The Epiphany core is a co-processor, and the "main" processor is a couple of ARM cores to run Linux/other.
Maybe in the future they will offer boards with Risc-V main processors, and Epiphany co-processors.
I'm not sure how feasible 1024 Risc-V cores would be (although it sounds awesome). Epiphany cores were designed for this sort of thing.
- adapteva 10y agoAgree, but people have all kinds of pre-conceived notions about co-processors so let's clarify some things: e5 can't self-boot, doesn't have virtual memory management, and doesn't have hardware caching, but otherwise they are "real" cores. Each RISC core can run a lightweight runtime/scheduler/OS and be a host.
