Description: Jump displacement refers to the distance from the current instruction to the target instruction in a jump. In the RISC-V architecture, this concept is fundamental for executing jump instructions, which allow a program to change its execution flow non-sequentially. The displacement is generally expressed in terms of bytes and is calculated relative to the address of the instruction being executed. This means that the displacement is used to determine how many positions the program counter must move to reach the desired instruction. In RISC-V, jump instructions can be relative, meaning that the displacement is calculated from the current instruction’s address, allowing for greater flexibility and efficiency in programming. This approach also helps reduce code size, as less space is needed to store jump instructions compared to absolute addresses. Additionally, the use of relative displacements facilitates code relocation, which is especially useful in various execution environments where code may be loaded at different memory addresses. In summary, jump displacement is a key component in the RISC-V architecture that enables efficient control flow implementation in programs.
