VIA Chooses Tensilica for Solid State Drive (SSD) Chip Design
Over 4x Higher Performance than Competing Processors
Taipei, TAIWAN and Santa Clara, CA, USA – February 15, 2012 -Tensilica, Inc. today announced that VIA has selected Tensilica’s Xtensa dataplane processors (DPUs) for a system-on-chip (SOC) design for solid state drives (SSDs). After conducting a technical evaluation, VIA determined that Tensilica’s DPUs provide over four times the performance of competing processors on key algorithms used to benchmark competitive alternatives.
SSDs require faster and more efficient data management and manipulation to increase their throughput (measured in Input/Output Operations per Second, or IOPS). With conventional processors, increasing the clock speed is the common way to increase performance. However, this increases energy consumption and die size, especially as speeds increase so much that designers are forced to move to more complex multi-core solutions.
Tensilica’s DPUs allow designers to customize the IP core, mix both control and signal processing, and add high-bandwidth connectivity to increase performance without increasing the clock speed. For example, designers can use single-cycle bit field manipulation and arithmetic instructions along with multiple simultaneous single-cycle table lookups to achieve over 10 times the efficiency of other processors. This not only increases IOPS, but also significantly reduces the energy consumed and the complexity of the SOC design itself.
“In the SSD market, every competitive advantage we can get is very important,” stated Jiin Lai, VIA’s CTO. “We have a significant advantage using Tensilica DPUs to lower the power and increase the throughput of our products.”
“VIA is a great example of how our customers benefit from high performance, low energy consumption, and small die size with Tensilica DPUs that have full software and hardware development paths which simplifies integration with existing RTL and software,” stated Steve Roddy, Tensilica’s vice president of marketing and business development.
This is all wonderful and great but by the time they make it to market you’ll have to buy a 1TB size SSD to see these outstanding gains in performance. Like the new Octane…great numbers no matter the data type with with consumer realistic queue depths of 1-4 but if you want to see it’s best performance you have to spend $900 or more for the 512GB drive. Someone, somewhere needs to figure out what it takes to maintain high performance in a reasonable size drive. Atm the SF2281 120gb drives are right on the edge with satisfactory performance without having the step to the 240GB hotrod. I’m hoping the soon to hit 24nm toggle doesn’t take too much of a random write hit (ie the 34nm to 25nm transition we all loved so well…NOT). Imo the Vertex 2 50GB 34nm drives were the last of the ‘poor mans raid’ era.
Seeing as the controller hasn’t yet been released, I wouldn’t jump the gun when it comes to performance vs capacity. VIA has been known to have one or two tricks up their sleeve and I wouldn’t be surprised if their SSD processor ends up exceeding everyone’s expectations. I’m sure we’ll find out soon enough.
based upon a MIPS processor, while heavily tweaked, will make for an interesting entrant. I am excited to see this, for some reason this announcement reminds me of when the Idilinx BareFoot controller was announced months before launch…. waited waited and waited…and on launch it was a giant leap forward.
Heres hoping my hunch is correct!
