Shadow Register Sets

a. Describe the use of shadow register sets.

b. How many shadow register sets are supported?

c. What instructions are used to move data between them? Floating Point Numbers.

We have heretofore focused on integers and characters, but many computing systems need to work with floating point numbers.

a. Describe how floating point numbers are represented in the standard IEEE Std 754-2008

b. What is a nan?

c. What is a subnormal number?

d. Describe the support in the NIOS-II system for IEEE Std 754-2008 floating point operations.

Special NIOS-II features and capabilities

a. Compare and contrast tightly coupled memory to cache memory.

b. What is a custom instruction? How would you use it?

c. Describe the difference between Supervisor and User mode.

When would you use this capability? Assembly Language Concepts.
