This is famous architecture by freescale. Initially it was developed by Apple - IBM - Motorola alliance in 1991. But now it is maintained by freescale (from Motorola) Power processors are specifically used in embedded system domain. Power architecture is specially used in ?
» Safety critical applications - aerospace, defense
» Industrial applications - controlling equipments etc
» Networking equipments - Ethernet switches, routers, wireless base stations etc
» Gaming system - Gaming console,.
Power processors are available up to the speed of 1.8 Ghz. Multi core chips are also available based on power architecture.
Power Cores…
QorIQ = based on e500 core, dual core or single core Ex: P1020
PowerQUICC= based on e600 core, use in communication domain
PowerQUICC I(MPC8xx) PowerQUICC II(MPC82xx)
PowerQUICC II Pro(MPC83xx) PowerQUICC III (MPC85xx)
Host Processors = based on e600 or e500 core MPC7xx, MPC7xxx, MPC6xx
Automotive Controllers = MPC5xx, MPC5xxx, freq 66 Mhz
FEATURES OF POWER ARCHITECTURE
· RISC processor
· speed up to 1.5 Ghz
· Support for SIMD ( AltiVec in terms of freescale) technology results in 128 bits vector operations
· Support for MMU ( Memory management unit), this means support of virtual memory concept in RTOS
· signal processing engine provide support for signal processing
· Enhanced energy management solution, new energy modes are added. These modes are JOG, packet lossless deep sleep mode
· support for high end buses like express PCI, VME etc
· multi core processor are also available like MPC8640D chip
