...Scheduler for in-order processors - what's present and what's missing in LLVM[3] by Javed Absar * Writing Great Machine Schedulers[4] by Javed Absar and Florian Hahn Hi Alex, Please leading me to implement Machine scheduling model for at least one core (e.g. Rocket, PULP)[5] Rocket - RV64G - "in-order", single-issue applicaEon core, BOOM - RV64G - "out-of-order", superscalar applicaEon core[6] So what about PULP? is it in-order or out-of-order? Hi LLVM developers, Welcome to review our work about porting GlobalISel to RISCV[7] and give us some suggestion, th...

...resentations. The standard is structured to allow implementers to choose appropriate subsets to support, for instance a micro-controller might support 'RV32I' (32-bit RISC-V with the integer instructions) and an application core running Linux might implement RV64IMAFD (commonly shortened to RV64G: 64-bit with integer instructions, the multiply extension, atomics, and single and double precision floating point). A generous portion of the opcode space is left reserved for implementers or researchers to add their own instructions. In line with the proposed policy for adding a new target (http...
