Develop a Verilog model of the serial output controller of Exercise 8.21.
Exercise 8.21
Design a serial output controller for connection to the Gumnut core using the Wishbone bus. The controller should transmit each 8-bit data byte written to a data register using NRZ encoding with one start bit and one stop bit, as shown in Figure 8.35 on page 355. Transmission should occur at 9600 bits per second, with a transmit timing derived from a system clock with frequency 39.321600MHz ( 9600 4096). When the stop bit has been transmitted, the controller should set an interrupt request output. The interrupt request output should be reset when the Gumnut int_ack signal is 1.
Determine the value of the gain K so that the damping ratio ζ of the closed-loop system is equal to 0.5. Then determine also the undamped natural frequency ωn of the closed-loop system. Assuming that e(0)=1 and (0)=1 evaluate
A combined-cycle, natural-gas, power plant has an efficiency of 52%. Natural gas has an energy density of 55,340 kJ/kg and about 77% of the fuel is carbon. a. What is the heat rate of this plant expressed as kJ/kWh and Btu/kWh
Explain how a voltage is induced in the secondary winding of a transformer - What purpose does the no-load current of a transformer serve
A causal linear time-invariant continuous-time system has impulse response of h(t) when t is greater or equal to 0. compute the output response for all tgreater then or equal to 0 when the input is the unit step function u(t).
Construct a 4-to-16-line decoder with five 2-to-4-line decoders (74LS139A). Use a block diagram for components and clearly show your address select variables.
Search the web and the literature to find the capacity of the ERCOT power pool in the United States. Find the area covered and the size of the population served.
(a) Determine the rms value of the fundamental and each harmonic. (b) Write down an expression to represent the complex voltage waveform if the frequency of the fundamental is 31.83 Hz.
how the amplifiers should be connected. To proceed, evaluate the two possible connections between source S and load L, namely, SABL and SBAL. Find the voltage gain for each both as a ratio and in decibels. Which amplifier arrangement is best
Determine (a) the required step up voltage ratio for satisfactory performance; (b) the voltage ratio of a standard buck-boost transformer that most closely meets the requirements of the load with the buck-boost transformer installed.
The following MATLAB command has been used to perform offline filtering y=filter([0.8 -0.8],[1 -0.3],x); Where x and y are the input and output vectors, respectively. What is the transfer function of the filter
a single phase transformer has the following ratings: 10kVA,240/2400V. In the open circuit test with rated primary voltage(240V), the primary current is 0.85A and secondary voltage is2400V. A short circuit test is performed as follows
If a 60-Hz synchronous motor is to be operated at 50 Hz, will its synchronous reactance be the same as at 60 Hz, or will it change? (Hint: Think about the derivation of XS .)
