    Szerintem a részben át-konfigurálható CPU/GPU-knak nagy jövője lesz.
    Akár az ARM vagy at AVX-512 kompatibilitásra is rá lehet segíteni ..

    "AMD made 20 claims in its patent application, but the gist is that a processor can include one or more execution units that can be programmed to handle different types of custom instruction sets. That's exactly what an FPGA does
    ...
    While AMD has made waves with its chiplet designs for Zen 2 and Zen 3 processors, that doesn't seem to be what's happening here. The programmable unit in AMD's FPGA patent actually shares registers with the processor's floating-point and integer execution units, which would be difficult, or at least very slow, if they're not on the same package. This kind of integration should make it easy for developers to weave these custom instructions into applications, and the CPU would just know to pass those onto the on-processor FPGA. Those programmable units can handle atypical data types, specifically FP16 (or half-precision) values used to speed up AI training and inference.

    In the case of multiple programmable units, each unit could be programmed with a different set of specialized instructions, so the processor could accelerate multiple instruction sets, and these programmable EUs can be reprogrammed on the fly. The idea is that when a processor loads a program, it also loads a bitfile that configures the programmable execution unit to speed up certain tasks. The CPU's own decode and dispatch unit could address the programmable unit, passing those custom instructions to be processed.

    persze az intel-nek is van valami hasonlója ... de ott nagy áttörés még nem volt ..

    Mottó: "A verseny jó!"
