Something similar happened to Slovene Iskra Triglav computer which was quite advanced for the time (capable of running three different CPUs) but then caught in between US-Soviet cold war/embargo while trying to sell them to Soviet Union.
Three CPUs with different architectures on one device sounds crazy. That's amazing.
PS3 comes to mind
Though in embedded, thats fairly normal.
I've got a $1 linux embedded SoC that has a 64 bit riscv core, a 32 bit riscv core for running realtime stuff and a low power embedded 6502 on it too because why not.
Original Nintendo DS had two different ARM CPUs for DS games and the same CPU the GBA had for direct compatibility.
The second CPU is the GBA CPU, but at twice the clockspeed (which can then downclock for GBA games). You're double-counting it and making it sound like the system had three.
The 3DS is the real funny one, adding its own new CPU alongside both the DS and GBA CPUs. So that's actually three.
Yeah, RP2350 in Raspberry Pi Pico 2 also has 2 ARM cores and 2 RISC-V cores.
Which reminds me, I purchased one a month ago to play around with as it has good documentation, yet I haven't used it once so far.
Its actually not seperate cores, they're RISCV or ARM, based on a switch. MilkV does that too with one of its chips. They're mostly the same architecturally, theres something like 10% that gets enabled/disabled with each ISA selection.
But you can still run both at once. RP2350 datasheet
From section 3.9 Arm/RISC-V architecture switching:
From section 3.9.2. Mixed architecture combinations:
My point it isn't 2x arm and 2x riscv. They recycle most of the silicon used.
Cool, which SoC?
SG2002/SG2000 and the CV1800B chips by MilkV
Thank you!
6502 to play C64 games of course.
OSX (now MacOS) was built and running on PowerPC and Intel for years before Intel Macs were released. I assume the same was true before they released the Apple silicon chips.
Yeah but they weren't running both in the same device at the same time.
PPC -> Intel they just recompiled their OS and fixed it up for the x86 platform, then the same for Intel -> ARM
They did not have a laptop with an x86 processor and a PPC at the same time.. though there are some hillariously bespoke accellerator cards from back in the day to do all sorts of strange things.
That said, laptops are full of microcontrollers with firmware, lots of those will be atmega, st32, 6502 and the like. Things like a WLAN or WAN card will be a little ARM soc of some flavour.
So it really depends on where you draw the line. If its executing the main workload, I'd say thats the CPU, everything else is a microcontroller enabling it to do that
Haha look at this dumbass, he thinks being stupid is aspirational.
Low effort. Try harder.
Hope he keeps going, I want to see how many he has...
Soviets did a lot to harm Eastern Block tech. Bulgarian Pravetz was a clone of Apple ][. Nothing impressive but cheap, functional, domestically produced. Can't really be exported towards west due to blatant IP violations, but the production capabilities were good enough to produce and export hard drives.
Except the trade deal with Britain was blocked by Soviets because it was seen as a security threat, and an industry died in its infancy.
There's another future where Yugoslavia is the birthplace of a free software movement, and homebuilt PCs lower the barrier of entry to anybody with some time on their hands, with software distributed by radio and powerline until the advent of internet.
Ah yes, I recently learned about Galaksija, it's fascinating!
yugoslav.
slovenia wasn't a country back then
Iskra Delta was a Slovene (republic) company, even within Yugoslavia. But if you nitpick, then technically it would be Yugoslavia as country.
The Socialist Republic of Slovenia was one of the six federal republics forming the Socialist Federal Republic of Yugoslavia, if you want to be technical about it.
that computer sounds awesome, imagine something like this existed today(like a computer with a RISC-V,Arm64 and X86-64 CPU) .
