The address is ra+2. a4 will have the value of 0xSSSSXXa0 where XX is whatever value happens to be in the next byte and SSSS is the sign extension of it. If that byte was 0xef then a4 can indeed have the value 0xffffefa0. Share.

WebIn the last chapter, we showed that RISC-V base 32 bits instructions (RV32I) can be further divided into subgroups. We also showed that integer computation subset consists of 2 different datapaths, which are register and immediate. In this chapter, we will be building control transfer (or called “branch”) and load-and-store datapath of RV32I. WebIf the branch condition evaluates to false, the instruction-address-misaligned exception will not be raised.
