Memory Maps of ATMega328

Construct a memory map for both ATMega328 and the Intel Xeon (E7 v3 family). Include hexadecimal addresses to denote memory locations and clearly indicate the name for each section of memory (i.e. General Purpose Registers, Special Purpose Registers, RAM, etc.).

Include the following discussion with the assignment:

• Similarities and differences in the structure of the memory map
• Comparison of cost per Kbyte

Considerations in writing code targeted at each processor in terms of memory usage

Discussion: RISC vs. CISC

Discuss differences in RISC and CISC architecture processors in terms of memory organization and addressing. Provide specific examples of both RISC and CISC processor types.

QUESTION 1

When a program routine constantly looks a certain condition and executes a command when the condition is met, this is called:
