In the first part of our series on ARMwe mentioned that with every major xeynos design ARM tries to choose 3 licensees to get early access to technology.

Samsung was first on the mobile market exynoos a Cortex A15 based SoC: Featuring two cores running at up to 1. The next logical step would be a quad-core version, which we sort of got with the Exynos – or as it’s more commonly known: The specific implementation of big.

They’re either all on or all off. This is by 54110 the easiest to implement from a software perspective, but is obviously the less interesting option from a heterogeneous SMP perspective. The Exynos saw limited use, appearing in some international versions of the Galaxy S 4 and nothing else.

Part of the problem with the design was a broken implementation of the CCI coherent bus interface that connect the two CPU islands to the rest of the SoC. In the case of thethe bus was functional but coherency was broken and manually disabled on the Galaxy S 4.

The implications are serious from a power consumption and performance standpoint. With all caches being flushed out to main memory upon a switch between CPU islands. Neither ARM nor Samsung LSI will talk about the bug publicly, and Samsung didn’t fess up to the problem at first either – leaving end users to discover it on their own.

Last week Samsung teased a new, improved Exynos 5 Octa – the Exynos Today we got the first details of the new SoC. The base CPU architecture remains unchanged.

Samsung outfitted the Exynos with four A15s 5401 four A7s, presumably exybos the same Cluster Migration big. Clock speeds on both clusters are a bit higher now, 1.

Note that on the Cortex A15 side this exceeds where even ARM recommends clocking Cortex A15 for smartphones as far as power efficiency eexynos concerned, but it should be fine for tablets. There’s no word on whether or not the CCI bug has been fixed, but I can only assume that it has been otherwise it’d be senseless to do another Exynos 5 Octa release this close to the original.

It looks like the CCI bug has been fixed. A six-core configuration is a bit odd in that we’ve never seen one before, but the T is scalable from 4 – 8 cores so it’s a valid config. On the memory interface front the Exynos retains a dual-channel LPDDR3 interface 2 x bit with 54110 for up to MHz memory, resulting in peak theoretical memory bandwidth of The biggest question about the new Exynos is whether or not the cache coherency issues have been worked out.

The solution remains a bit on the large side for most price sensitive tablets, but it could make for an interesting use case in a wxynos tablet.

In smartphones I’m still not sold on the idea of having four Cortex Sxynos running at up to 1.

If Samsung were to enable one of the more interesting big. Post Your Comment Please log in or sign up to comment.
