A memory system is needed in a new design to support a small amount of data storage outside of the processor. The design is o be based on the 16 K bit CY7C128A SRAM organized as 2 K x 8.
(a) Provide a high-level block diagram for such an interface.
(b) Provide a high-level timing diagram for the interface to the SRAM from the microprocessor, assuming that seperate address and data busses are available. Define any control signals that may be necessary.
(c) Design the interface based on the timing diagram from part (a)
(d) Analyze the memory performance for a write and read operation of 1, 10, and 100 bytes.
Model and simulate a 4-to-1 multiplexer using (a) Dataflow Modeling, (b) Behavioral Modeling, and (c) Structural Modeling. Use Modelsim and a VHDL test bench to simulate all the three models for a 4-to-1 multiplexer.
Given the following function: F(W,X,Y,Z) = fm(2,3,5,7,12,13). a. Implement the function using an 8-input multiplexer. b. Implement the function using a 4-input multiplexer.
Write a sequence of instructions to initialize and run the timer to geneate an 800 baud rate clock. what would be the baud rate if the intial value of the timer was set to 9AH
Refer to the Wheatstone Bridge diagram. If R1=1ohm, R2=111ohm, Runknown= 1ohm, R3 is set at 1Kohm, and the battery is 9V:What is the current flowing through the galvanometerohm Use 60ohm for the internal galvanometer resistance in calculations.
Design a Common Emitter amplifier with no bypass capacitor which has an overall gain of AV=-15 when the input voltage has a source impedance (Rsource) of 2k, and the amplifier itself has an Rin= 4k, Rload= 6k,VCC= 15V,VBE= 0.7V
Problem 1: It is desired that an Arduino along with an EduShield be used to control 6 camerassimultaneously. Each is made by a dierent company: a Canon, a Nikon, an Olympus, a Pentax,a Sony, and a Minolta.
A) Compare and contrast the following serial bus architectures: I2C, CAN, UART. Discuss the hardware implementation, communication protocol, and typical applications of each. B) Explain the concept of bit dominance used in CAN bus.
A block error detecting code has a minimum distance of three. How many errors can this code detect and how many can it correct
A proportional control system is to be used to control the wing flap of a jet airplane. The wind load is expected to cause as much as 600 in-lb of torque. The system should be able to keep the flaps with 5o of the set point.
Draw schematic for a Bridge (full-wave) peak-rectifier capable of providing de output voltage of 12V with a ±1 V ripple and a load current of 0.5A. Calculate the transformer ratio, the filter capacitor value, and the PIV for the diodes.
(a) Howmany 256M X 16 RAMchips are needed to provide amemory capacity of 8 GB (b) How many address lines are needed to address this memory (c) How many address lines need to go to each chip
Consider an RLC circuit with R = 5 Ohms, L= ½ H, C= 2/9 F and input voltage e(t) = exp(-t/2)a. Starting from KVL show that the DE for the voltage across R is given by: v'' + 10 v' + 9 v = -5 exp(-0.5 t) b. Find vc in terms of the arbitrary constants ..
