conditional branch การใช้

• At each conditional branch, both targets are added to the working set.
• A conditional skip followed by an unconditional branch performs a conditional branch.
• Conditional branches are done using a number of conditional skip instructions.
• Conditional branches act based on the value in the general-purpose register.
• There are two types of conditional branches : jumps to address and skips.
• Thus, it was not possible to include any conditional branch ( IF-THEN-ELSE ) logic.
• At first, the Mark I had no conditional branch instruction.
• On modern architectures this loop is inefficient due to a large number of conditional branches.
• Conditional branches ( BRxx ) can test an ALU flag and jump to specified address.
• An indirect branch can be useful to make a conditional branch, especially a multiway branch.
• Branch predictors are parts of a processor that guess the outcome of a conditional branch.
• The instruction set does not contain conditional branch instructions.
• Conditional branch instructions test the various flag status bits.
• This is an instruction that combines the effect of a conditional branch and a move instruction.
• Therefore the fetch of the target instruction of a conditional branch precedes evaluation of the branch condition.
• A conditional branch is even more problematic.
• Any bit of these bytes may be directly accessed by a variety of logical operations and conditional branches.
• Unconditional branches update the program counter with a new address computed in the same way as conditional branches.
• In all cases but conditional branch, the LINK field of the cell tells which instruction to execute next.
• Execution would then proceed with the multiplication and the conditional branch, which would evaluate to false and print OK.
