Sau khi Sun cho ra đời SPARCstation, các hãng khác cũng vội vã hoàn thành các hệ thống dựa trên RISC của mình. Thậm chí ngày nay thế giới của các mainframe cũng hoàn toàn dựa trên RISC. http://llvm.org/devmtg/2018-10/—LLVM backend development by example (RISC-V) - Alex BradburySlides: —This tutorial steps through how to develop an LLVM back RISC är en akronym för Reduced Instruction Set Computing (alternativt Load-Store arkitektur som är ett mer korrekt namn). RISC-principerna utvecklades av IBMs Watson Research Center mellan 1975 och 1979 när den första RISC-processorn med namnet 801 levererades. RISC-V, the open source fifth Berkeley RISC ISA, with 64- or 128-bit address spaces, and the integer core extended with floating point, atomics and vector processing, and designed to be extended with instructions for networking, I/O, and data processing.

RISC-V also recycles jalr to return from a subroutine: To do this, jalr's base register is set to be the linkage register saved by jal or jalr. RISC-V Reference Card V0.1 Registers Register ABI Name Description Saver x0 zero Zero constant — x1 ra Return address Caller x2 sp Stack pointer — x3 gp Global pointer — x4 tp Thread pointer Callee x5 t0-t2 Temporaries Caller x8 s0 / fp Saved / frame pointer Callee x9 s1 Saved register Callee x10-x11 a0-a1 Fn args/return values Caller The standard RISC-V ABI (a software convention, nothing to do with hardware) specifies that for normal functions rd should be register 1 (x1), which is then commonly known as ra (Return Address). Register 5 (x5) is also commonly used for special runtime library functions, such as special functions to save and restore registers at the start and end of functions. Registers are the most important part of any processor. RISC-V defines various types, depending on which extensions are included: The general registers (with the program counter), control registers, floating point registers (F extension), and vector registers (V extension).

Recently, I needed to analyze some RISC-V assembly code for a research project and then calculate some basic metrics, but I couldn't find a suitable tool. Ok, I'll just grab a parser from one of the smaller open-source assemblers.

Now the calculation is easy. 5-bits to represent registers, which means total number of registers is 2^5 = 32 registers With this in mind, you may think it’s odd that we’re using the zero register, which RISC-V assemblers interpret as the x0 register, as our destination register, since this effectively creates an unconditional and side-effect free jump to offset_address.

RISC-V is an open-source speci2ication for computer processor architectures, not a particular chip or implementation. 2017-08-14 · Before we can board the RISC-V train, we'll have to take a stop at the metaphorical ticket office: our machine-specific GCC command-line arguments. These arguments all begin with -m, and are all specific to the RISC-V architecture port. In general, we've tried to match existing conventions for these arguments, but like pretty much everything else there are enough quirks to warrant a blog post it is the preset return register for RISC V lw ra 12 sp addi sp sp 16 dealocate from ECE 395 at New Jersey Institute Of Technology 2017-08-28 · Last week's blog entry discussed relocations and how they apply to the RISC-V toolchain.

Registers are the most important part of any processor. RISC-V defines various types, depending on which extensions are included: The general registers (with the program counter), control registers, floating point registers (F extension), and vector registers (V extension). Each CSR is assigned a DWARF register number corresponding to its CSR number given in Volume II: Privileged Architecture of The RISC-V Instruction Set Manual plus 4096. Linux-specific ABI This section of the RISC-V ELF psABI specification only applies to Linux-based systems.
