A reduced instruction set computer, or RISC (/ r ɪ s k /), is a computer with a small, highly optimized set of instructions, rather than the more specialized set often found in other types of architecture, such as in a complex instruction set computer (CISC). The main distinguishing feature of RISC architecture is that the instruction set is optimized with a large number of registers and a

bits (XLEN-1)..7 are all equal. short The convention used with RISC-V is that the return address should be stored with the return address register ra which is x1. Say you got some C code with call like this: foobar(2, 3) RISC-V recycles jal and jalr to get unconditional 20-bit PC-relative jumps and unconditional register-based 12-bit jumps. Jumps just make the linkage register 0 so that no return address is saved. 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.

This week we'll be delving a bit deeper into the RISC-V linker to discuss linker relaxation, a concept so important it has greatly shaped the design of the RISC-V ISA. Linker relaxation is a mechanism for optimizing programs at link-time, as opposed to traditional program optimization which happens at Se hela listan på khann.tistory.com Se hela listan på blog.csdn.net A RISC-V hardware platform can contain one or more RISC-V-compatible processing cores to- gether with other non-RISC-V-compatible cores, xed-function accelerators, various physical mem- ory structures, I/O devices, and an interconnect structure to allow the components to communicate.
