Re: design and implementation of stack pointer in a processo
Used a adder(increment) and 2's complement circuit for decrement operation.
Also used buffers and tristate devices for proper data flow-control
stack pointer design
Please give some hints regarding internal processor design materials and sites and how a processor is implemented on paper at-least.
Even the most primitive design will be fine.Some material regarding the same will be most welcome.
Thanks in advance
Multi core Processor
Please provide some information regarding multicore architecture CPU and single core core CPU. Please provide some link to basic architechture differences and the pro and cons of both.
thanks in advance
please can any one provide me the proofs!!!
Denote a vector space of all functions
f:R -> R
which are infinetly differentiable by C^∞(R). This space is called the space of smooth functions.
a. Show that C^∞ is infinite dimensional.
b. Show that differentiation is a linear...
Can anyone help me to get the theory of MOSFET Charachteristics & operating principle on the net.
one more doubt what is hard & soft switching in the Mosfet. This i think is used for SMPS. please provide some solution(s) with details.
Thanks in Advance
differences of mosfet
I want to use mosfet or IGBT for switching application at high power & high voltage can someone list me all the differences between the MOSFET & IGBT.
Also LIST their advantages, disadvantages and features.
Thanks in advance
microcontroller and noisy environment
Can any one suggest a microcontroller which is highly immune to noise from 8051 family?
I am currently using 89C2051 for my application but the circuit is to be placed in very noisy environment. Noise level is high.
So please suggest a...
I have connected VCC AND GND to µC 89C2051, connected power on reset ckt (10µF & 8.2k resistor)as well as the crystal with 33pF capacitor (as per the datasheet)but still i m not getting the output from crystal (i.e. any waveform on the crystal pins). i have also connected 100nF...
I want to learn the transformer design techniques & implement a transformer.
Is there some short-cut that if we only electrical parameters i.e i/p & o/p voltage,i/p & o/p current and maximum frequency of operation we can get the core shape & material,no...
I want to implement a rectifier & controlcircuit with input variable voltage from90-270V current 3A & output should be 400VDC & output power to be 250W
basically i need a line regulation as output must be constant at 400V & 250W
Please suggest some design method/s
eoc signal adc
PWM will be a building block in my power supply project.
I have 400Vdc , 250Wpower as input
i want to vary this DC voltage from 100VDC to 300VDC
with coressponding analog contol input from 0 to 10V(source input current 50mA) i.e 0v-to 100v and so on.
for this i need pwm so how...
Can any one suggest some digital circuit or microcontroller based PWM which takes a control voltage range from 0 to 10 volts and output a digitally controlled PWM signal.
Thanks in Advance
Re: Power supply help
---Ambient temperature for operation:0° to 60°C
---Input voltage as mentioned earlier is:400Vdc Regulated (which is the o/p of a PFC circuit). Currcnt o/p is 0.6 amps (240W)
---The control voltage is variable from 0Vdc to 10Vdc and would source 50mA.
Re: inputs to 89C2051???
Can u tell me how to give a +5V or 0V as a input to 89C2051?
i want information on internal pull up facility i am not getting what is meant by pull up?
Added after 1 hours 48 minutes:
input is meant as to the port pins of port1 & port-3
