I was reading a research paper and came across these two terms: Architected Register File and Dependance Maps. What do these terms exactly mean? I could not find it anywhere on the internet.
**broken link removed** is the link to the research paper. Look on page 6 on the right column under the...
Re: Matlab & AT89S51
I have written some code in Matlab GUI for a button which is to be pressed after the input of angle and selection of a radio button corresponding to either clockwise or anti-clockwise direction:
function move_it_Callback(hObject, eventdata, handles)
ccw_selected = get...
I want to interface MATLAB (GUI) with AT89S51 uC to control the direction and angle of a bi-polar stepper motor. How should I proceed? The questions that I have in my mind include:
1. Can I send the no. of steps first in one byte of data, then another byte of data containing the direction data...
Is it possible that I am driving a stepper motor (bi-polar) from Port 3 of the uC (AT89S51) and at the same time I am sending and receiving data serially from the pins 3.0 and 3.1 (not simultaneously, but one after the other)? Actually I want to send the data to some register from the PC using...
Problem solved!
1. Connect 555 Timer (or some Schmitt Trigger device, though I haven't tested the Schmitt Trigger solution) at the output of the slit-hole IR sensor. The circuit diagram can be found **broken link removed**.
2. Make P3.4 high, for safe-side.
3. Yes you can! Make sure you make it...
Thank you all! The problem was solved by using a 555 timer at the output of the slit-hole sensor and connecting the output of 555 timer to the uC. The circuit diagram can be downloaded from **broken link removed**...
I am using OMRON EE-SM3 Opto-Switch (Sensor TX + RX Unit) for inputting clock pulses to uController through its timer pin. The problem is that when I pass an opaque object through its slit once, it counts it multiple times (i.e. counter increments more than once).
Is there any remedy circuit...
Opto-Switch Interfacing
Hello,
I am basically trying to interface a through-hole IR opto-switch sensor (**broken link removed**) with Atmel 89S51 uC for counting purposes (i.e. I intend it to generate clock pulses when something opaque passes through its slit). I want to connect it to Timer 0...
Thanks brother! Another question: Can the counting go faster than the execution of a single line of code (e.g. count increases by 10, but only one assembly line code is executed by that time). What to do in that case? Can I use some kind of interrupt for that situation, because I want to...
Using 8051, how can I achieve the following thing:
During the normal execution of a code (in an infinite while loop), I am simultaneously counting pulses from Timer 1 and as soon as the count reaches a particular value, I want to stop the normal execution of program (i.e. the while loop and...
Why is the sinking current higher than Sourcing current for IC's like 74 series etc. and microcontrollers? e.g. for 74LS series Sink current is 0.4 mA whereas 20 uA only
I have three questions regarding your simple power amplifier:
1) If I change my VCC to +9V, how would you recalculate the values of R2 and R6 (i.e. 330 ohm resistors)
2) What is the name given to the lower 2N3904 transistor (is it known as the driver?)?
3) How have you calculated the value of...
Actually, you see, I am new to designing Audio Amplifiers. What I want to know is how things work, so that I can design them the way I want. The working of (my) CE Stage and the complementary push-pull region of the output stage is clear to me. I am confused about the working of (refer to the...
Thanks a lot people (especially AudioGuru)!
Actually now I am interested in designing my own power amplifier and I want to know how you select those resistors values (i.e. why those, why not some other values). I shall be very thankful if you guide me or give me a reference to some book or...
