ECE 3724/CS 3124 Microprocessors I Summer 2001Test #4Floating Point Numbers1. (4) Convert 53.6312510 to binary encoding in single precision floating point format?2. (4) What is the maximum range that can be produced using single precision floating point format?3. (4) How is sign represented in IEEE 754 format?4. (4) Using SIMD, the same instruction _______________________________________________.Busses5. (4) PCI supports a bus master concept. How does this affect the DMA controller?6. (4) What is the relationship between distance from the processor, bandwidth and latency for system busses, backplane busses, and peripheral busses?Serial I/O7. (4) How is the carry bit used when generating and recovering serial data? What instructions are used? Modems8. (4) The baud rate of a modem describes the number of __________________ per second and the data rate of a modem describes the number of __________________ per second. 9. (4) Asynchronous modems must resynchronize every ____________________.10. (4) How long will it take to transmit the ASCII letter B, assuming 1200 bps, 7 data bits, 1 start bit, no parity and 2 stop bits?11. (4) The _________ is a microprocessor compatible peripheral interface chip used to convert parallel data into serial data and serial data into parallel.12. (4) What clock rate is required for 1200bps data transfer using the device mentioned in question 11?13. (4) What must the parity bit be if the transmission is to be odd parity the character to be sent is 'R'?In lab 11, you installed a new ISR for the interrupt timer.14. (4)Write the code that will save the address of the interrupt vector table for interrupt 08h.15. (4) Write the code that will set up the interrupt vector table for an user written ISR called
