TI loosens the leash a littleAugust 27, 2009
We’re used to speed bumps on this road; we’re not so used to spec bumps. Code guru Exophase has discovered some interesting revisions to the OMAP3530 data sheet, which seems to be giving us a little more head room in terms of clock speed than we had before. The Cortex-A8, known to us as a “600Mhz+” processor, is now being listed as “Up to 720MHz”. Also getting an on-paper boost is the DSP core, which has jumped from 430Mhz to 520Mhz. MWeston speculates:
The truth is that the chips all seem to do 720MHz for sure but TI only lists speeds they have tested so maybe they have finally qualified it at 720/520 now.
Or to re-phrase, the 700Mhz mark could now be considered “normal operating range”, rather than being a cheeky 100Mhz overclock. It’s like eating a guilt free hamburger, even though you would have eaten it anyway. The 520Mhz DSP figure is more interesting though, as it may push us further into HD decoding territory.
The hardware itself hasn’t changed, it should be said. The team doesn’t have to run out and replace their stock of 3530s (gasp!) or anything crazy like that. All this means is that we can squeeze more fun out of the existing hardware, without feeling too naughty. Hit the source link if you’re up for some scarily in-depth discussion.
