Branch processor

The branch processor instructions include the branch instructions, Condition Register field and logical instructions.

The branch processor has three 32-bit registers that are related to nonprivileged instructions:

• Condition Register
• Link Register
• Count Register

These registers are 32-bit registers. The PowerPC® architecture supports both 32- and 64-bit implementations.

For both POWER® family and PowerPC®, the branch processor instructions include the branch instructions, Condition Register field and logical instructions, and the system call instructions for PowerPC® or the supervisor linkage instructions for POWER® family.
