2021年5月10日 · Whereas RISC-V simply provides branch instructions to compare two registers, MIPS relies on a comparison instruction that sets a register to 0 or 1 depending on whether the comparison is true. Programmers then follow that comparison instruction with a branch on equal to or not equal to zero depending on the desired outcome of the comparison.

2012年10月22日 · Yes. RISC is a wider concept. MIPS is RISC (Reduced Instruction Set Chip) architecture. Reduced (RISC) architectures tend to be simpler and have a small number of operations. Complex (CISC) architectures like x86 have more instructions, some of which take the place of a sequence of RISC instructions.

2010年4月14日 · MIPS is the cleanest successful RISC. PowerPC and (32-bit) ARM have so many extra instructions (even a few operating modes, 32-bit ARM especially) that you could almost call them CISC. SPARC has a few odd features and Itanium is composed entirely of odd features. The latter two are more dead than MIPS.

2022年7月13日 · ARM and RISC are used pretty much interchangably - Nope, RISC is a category that includes Instruction Set Architectures (ISAs) like ARM, PowerPC, MIPS, RISC-V, SPARC, 8-bit AVR, and others. ARM is one of the least RISCy, having a load-multiple instruction and complex addressing modes.

2022年4月26日 · Note: This question was originally titled/tagged risc-v, but the code can only assemble for MIPS, and the accepted answer is also only correct for MIPS. So lets just make it a MIPS question. MIPS uses 16-bit immediates for lui and all other immediate instructions, and zero-extends bitwise boolean immediates (ori/andi/xori). Other MIPS ...

2019年9月9日 · MIPS has 4 argument registers whereas RISC V has 8; MIPS uses separate return value and argument registers whereas RISC V uses shared return and argument registers. MIPS has 8 saved registers, whereas RISC V has 12; If there's parameter passing, it might require more rework especially if you want to follow the RISC V calling convention.

2022年11月28日 · However, the instruction set architectures for MIPS & RISC V specify only the instruction themselves, syscall and ecall. but do not say what they should do beyond making a request of the operating environment. Different operating environments, like linux, will provide different offerings than the MARS/RARS operating environments, as may ...

2019年7月4日 · SLR is a typo and should be SRL instead.SRA does an arithmetic shift and SRL does a logical one.So SRL will shift zeros in whereas SRA shifts the sign bit in.

At the hardware / machine-code level of ISA design, MIPS doesn't have a subi / subiu instruction. That makes sense because MIPS doesn't have a FLAGS register. There's no carry flag that would record the difference between adding a negative or subtracting a positive, like there is on many other architectures (x86, ARM, and many other less RISCy ...
