Why it issues: RISC V pioneer SiFive has gone by way of a number of iterations, however has now solidified a enterprise mannequin that primarily positions it as a direct competitor to Arm. If they’ll proceed to execute they are going to profit from a lot of the very wholesome RISC V momentum.
We not too long ago attended an analyst briefing with SiFive. We wrote about SiFive final 12 months, and had been pretty cautious in regards to the challenges they face. With the good thing about time and a deeper dive into their plans, we got here away from this newest assembly rather more within the firm than we had been.
SiFive is without doubt one of the main firms offering RISC V options. RISC V is an “open” various to the Arm or x86 instruction set architectures (ISA), which energy the mathematics inside processors. We’ve got already touched with reference to RISC V, it’s technically fascinating and has arrived at an excellent time with appreciable curiosity from the market.
SiFive is usually described because the “Purple Hat” of RISC V, the main firm in commercializing an open supply codebase. However it is a flawed description.
SiFive is usually described because the “Purple Hat” of RISC V, the main firm in commercializing an open supply codebase. However it is a flawed description. As a substitute, we must always begin to consider SiFive as primarily a direct competitor of Arm, a licensor of ISA mental property. They promote “blueprints” that different firms pay to repeat into their very own chip designs. This appears a bit counter-intuitive since RISC V is “free” and “open.”

The straightforward rationalization is that there’s a huge hole between having RISC V code and really making that right into a functioning chip – there are all types of add-ons, instruments and options wanted to bridge that hole, and SiFive, like Arm, makes cash by promoting these. The extra advanced rationalization is that RISC V is just not actually “open supply,” it’s higher considered an “open commonplace,” akin to Wi-Fi.
That is extra correct, but additionally complicated, therefore all of the citation marks across the phrase “open.” Suffice to say that constructing RISC V chips is just not straightforward and SiFive has positioned itself to unravel that downside.
In our protection, we might be forgiven for getting this all muddled up to now, SiFive has undergone a number of iterations to succeed in its present mannequin. Prior administration had pushed the corporate in a number of instructions together with promoting their very own chips. The brand new mannequin appears to be like rather more coherent and sustainable.
Basically, we expect RISC V appears to be like to be in pretty fine condition. It has received widespread adoption in China pushed partly by the low price of use and partly by geopolitical issues. And main world chip firms are all adopting RISC V, pushed in no small half by questions on Arm’s altering enterprise mannequin, and the truth that they’re suing one in all their largest clients, Qualcomm.
RISC V nonetheless faces quite a few challenges, not least the by-definition fragmented nature of its “open” roots. That being mentioned, it has gained actual traction in lots of markets together with IoT, industrial and embedded techniques. There’s an argument that RISC V has appreciable attraction in Edge AI inference (a large market to-be), and a non-zero likelihood that RISC V positive aspects an actual foothold within the information middle.
And naturally, the large automotive semis market that lies simply over the horizon is as open to RISC V as it’s to everybody else.
This could imply good enterprise for SiFive. As extra firms construct RISC V options, the attraction of working with an organization like SiFive is appreciable, particularly for non-semis firms constructing their very own chips.
We all know many firms, giant and small, chip designers and non-chip designers, working with SiFive to speed up their plans. In some future publish we are able to lay out the benefits of working with SiFive as a substitute of flying solo. Put merely, SiFive ought to develop with the RISC V market, and that market is rising properly.
SiFive has clients throughout business verticals and end-user markets which is vital as RISC V utilization continues to be very a lot in experimental mode.
On the very least, we expect the way forward for most giant chips will entail multi-ISA SoCs, with RISC V/SiFive cores sitting subsequent to Arm cores, and even subsequent to x86 cores. There’s one other, stronger case that holds that RISC V can find yourself turning into the dominant ISA in lots of main markets. We aren’t able to go there but, however we’re optimistic about RISC V’s prospects and that ought to profit SiFive, particularly if they’ll prolong their present execution monitor document.
