Final Review

University of Texas ECE

Logistics

 The Final is May 9th^ in CPE 2.

Common mistakes with Test 3

 Forgot to save a register that was used.

 If it is not defined in the use comments for the subroutine as being

destroyed than you must save it.

 How to count offsets for binding.

 Adding code that is not required

 Ldaa1,x+  Cmpa#0 ( This is NOT required the Z is set by the load)  BNE XYZ

 NOT reading all the material that was provided.

 Baud rate calcuation ( Forgetting the start bit)

 8 bits + 1 stop bit +parity = 11 total bits. (must include parity)

 Number conversions, 8-bit (fill in the blank)

 convert one format to another without a calculator

 signed decimale.g., -  unsigned decimale.g., 200  binarye.g., %  hexadecimale.g., $C

 volatile, nonvolatile

 structured program, flowchart, call graph, data flow graph

 basis, precision,

 fixed-point,

 given resolution convert between value and integer  value = integer*D  given precision and range choose the fixed-point format

 mask, toggle,

 ldaaPTT

 eora#$

 staaPTT

 8-bit versus 16-bit data

 reset vector, swi vector

 direction register

 baud rate, bandwidth, frame, start bit, stop bit, parity

 busy-waiting, gadfly, or polling

 flow chart, call graph, data flow graph

 device driver

 ADC 0<Vin<5 to 0<Dout<1023 If Vin=2.5V, then Dout=

 Straight binary format, example conversions  resolution, range, precision

 Timer_Wait

 Addd TCNT TCNT at end of delay

 Wloopcpd TCNT is EndT<TCNT

 bplWloop  Rts

 Debugging

 ScanPoint, intrusiveness, monitor, profiling, dump  measuring execution time, desk check, stabilization  Functional debugging, performance debugging, profiling

 Real time systems, bounded latency

 Matrices (address math, scanning, fixed size)

 row major, column major, bit/byte/word

 Tables (address math, scanning, fixed size)

 Producer/consumer problem

 Multiple Access Circular Queues, FIFO queues, double buffer

 Linked list (address math, scanning, fixed size, single/double)

 Memory allocation dynamic vs permanent

 local variables and parameters on the stack

 S binding, X stack frame binding

 binding , allocation, access, deallocation

 call by reference, call by value

 switrap rti instructions

 device driver

 ADC 0<Vin<5 to 0<Dout<1023 If Vin=2.5V, then Dout=
