Chip zombie rises again
Resurrecting the SuperH Architecture (2015)
Old chip, new chaos: fans cheer a comeback while skeptics ask who asked for this
TLDR: Developers want to revive SuperH, an older processor design, as a cheap and more open way to run Linux and reduce dependence on hidden chips inside modern devices. Readers were split between cheering the freedom-first vision and roasting it as nostalgic engineering that may never escape hobby status.
A group of Linux tinkerers showed off a plan to bring back SuperH, an older chip design from Hitachi, arguing it could become a low-cost, more open alternative to the locked-down mystery chips buried inside modern gadgets. The basic pitch was simple enough for even non-chip nerds: if your laptop and devices are full of tiny processors quietly running important jobs, shouldn’t people be able to inspect and control those too? That idea got a lot of readers fired up, with the comment-section energy split between "finally, real open hardware" and "cool hobby, but who is this actually for?"
That’s where the drama kicked in. Supporters loved the almost punk-rock attitude of making Linux run on the bare minimum, with some cheering the notion that today’s devices are stuffed with pricey extras nobody really needs. Critics, though, were not buying the romance. Their hottest take: bringing a dead-ish chip family back from the grave sounds fun for conference slides, but turning it into something people use in the real world is a whole different beast. The jokes practically wrote themselves: readers compared the project to digging an old console out of the attic, while others riffed on the title with zombie-chip memes and “some architectures never die, they just lose maintainers.”
Still, even doubters seemed to respect the mission. The biggest reaction wasn’t just about this one chip—it was the broader anxiety that we own devices packed with invisible little computers we don’t really control. And in classic comment-thread fashion, what started as a niche hardware talk turned into a full-on argument about freedom, practicality, and whether nerd nostalgia is actually a roadmap
Key Points
- •An LWN article covered a LinuxCon Japan session about reviving Hitachi’s SuperH architecture for open hardware use.
- •The speakers said expired and expiring patents on key SuperH designs make the architecture a candidate for revival.
- •Their SuperH-based J2 core design was presented as suitable for synthesis in low-cost FPGAs or for bulk manufacturing.
- •Jeff Dionne argued that controlling hardware means considering the many embedded ARM and MIPS processors inside modern laptops, not just the main x86 CPU.
- •The article states that Linux can run on very minimal hardware, requiring a flat 32-bit address space, basic CPU registers, I/O and storage, a timer for interrupts, and GCC, without necessarily needing an MMU, FPU, cache, or SMP.
