  1. עוד פתרונות • Superpipelining – יותר שלבים • Dynamic pipeline scheduling • Superscalar- שלבים במקביל

  2. חשב: loop: addi $5,$5,1 lw $9,sum($5) sw $7,sum($5) beq $7,$8,loop addi $9,$9,1 addi $9,$9,2 addi $9,$9,3

  3. היראכיה של הזיכרון SRAM 2 - 25ns $100 to $250 per Mbyte. Cache DRAM 60-120ns $5 to $10 per Mbyte. Memory Disk 10 to 20 million ns $.10 to $.20 per Mbyte. Disk משתמשים רוצים זיכרון מהיר וזול הפתרון היראכיה של הזיכרון

  4. If an item is referenced • temporal locality: לוקאליות בזמן • spatial locality: לוקאליות במרחב המונחים המרכזיים: Block: Hit: Miss:

  5. Direct Mapped Cache

  6. For MIPS:

  7. טיפול בכתיבה • Write through memory,cache התוכן נכתב ל- • Write buffer • Write-back

  8. Spatial locality

  9. הקשר בין בלוק ל- MISS RATE

  10. Directed mapped Set associative Fully associative
