WebAug 12, 2024 · In CPUs with a FLAGS register (e.g. x86 and ARM), those ALU outputs actually go into a special register with named bits. You can look at an x86 manual for conditional-jump instructions to see how condition names like l (signed less-than) or b (unsigned below) map to those flags: signed conditions: jl (aka RISC-V blt) : Jump if less … WebBCC (short for " B ranch if C arry is C lear") is the mnemonic for a machine language instruction which branches, or "jumps", to the address specified if, and only if the carry flag is clear. If the carry flag is set when the CPU encounters a BCC instruction, the CPU will continue at the instruction following the BCC rather than taking the jump.

WebEach base integer instruction set is characterized by the width of the integer registers and the corresponding size of the user address space. There are two base integer variants, RV32I and RV64I, described in Chapters 2 and 3, which provide 32-bit or 64-bit user-level address spaces respectively. WebCode Example 6.28 shows the use of the branch if less than (BLT) instruction and Figure 6.25 shows the machine code for that instruction. The branch target address (BTA) is …

WebBMI only supports the Relative addressing mode, as shown in the table at right.In the assembler formats listed, nn is a one-byte (8-bit) relative address.
