who's who in the SSD ecosystem? - Cadence

by Zsolt Kerekes, editor - StorageSearch.com - - December 18, 2015

Although Cadence hasn't yet appeared in the Top SSD Companies (yet) Cadence is one of the leading supplier of processors used in SSD controllers.

The company's Tensilica processor has been used (with different customization options) in SSD controllers from - Seagate (SandForce range), Phison and ViaTek.

I was an electronics design manager before CAD became so easily accessible on workstations and my wife was the European marketing manager at a leading ASIC company before Cadence was founded (in 1988) so I've been generally aware of Cadence's role in the electronics systems design and integration business for some time.

But although I had noted Cadence being mentioned from time to time in past storage news stories it's the nature of the tool and glue chips industry that most such relationshops aren't discussed publicly - or (more often) are cloaked in secrecy.

As a result Cadence hasn't appeared much in these pages and has never appeared in the Top SSD Companies list (compiled by StorageSearch.com).

That's nothing to worry about. There are many companies which you don't hear about much which are - nevertheless - strategic suppliers inside the SSD ecosystem.

This anonymity (of talented SSD bit part players) used to be the same story with SSD controllers.

And after all's said and done - who cares about what processors are used inside SSDs?

It's what happens to them in the SSD design architecture and integration which counts. Right?

So although I was aware that Cadence is one of many processor and semiconductor IP companies which are used in the SSD market I never had any particular reason or interest in judging the magnitude of their activity and contributions.

That was until a recent conversation with Cadence about the SSD market in which I learned that Cadence - by its own reckoning - estimated that its Tensilica (processor) was used in more SSD brands than any other processor.

That wasn't what I expected.

So I fired straight back... Do you have any market report evidence or a web page which supports the claim that Tensilica processors that are in more brands of SSD than any other?

Cadence didn't have such a web page. But the details which they sent me by email (which I can't publish here) did confirm to my own satisfaction that their processor has been used by many noteworthy SSD companies (including several which have appeared in the Top 5 section of the Top SSD Companies).

When it comes to the publicly known SSD relationships...their processor has been used in several well known COTS SSD controller brands - which includes (among others) the SandForce controller from Seagate. So you could say - that helps the maths in their claim.

For reasons which I've discussed in earlier articles we're now entering a phase of the SSD market in which more new products need to be designed than have been done before. Which means that many of us will now have a vested interest in descending down to levels of detail in the SSD ecosystem which were previously hidden in the mists of design detail - deep inside the SSD.

Cadence mentions in SSD market history

In June 2010 - Cadence acquired the SSD controller and IP company - Denali Software.

In August 2010 - Cadence discussed the complexity of typical enterprise SSDs (pdf) in a white paper at FMS which also noted the theoretical performance bottlenecks of interfaces (SAS and NVMe PCIe ) in comparison to the available headroom in flash arrays when sized to maximally fit typical drive form factors.

In October 2011 - Cadence collaborated with BiTMICRO to set up a new micro-chip design training center in the Philippines - called the Bruce Institute of Technology.

In February 2016 - Cadence showed the ideas which it were important to SSD market thinking with its suggested set of links to articles for the SSD Bookmarks series.

Implementing XTS-AES for SSDs on Xtensa Processors
Editor:- February 5, 2016 - "An XTS-AES engine based on the Xtensa processor can provide performance that rivals most hardware solutions, but retains the ease of design and flexibility found in software based solutions."

That's the summary of a paper - Implementing the XTS-AES Standard on Xtensa Processors (pdf) - which is one of several resources recommended in a new set of the SSD Bookmarks today on StorageSearch.com

The new set of bookmarks were suggested by Neil Robinson who is Product Marketing Director, Tensilica Processor IP, Cadence. ...read the article

When Samsung decided to add a PCIe interface to its SSD controllers in eary 2012 it needed hundreds of times greater performance to validate the design than its previous simulation environment could provide.

Using Cadence PCIe AVIP running on the Palladium XP platform, Samsung was able to close this gap and reach the speed and productivity goals they had established for SSD validation and Samsung said they would use it on future SSD design projects.
