ARM based multicore systems generally use CMN-400/500/600/700 IP (from ARM) as the processor interconnect. https://developer.arm.com/Processors/CoreLink%20CMN-600 And all those 8 and 16-bit processors are single core, so your statement above, which references "no matter how many cores" doesn't apply to them. >>mesh/ring structures into the I/O side (e.g. one host bridge per >>PCI Express root port, one or more for on-chip accelerators, etc). >Thats nice, but CPU > x86. What does that mean? Every major multicore processor currently shipping (including Apple M7+) operate as described above. Including most mid-range and high-end application specific system-on-chips (SoC), including those using the ARM architecture. The proceedings from https://hotchips.org/ over the last two decades describe the state of the art. |

Swapping is for stability and not for performance. No one considers running applications actually swapping. > What was it intended for then given it was written in basic C? You didn't write that on a Z-80. |
