CS 2734 Computer Organization II

• Finish up numbers:
  • Conversion from base b to base a when a is a power of b or vice versa.
  • Uses of different representations.

• Introduction to Sparc architecture - a RISC (reduced instruction set computer) machine. RISC characteristics include:
  • Large number of registers.
  • Register windows.
  • Simple instruction set.
  • Most instructions executed in one cycle.
  • Load and store architecture.
• Sparc registers (see the table on page 44 of Paul):
  • g registers are the global registers.
  • o registers are for passing parameters to called functions.
  • l registers for local variables.
  • i registers for incoming function arguments.

• A look at a simple Sparc assembly language program:

  Download the Sparc program simplesparc.m and compile by making Makefile
