7. Memories


Memory characteristics and capacity. Memory types; RAM, ROM, EPROM. Dynamic RAM.


8. Programmable Logic


PLA. PAL. CPLD. FPGA

Teaching Methods

The teaching method is based in theoretical, practical and laboratory classes. Strong emphasis is placed on projecting, simulating and implementing logic circuits.

Assessment

The assessment is based on 2 parts: Theoretical (70%) and Laboratorial (30%)


Assessment elements are graded using the interval [0,20].


The theoretical part can be achieved either through 2 Tests or a Final Exam – Minimum grade 9.5



  • [F1] Test 1 – Minimum grade 8.0 (35%)

  • [F2] Test 2 - Minimum grade 8.0 (35%)

  • [Ex1] Final Exam 1 (70%)

  • [Ex2] Final Exam 2 (70%)


 


The Laboratorial part hás minimum grade 9.5



  • [L] Laboratory (30%)


 


[NF] Final Grade: NF = Max{(F1 + F2)/2; Ex1; Ex 2}×0.7 + L×0.3


 


If NF>= 9.5 : Approved


If NF< 9.5 :   Failed
