external communication.
The MPC8641D with system logic provides support for a number of target applications including:
Networking
- Linecard combined control and plane
- Shelf controller
- Service card
Wireless Infrastructure
- Control card for NodeB, BTS, WCDMA, 4G LTE, WiMax
- General purpose compute blade
Storage
Military
The MPC8641D supports flexible software implementations: symmetric multiprocessing (SMP) and Asymmetric multiprocessing.
Processor derivatives enabled:
The Freescale MPC8641 LinuxLink can be used as a starting point for Linux development for designs based on any of the processors from the PowerPC86xx family.
Reference boards/OEM boards enabled:
The Freescale MPC8641 LinuxLink can also be used as a starting point for Linux development for designs derived from the MPC8641D HPCN Argo Navis development platform.
Notes:
Complete peripheral support for Freescale MPC8641 derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
Processor Overview
Based on Freescale's 90 nm process technology, the MPC8641 is designed to deliver higher performance with lower power dissipation.
