This strikes me as a clever solution for allowing multiple conditions to be combined and tested with a single conditional branch at the end, and therefore consume only a single branch prediction slot. It gives you the results in ... WebAll conditional branch instructions may be implemented as brbs s,k or brbc s,k, where s is the bit number of the SREG flag bit. For example brbs 6, bitset would branch to label bitset, if the SREG T bit was set. To make your code more readable, the AVR assembler adds the following “alias” instructions.

WebConditional Branch instruction in AVR Microcontroller In terms of assembly language programming, the most important and fundamental aspect is the ability to control the flow of a program. If we are controlling program flow, it means that we instruct the microcontroller to jump from one address to another address in the program.

WebIn computer architecture, predication is a feature that provides an alternative to conditional transfer of control, as implemented by conditional branch machine instructions.Predication works by having conditional (predicated) non-branch instructions associated with a predicate, a Boolean value used by the instruction to …

WebConditional execution is a good choice in implementation of many auxiliary or bit-twiddling routines, such as sorting, list or tree manipulation, number to string conversion, sqrt or long division. We could add UART drivers and extracting bit fields in routers. Those have a high branch to non-branch ratio with somewhat high unpredictability too.
