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. Part 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
A votage pulse of amplitutde 10V begins at 5-sec and lasts for 20 msec,which is short compared with the respponse times and time constants of the system.This impulse si then passed through and integrator.
Will the electric field inside change (how much if yes)? Will the stored energy in the capacitor change (how much if yes)?
A common-source FET amplifier has an RD = 1.0 k ohms. How much does the gain change when a load resistance of 1.0 k ohms is capacitively coupled to the drain
A series circuit consisting of a 30-µF capacitor and a 0.155-henry inductor is connected to a 120-volt 60-cycle source. Calculate the circuit current and indicate whether it lags behind or leads the voltage.
What frequency crystals must be connected between the X1 and X2 inputs of the clock generator if an 8088-2 is to runat full speed
An MFSK modulation scheme with M = 4has a carrier frequency of 250 kHz, a difference frequency of 25 kHz, and two bits per signal element. Make a frequency assignment for each of the possible data combinations.
If you have 16 kibibytes of memory plus a few (less than 10) memory mapped devices (assume that each device uses 16 bytes of address space), what should the address size be
Data at a rate of 2 Mbps is to be transmitted via a pass-band communication system whose carrier frequency is 500MHz. A binary antipodal system with roll-off factor of 0.2 is used for this communication.
The stepped cylindrical tank is initially filled with liquid water at STP to a height H1. Subsequently, a plug at the bottom of the tank is removed to allow water to flow from the small hole of diameter d. The velocity v of the flowing water
