Unformatted text preview: EEL 4744C – Dr. Gugel Last Name______________________________ First Name ______________ Fall 2009 Exam #2 UFID#__________________________________________ • Open book and open notes, 90-minute examination to be done in pencil. • No electronic devices are permitted. • All work and solutions are to be written on the exam where appropriate. Point System (for instructor and TA use only) Page 2 26 points _________________ Page 3 22 points _________________ Page 4 8 points _________________ Page 5 24 points _________________ Page 6 10 points _________________ Page 7 14 points _________________ TOTAL _________________ out of 100 Grade Review Information: ( NOTE: deadline of request for grade review is the day the exam is returned .) Page 2 Page Score = 1. A student would like to add a 16 bit output port and a 16 bit input port to their lab DSP board. However they don’t want to add any extra components other than those already on our DSP board. Use only the devices we provide on our board! Show how this can be accomplished with our DSP board and label all I/O signals as well as the circuitry required for address decoding . Assume that the output and input ports w ill be mapped to the same address and that there will be 256 images of this hardware in the memory map. Use DSP signals that will yield the least amount of address decoding circuitry required in the CPLD. i.e. Select DSP signals that will optimize your CPLD design. DO NOT use GPIO pins on the DSP to create the ports. Hint: The CPLD on your board can do more than just address decoding. Note: The simplest design will receive the highest pts. (18 pt.) 2. What is the address range for your ports (all 256 images) in your above design? (2 pt.) ______________________ Hex 3. Briefly write the steps required to initialize the DSP signals needed in your above design. i.e. pseudo code You may assume register names and are available for use. i.e. GPE_IOMux1 = 0xFF00 ;select GPEIO outputs 15:8 (6 pt.) ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ ______________________________________________ Page 3 Page Score = 4. Write code to read the input port and continuously echo it out the output port. (4 pt.) ______________________________________________ ______________________________________________...
