PicoBlaze Architecture Answer the following questions about the PicoBlaze Architecture: a. List all storage units and what kind of data they can store (data, instructions, addresses)? b. What is the address range (in hex) for the instruction PROM? c. How many cycles does an instruction consume? d. What is the purpose of NOP instruction? e. List all instructions that directly manipulate the call/return stack. f. How many clock cycles does instruction decode take? g. What is the purpose of the interrupt input? How can we disable interrupts? h. What flags does the test instruction affect? Does it affect the register contents? i. When we execute a call instruction, does the PicoBlaze save the register file contents? j. What is the difference between ADD and ADDCY instructions? Explain why we need two variants of ADD instruction? PicoBlaze Architecture Answer the following questions about the PicoBlaze Architecture: a.
