Android used to help varied architectures – ARM, x86, MIPS. Whereas x86 continues to be technically supported, the selection for smartphones, tablets and smartwatches is right down to solely ARM. Because of this whoever owns ARM has an outsized affect over the entire ecosystem. Now Qualcomm and Google have introduced that they’re engaged on another structure.
Chances are you’ll or might not have heard of RISC-V (pronounced “danger 5”). It’s an open-source instruction set for CPUs that has been gaining traction just lately. Its open-source nature implies that chipset designers don’t must pay royalties like they do with ARM. ARM additionally limits who can create customized CPU cores (that prices further).
Google and Qualcomm are beginning small – actually, the 2 firms are engaged on RISC-V based mostly Snapdragon Put on chipsets “that may energy next-generation Put on OS options”.
Android doesn’t but have official help for RISC-V, the instruction set is so new that some components of it are nonetheless in improvement and Google hasn’t selected the baseline options that can be required. However since Put on OS is predicated on Android, this needs to be a stepping stone for extra highly effective chipsets that can be utilized in telephones and tablets sooner or later.
Right here’s why RISC-V is an enormous deal. ARM fees firms like Qualcomm, Samsung, MediaTek and others to be used of their Cortex CPU designs. Some firms like Apple, Samsung and Qualcomm (generally) use CPUs they designed in-house, however that requires an costly “architectural license”.
Now RISC-V being open supply doesn’t imply that every one CPUs based mostly on it are open supply too. There are some, however Qualcomm can be designing its personal, placing its experience in creating environment friendly and performant chips. This can give Google (and the Android ecosystem as a complete) another platform – each as fallback and to make use of as leverage when negotiating costs with ARM.
Qualcomm tends to launch new Put on generations each couple of years – Put on 2100 in 2016, Put on 3100 in 2018, Put on 4100 in 2020 and most just lately W5 in 2022. So, W6 subsequent yr? It’s attainable, however the firm’s press launch ends with the imprecise “Business product launch of the RISC-V wearable based mostly resolution timing can be disclosed at a later date.”
PS. RISC-V has been round for just a few years now and has attracted loads of consideration from different firms too – large names like Bosch, Infineon, Nordic Semiconductor, NXP and Qualcomm joined forces to hurry up the event of RISC-V {hardware}. Others too, e.g. Western Digital designed RISC-V cores to make use of in its flash controllers the place beforehand it used licensed designs from ARM, Intel and others, which added price to the tens of millions of SSDs that it ships.
