Similar historic ISAs include +Cray YMP1, ETA-19, Cyber CDC 205. More recent is the NEC SX Aurora. +They are all proprietary systems: Libre-SOC's efforts are entirely +FOSSHW. + +Open Scalable Vector ISAs include MRISC32/64 (in early development) and +RISC-V RVV. Advocates of RISC-V have been discovering to their dismay +that RVV and RISC-V has fundamental issues that cannot be fixed. +Additionally, submission of ISA modifications requires RISCV Foundation +Membership which puts us under impossible conflict of interest with +Full Transparency Conditions not only with NLnet but also with +EU Auditing Requirements. By direct contrast OPF External RFC Submission +does not require Secrecy. ## What are significant technical challenges you expect to solve during the project, if any?
