Presentation Transcript

  1. Erik Jonsson School of Engineering and Computer Science EE/CE 2310 – HON/002 Introduction to Digital Systems http://www.utdallas.edu/~pervin Thursday: (P) Chapter 12, (T) 13-7 Tuesday 4-24-12 FEARLESS Engineering www.utdallas.edu/~pervin

  2. (T) 12 Microcomputer Memory RAM ROM PROM EPROM Bulk Storage

  3. Hard Disk Drives 5400 RPM, 7200 RPM, 9600 RPM

  4. Suppose we had 12000 RPM (Hot and Noisy) 12000/60 = 2000 RMS = 2 RPmS = 0.002 RPμS = 0.000002 RPnS Thus 1 revolution in 1/2000 S = ½ mS = 500 μS = 500000 nS And so average wait time just for rotation is: 250,000 nS

  5. (T)13.7 Programmable Logic Array (PLA) See pp. 326ff

  6. (P) 11.1 Pipelining

  7. (P) 11.2 Delayed Branches

  8. (P) 11.3 Caches

  9. (P) 11.4 Delayed Loads

  10. (P) *9.6 Fixed-point Numbers This will not be on the final exam but it wouldn’t hurt to know about it!

  11. FINAL: 8:00am 5/10
