Interview: Where does the Cortex-A35 fit in ARM's lineup?

2015-11-18
hello my name is Gary soon found her Authority we're arm techcon 2015 in California and I've met up with nandan from Armand and then nice to see you pleasure to meet you Gary get into us a bit about details a bit about what your role is armed so I am the I manage the entire cortex processor portfolio within the CPU management a product group and it's been actually a pleasure since I've been doing this from the arm 11 days or 11 / 11 years ago now we've got this full-fledged portfolio of cortex processors and a couple of interesting announcement this week and one of those announcements was the cortex a 35 ultra-low-power a 64-bit do tell us a bit about that absolutely so just to give a bit of history the cortex a5 and a7 processors that we introduced about 55 years ago were targeted at opening up this entry level smartphone market and they have been successful in fact over 2 billion new units have shipped anywhere from $25 phones up two hundred fifty dollar phones and this market is growing rapidly and which is where I think the cortex 835 comes in as the software stacks start going towards the next generation arm v88 architectures and more and more phones get built with it the entry level also tends to migrate but there are two common characteristics that they want they want the footprint to be small and the power to be ultra efficient and the cortex 835 delivers on both of those it delivers more performance substantially more performance than the cortex a7 which is today the benchmark processor and at the same time is more efficient while Philippe being able to run today is 32-bit code and 64 bit cold going into the future and it's also quite versatile because you can have the record core and then you can go down to maybe a single core and that would maybe be good for IOT applications indeed so if you look at it certainly it enables the next generation of entry-level phones which is where we think a lot of initial interest is going to be the footprint is such that it could be used in a lot of other embedded applications and it is designed so that you know even when it's running full tilt at a gigahertz it's still well under 100 milli watts of power but for a lot of these other applications you mentioned you could see configurations that only sip about 5 milliwatts or 10 milliwatts while be fully being able to run higher level operating systems and higher level applications so just to go over your whole product range you've got the cortex controllers at the very low end called as m0 very very low power yes then you up to the m7 and then we could kind of a little jump and you get the a35 in its smaller configurations and then from then onwards we go right up to the a the a 72 you've covered as the msgs servers through sensors through to servers indeed indeed and actually you make a very good point everything from a very small micro controller that last son you know years on battery or even energy harvested which is where the cortex and zeros come and at the upper end the product we launched at the tech con last year which of the cortex m7 really changes some of the microcontrollers at the high end and as you say also cortex 835 is in that range where it could run higher level operating systems but also change the microcontroller space or certainly the single board computing or industrial computing space and then be the effectively this launch pad for the higher end of the road map and of course it was pretty compatible course with your Molly graphics range of course and you had the Molly 470 released recently and that's also a low-energy processor as well and of course it's big.little compatible so it makes a very good little core in that configuration absolutely in fact what we talked about earlier cortex a53 was the little this is almost littler than the little and it certainly changes the dynamic range of the solutions you can offer combine that with the Molly 470 graphics you can think of very compact new devices that are very very capable of delivering very good visual interface very good interactive performance that's actually great well thanks very much my name for your time it's been a pleasure so Gary Simmons from arm techcon thanks very much thank you Gary
