Powerpc芯片优势
Myth 1:Price
§PowerQUICC™ processors§On-chip I/O lowers system-level BOM cost à fewer bridge chips needed
–Ethernet and memory controllers, security hardware acceleration
–Popular I/O interfaces: USB, PCI, PCI-ex, SATA
Myth 2: power consumption
§PowerQUICC maximum power ranges from <2 to <8 watts
–Devices can run without fans from -40C to Tj=105C
§Performance does not change as temperature increases
Myth 3: The architecture I have is ok - architecture does not matter
§Power Architecture delivers best-in-class system performance
–More performance/MHz, /watt and /$
–value-added integration provides additional cost and power savings
–Longer product life cycles (normally 10 to 15+ years)
Why Customers said they chose Freescale PowerQUICC
(1)MIPS/MHz performance
§“The reason the Power Architecture was chosen was because its MIPS per MHz is higher than Renesas SH and ARM. In comparison the ARM is about 1.1 MIPS/MHz, SH4A is about 1.8MIPS/MHz, and Power Architecture is > 2.0MIPS/MHz.”
(2)MIPS/watt
§“We needed certain performance within the 2W power envelope, reliability, long life time were important to us.”
(3)Additional comments
§SW migration/re-use ability from low-end to high-end devices
§Combination of integrated functionality: Ethernet, USB, PCI
§All protocols in HW: Ethernet, ATM, IPsec, security, HW acceleration
–Shrink-wrapped microcode means faster time to market and fewer hassles
§Robust and industrial strength for harsh conditions
