### Instruction: What are some examples of CPU architectures that do not use a dedicated flag register?
### Input: Some CPU architectures, such as the MIPS and Alpha, do not use a dedicated flag register. Others do not implicitly set and/or read flags. Such machines either do not pass implicit status information between instructions at all, or they pass it in an explicitly selected general purpose register.
### Response: Some examples of CPU architectures that do not use a dedicated flag register include MIPS and Alpha.
