ARCHITECTURE synthesis1 OF vending IS
TYPE statetype IS (Idle, Opt1, Opt2, Error);
SIGNAL currentstate, nextstate : statetype;
BEGIN
fsm1: PROCESS( buttons, currentstate ) -- Is necessary to give the PROCESS bl a name?
BEGIN
-- Process the input
END PROCESS;
END synthesis1;
Is necessary to give the Process a name? Why should I set the name?
No. It is not necessary. It is optional. However, sometimes it is useful to give a process (or other statement) a name, for example, to make your code easier to read.

Program :
package main
import (
"fmt"
)
func main() {
ch := make(chan int)
fmt.Println(ch)
fmt.Println(0xc000062060)
}
Output :
0xc00009e000
824634122336
What does that output (824634122336) mean?
I think (0xc00009e000) is a starting address of an channel.
If (0xc00009e000 is address of channel)
Then please tell me what is this (824634122336)
else
Then please tell what are those outputs.
0xc00009e000 is a hexadecimal value of 824634122336. So 824634122336 not a value in the channel.
fmt.Println(0x10) //Output: 16
In software calculations, "0x" prefix adding to represent the hexadecimal numbers.

I want to output a clock signal via a DDR register. The target FPGA is an Intel MAX 10 (10M16DAU324I7G) FPGA. I instantiate an ALTDDIO_OUT component as shown in the code below. However, the output Pin stays permanently low. Clock is running, Pin in R15.
Can anyone provide a hint what my problem could be?
library ieee;
use ieee.std_logic_1164.all;
library altera_mf;
use altera_mf.altera_mf_components.all;
entity ddr_test
port(
clk_in : in std_logic;
clk_out : out std_logic
);
end entity ddr_test;
architecture rtl of ddr_test is
signal s_clk : std_logic;
begin
s_clk <= clk_in; --omitted the global clock network for simplicity
i_ODDR : component ALTDDIO_OUT
generic map(
width => 1
)
port(
datain_h => "1",
datain_l => "0",
outclock => s_clk,
dataout(0) => clk_out
);
end architecture rtl;
Direct instantiation of the ALTDDIO_OUT primitive does not seem to work reliably on the chosen FPGA and/or tool chain (MAX 10, Quartus Prime 18.1).
The solution is to generate an IP core with the MegaWizard GPIO Lite Intel FPGA IP using a DDR register output.

I have find batch file that start wifi hotspot automaticaly ,So I need to make a program in visual studio to run that batch file
Execute batch-file to start wifi hotspot as admin
// Start the child process.
Process p = new Process();
// Redirect the output stream of the child process.
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "YOURBATCHFILE.bat";
p.Start();
// Do not wait for the child process to exit before
// reading to the end of its redirected stream.
// p.WaitForExit();
// Read the output stream first and then wait.
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();
Code is from MSDN.
Simply Write a program containing this line of code:
System.Diagnostics.Process.Start("c:\\batchfilename.bat");
Should work for your belonings.

I want to write a procedure that creates a beep sound on Windows, using assembly language.
How can I do that? Do you have any starting point idea?
In MS-DOS, which is what many assembly novices are targeting without even knowing it, outputting character ASCII 7 (BEL) via interrupt 21h, function AH=2 will do it:
mov ah, 2
mov dl, 7
int 21h
In Windows, call the MessageBeep() API function, passing 0xffffffff as the parameter. The function resides in User[32].dll; depending on your assembler, the sequence for importing an API function might vary.
If by "Windows" you mean "DOS executable running under Windows", which some people occasionally do, then back to int21h.

I would like to generate a stack trace report like one generated by kernel oops.
------------[ cut here ]------------
kernel BUG at /home/administrator/project/systech/bsp_tan/linux-.2.6/arch/arm/include/asm/dma-mapping.h:325!
Internal error: Oops - undefined instruction: 0 [#1] PREEMPT

Where it's defined and how I can trigger it with in my module.
EDIT 1
How to find the line number where the PC (program counter) was when this bug happened.
PC is at my_func + 0x118/0x230
What this means?
Thanks in advance.
this is in the following files:
