As nouns the difference between microprocessor and hyperthreading
is that microprocessor
is (computer hardware) the entire cpu of a computer on a single integrated circuit (chip) while hyperthreading
is (computing) a form of microprocessor parallelization where each physical processor is treated as two virtual processors.

- When the microprocessor decodes the JSR opcode, it stores the operand into the TEMP register and pushes the current contents of the PC ($00 0128) onto the stack.

- The scope of hyperthreading instructions is not covered in this book.
- There are some cases where hyperthreading actually degrades CPU performance, especially when CPU utilization is high.
