3- i and test are defined as 32 bit integer, so there will be no stretches over a word boundry, and those are the only variables i used in the for loop.
4- yes, its gcc.
1- I don't have some thing with 'char misalign', all what I have is i, test and they are unsigned integer 32 bit and PPC405 is a 32 bit device.
2- Compiler is set to no optimization.
3- Even if I have 'char misalign', why would it affect the timing of the for loop? the loop is independent from...
Hello,
I'm programming a PPC405 in c on a devolpment board, I didn't enable the cache and I set the compiler option to no optimization. I'm trying to measure the execution time for a simple for loop with a HW timer on an FPGA some thing like this:
i, test is defined as unsigned integer 32 bit...
Hello,
I have a question regarding disabling the cache for the PPC405 in Vertix II Pro. When I start using the wizard to create a new project in XPS and during the process, there was an option to enable or disable the cache, but what if I would like to change that setting after finishing the...
Hello,
I've a problem when calling a procedure a passing variable to it, I tried my code in Quartus and compiled without errors but when I tried xilinx XPS which I have to use, I got the following error (undefined signal "aprio")
The code is down, any help???
architecture rtl of mylogic is...
Hi all,
If I assign a signal before a long for loop in a process, will that signal wait until the end of the process to take place?
ie process (a) is
variable cnt : std_logic_vector(0 to 15) :=X"0000";
begin
active <= '1';
for i 0 to 1000 loop...
Hello all,
I'm new to VHDL and having a problem.
I know that signal assignment does not take effect until the end of the process unlike the variable assignment.
ie cnt <= cnt +1;
out <= cnt;
If cnt is a signal then out will have the value of cnt before adding 1.
My...
