Future of MIPS / PIC32

I have a lot of legacy designs with the PIC32, but given the sale of Imagination, should I start to bite the bullet and transition future work to Microchip's ARM-based processors?
 
I fully expect Microchip to support the PIC32 for a long time, but should we expect Microchip to invest most of its future effort on ARM?
 
Just wondering if anyone has any insight on this.

    The most you'll get here is speculation. If anyone actually knows, they can't talk about it in public.

    Understood.  However, in the absence of clear guidance from Microchip, it seems the prudent course is to begin to migrate skills and designs toward ARM.

    As someone on the "inside", one of the things to keep in mind is that Microchip doesn't End-of-Life products. I expect that we will still sell MIPS-based PIC32 devices for the foreseeable future, in addition to ARM-based parts.

    To someone on the "outside" (like me), this sentence sounds a lot like a confirmation that PIC32s are getting phased out in favour of SAMs (which in turn are being renamed to PIC32CZ).

    We will Find out when the start shipping Chips. The Price/ Performance will tell.

    That would be a horrid kind of renaming, exactly the kind of thing that causes confusion amongst potential customers, where only the marketing people know which combination of numbers and letters refers to specific attributes of the product and even then they have to look it up.

    Well, seems MIPs is dead/will be dead soon.
    I guess thats why Microchip got Atmel...

    Well, since that article was written MIPS has been tentatively acquired by a US organisation so that Imagination can be sold to Canyon Bridge, whose takeover of Lattice Semi was thwarted by the US authorities on the grounds that they are supposedly too close to Chinese state interests. So, MIPS gets separated from Imagination and what might be regarded as its PowerVR-led strategic priorities.
     
    It is true that ARM products are everywhere and are very competitive. Then again, you see companies like Mediatek acquiring Ralink whose products are MIPS-based, and the architecture certainly has its niches.
     
    In the longer term, I think RISC-V may have an impact: it has similar heritage to MIPS and seeks to rectify the various deficiencies of the MIPS architecture that the designers have tried to rectify in the past with things like DLX and OpenRISC. There are already RISC-V microcontroller products, and we may see RISC-V cores appear in other products, just like OpenRISC cores have done. And with RISC-V people have been a lot more systematic about tool and system support, which is what apparently did it for OpenRISC.
     
    Of course, the instruction set architecture is just one aspect of a microcontroller, but I can easily imagine Microchip picking up RISC-V if MIPS isn't going anywhere in the longer term.

    That article is outdated. ImgTec sold the MIPS business to a company called Tallwood MIPS Inc. I have no idea about Microchip's licensing agreements, but I believe eg. the "Warrior" core used in the PIC32MZEF scales up to 2GHz, which would certainly cover their needs for a while. IMO it pretty much depends on where they want to spend their money.

    Microchip had the option to use ARM when they moved to 32 bit. They chose MIPS.

    Microchip had the option to use ARM when they moved to 32 bit. They chose MIPS.

    And that's the reason Microchip is still on my radar. MZ EF (or rather, the M-class core) is quite unique.
    How else would the evolution be kept if everybody jumped on the hyped ARM bandwagon?
     
    Now, if Microchip had more technical talent to provide better peripherals, and much less buggy, too, they could've had more edge.

    This personal opinion comes from someone who used to deal with ARM cores way before they became juggernaut. And let's be honest and acknowledge that it's not technical merits that made them one, but purely business strategy.
