1. The goal is to design a memory system to support a small amount of data storage outside of the processor. The design is to be based on the 16K bit CY7C128A SRAM organized as 2Kx8.(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 separate 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.
2. For the following aspects of an embedded application, provide a data and control flow diagram.(a) Reading/writing from/to a USB port and a general parallel port(b) Accessing and reading a mouse(c) Accessing and reading keys from a keyboard(d) Controlling and accessing a digital-to-analog convert(e) Controlling and accessing analog-to-digital convert(f) Burning a CD(g) Transferring data from an external device to memory and then to a display(h) Managing and controlling a video on demand system in a motel or hotel(i) An automatic process for filling and capping bottle of juice on an assembly line
Write the VHDL text file for a circuit to implement the arithmetic circuit that subtracts two 12-bit numbers (B from A) and adds a third 12-bit number (C) from the result. Use INTEGER types
Design channel coding performance simulator that compares two channel coding technique X and Y . You can provide pseudocode or block diagram of the simulator.
Submit an excel spreadsheet with your characterization results, and a screen shot of you amplifier schematics, and your simulation result running a sin wave (Use a vsin for input).
A three-phase transmission line having a reactance of 120 ohms per phase is connected to a wye-connected load whose resistance is 160 ohms per phase. If the supply volatge is 70kV line-to-line, calculate a) The line-to-neutral voltage per phase.
Design a 1024x16 RAM using the 256x8 RAM blocks and neccessary combinational circuit. Note that, 256x8 RAM block has 8 bit data (DATA), 8 bit address (ADRS), chip select (CS), read/write (R/W) inputs and a three-state output bus.
The magnetization graph taken at 1800 rpm of a 6 kW, 120 V, 50 A, 1800 rpm, dc generator is attached below. Field resistance is 20 ohms and armature resistance is .18 ohms. Find: As a seperately excited generator
The power supplied by a certain source is a constant 7.5 W over the first 5.8 min, zero for the next 2.8 min, a value that increases linearly from zero to 10 W during the next 8.8 min, and a value that decreases linearly from 10 W to zero
How are the left (L) and right (R) signals obtained separately in the radio receiver to drive the dual channel audio amplifier and speakers?
Vs=310 V (Vrms=219 V) at the input of bridge rectifier Need LC filter at the output of bridge which can provide 240 V +-10V DC, with 2 A constant current. find method to find appropriate values of LC which can provide these specification.
The 741 op amp is usually modeled on specification sheets as a voltage amplifier having the following parameters: Rin = 1 M, Av = 100,000, and Rout = 100 Using this information, develop equivalent circuits for the 741 as a current amplifier
Design the combinational logic circuit for an elevator controller such that the option to go up or down by only one floor is disabled. Assume that the building the elevator is in has 4 floors. Your inputs are the current floor and the next request..
