  • Machine Instructions and Programs
    Hamacher-38086 book June 28, 2001 11:31 CHAPTER 2 MACHINE INSTRUCTIONS AND PROGRAMS CHAPTER OBJECTIVES In this chapter you will learn about: • Machine instructions and program execution, including branching and subroutine call and return operations • Number representation and addition/subtraction in the 2’s-complement system • Addressing methods for accessing register and memory operands • Assembly language for representing machine instructions, data, and programs • Program-controlled Input/Output operations • Operations on stack, queue, list, linked-list, and array data structures 25 Hamacher-38086 book June 28, 2001 11:31 26 CHAPTER 2 • MACHINE INSTRUCTIONS AND PROGRAMS This chapter considers the way programs are executed in a computer from the ma- chine instruction set viewpoint. Chapter 1 introduced the general concept that both program instructions and data operands are stored in the memory. In this chapter, we study the ways in which sequences of instructions are brought from the memory into the processor and executed to perform a given task. The addressing methods com- monly used for accessing operands in memory locations and processor registers are presented. The emphasis here is on basic concepts. We use a generic style to describe ma- chine instructions and operand addressing methods that are typical of those found in commercial processors. A sufficient number of instructions and addressing methods are introduced to enable us to present complete, realistic programs for simple tasks. These generic programs are specified at the assembly language level. In assembly lan- guage, machine instructions and operand addressing information are represented by symbolic names. A complete instruction set is often referred to as the instruction set architecture (ISA) of a processor.

  • Large and Fast: Exploiting Memory Hierarchy Two Kinds of TLB Misses
    Chapter 5C Large and Fast: Exploiting Memory Hierarchy Two kinds of TLB Misses Check the valid bit of a page table entry If it is on, the page is in memory (a simple TLB miss). Otherwise, the page is not in memory (a page fault) A simple TLB miss (refill TLB) Load the PTE into TLB and retry TLB hit What if the page table is not in memory? A page fault for the page table Could be handled in hardware or in software Little performance difference between the two approaches. A page fault (for instruction or data) OS handles fetching the corresponding page from the disc and updating the page table Then restart the faulting instruction Chapter 5 — Large and Fast: Exploiting Memory Hierarchy — 2 A TLB Hit A cache that contains a subset of the page table in the main memory If there is no matching entry in the TLB for a page, the page table must be examined. Since the page table has an entry for every virtual page, no tag field is needed Chapter 5 — Large and Fast: Exploiting Memory Hierarchy — 3 A simple TLB Miss A cache that contains a subset of the page table 1. TLB miss handler copy the page table entry without checking its valid bit. TLBmiss: 1 mfc0 $k1, Context # copy PTE address lw $k1, 0($k1) # get PTE mtc0 $k1, EtnryLo # put into a special reg tlbwr # put into TLB at random in the main memory eret # return It takes about a dozen clock cycles 2. re-try the address translation: TLB hit If there is no matching entry in the TLB for a page, the page table must be examined.

  • Addressing Modes
    4. Addressing modes The topic of this chapter are the addressing modes, the different ways the address of an operand in memory is specified and calculated. Although the computer's world offers a large variety of addressing modes, we will discuss only about the basic ones, those that are used the heaviest in programs. We begin with a discussion about memory addressing: our special concern in this section is how is data (especially if we allow different data sizes) retrieved from memory and what problems appear. 4.1. Interpreting memory addresses A major decision a designer faces is how is the memory to be addressed. Example 4.1 MEMORY ACCESS: You have to design a 16 bit architecture: show how you can access the memory if you allow byte and half-word addressing or only half-word. Answer: 2 45 1 23 0 16 bit data 0 8 bit data 8 bit data 1 a) only half word b) byte and half-word Virgil Bistriceanu Illinois Institute of Technology 55 4 Addressing modes If we have a n-bit wide architecture, and we always read/write from/to memory only n-bit wide data (in our case 16-bit architecture and read/write only half-words as in example 4.1a) then there are not very many hardware problems; an address always means a half-word. However, a problem appears when we try to manipulate characters (a character nicely fits a byte): • use a whole half-word for one character. In this case we waste a byte for every char; • use a half-word to accommodate two bytes (packed).
