| joeorc said: Wait a min, the Arm Cortex A5 is not just some sort of Co-processor, it is a full CPU, and Mark already went over this it handles background downloading. the Cortex A5 is not just a simple processor or something like that, here look for yourself. The Cortex-A5 in AMD’s future APUs will be a fully functional ARM processor and in theory it is possible to run full ARM applications on the processor (OS differences not withstanding), though at this point in time AMD hasn’t released the full details on how accessing the ARM processor will work. Even if AMD just intends to use ARM for TrustZone today, this opens the door to comprehensive native ARM code execution in the future if AMD wanted to go that way; but at the same time this could end up being as far as AMD ever goes. and as its shown there it can be used for more than just security, for instance the PSVita is Powered by a Quad Cortex A9 Cortex-A Series
The ARM Cortex™-A series of applications processors provide an entire range of solutions for devices hosting a rich OS platform and user applications ranging from ultra-low-cost handset through smartphones, mobile computing platforms, digital TV and set-top boxes through enterprise networking, printers and server solutions. The high-performance Cortex-A15, the scalable Cortex-A9, the market-proven Cortex-A8 processor, and the high-efficiency Cortex-A7 and Cortex-A5 processors all share the same architecture and therefore full application compatibility, that includes support for the traditional ARM, Thumb® and high performance and compact Thumb-2 instruction sets. The Cortex-A15 and Cortex-A7 both support an extension to the ARMv7A architecture that brings support for large physical address reach and hardware virtualization, as well as AMBA4 ACE coherency. Together, these enable big.LITTLE processing. http://www.arm.com/products/processors/cortex-a/cortex-a5.php Its just not a simple coprocessor remember the PSVita is powered by a quad cortex A9, well think the PS4 containing a cortex A5 was not chosen for a reason? |
I know what an ARM Cortex chip is. What I'm telling you is that in its current utilization, it is being used as a co-processor. You are not usnerstanding the difference in a CPU and a co-processor. A CPU is the central chip. Doesn't matter if it's AMD, Intel, ARM, or whatever. A Co-Processor is a secondary chip that handles tasks that overloaded from the CPU. This could be another AMD, Intel, ARM or whatever chip. But that's doesn't make it a second CPU because it is not the central chip. It is periphery. Doesn't matter what type of chip is, who made, what other products us it...it is being used a Co-Processor. This is a matter of terminology and usage. A CPU is only a "CPU" if it is the 'central processing unit'. Otherwise, it's just a processor. Or in this case, a co-processor which supports the operations of the central processing unit.
