Branch instruction needs to change the pc for next instruction address based Instruction memory must be separated from data (separate datapath resources).

RISC-V: building a datapath for conditional Branch instructions. Ask Question Asked 1 year, 8 months ago. Active 1 year, 8 months ago. Viewed 642 times 0 \$\begingroup\$ I am simulating a multi-cycle 32bit RISC-V CPU in Logisim-Evolution and so far so good, i had implemented almost every instruction from the basic RV32I ISA. But im having Home > SD-Branch > SD-Branch > show datapath bwm table Description This command displays a table of all configured bandwidth contracts and the bandwidth management table entry statistics. COMP 273 13 - MIPS datapath and control 1 Feb. 22, 2016 Data path for bne Next let’s look at the case that the current instruction is a conditional branch, for example, bne $s0 $s2; label which is also I format.

see Figure 5.10: The datapath for a branch uses an ALU for evaluation of the branch condition and a separate adder for computing the branch target as the sum of the incremented PC and the sign-extended lower 16 bits of the instruction (the branch displacement), shifted left 2 bits. RISC-V Conditional Branch Datapath All branch instruction uses B-type format. 12 bits imm subfield has its 0th bit set to 0, which means its value is always multiple of 2 bytes (calculate it yourself if you want to see). The offset then sign-extended to 32 bits and added … The branch datapath (jump is an unconditional branch) uses instructions such as beq $t1, $t2, offset, where offset is a 16-bit offset for computing the branch target address via PC-relative addressing. The beq instruction reads from registers $t1 and $t2, then compares the data obtained from these registers to see if they are equal.
