I am trying to replicate this Java function in MIPS:
...ANSWER
Answered 2021-May-14 at 22:52Found it. The trick in MIPS is that the print out command li $v0, 1 can override the value that you may want to print in $v0, that was my mistake. The work around is to store the data in another register first:
QUESTION
I am writing a tool for tracking jumps(JAL/JALR) instructions on riscv instructions. I am using https://github.com/illumine/disk-benchmark/blob/master/src/disk-benchmark.c disk benchmark to test my tool. The tool is tracking jumps on binary files when virtual functions and pthreads are not used but have difficulties to track when pthreads are used. Here is the objdump of binary file on riscv:
ANSWER
Answered 2021-May-11 at 02:44We can trace the jumps on binary file only if we don't have any indirect jumps and if the trace is not involved in library functions. In my case I couldn't trace since the program had a lot of pthreads and indirect jumps.

QUESTION
I am new to MIPS and writing a program of stack which reverses the elements in array.. i have tried everything to see if anything is wrong.. If anyone who can guide me?
...ANSWER
Answered 2021-Mar-31 at 20:20There are two issues in this program:
while you push something on satack you have to subtract the $sp by 4 bytes and then copy the operand to that location (in that order)
I don't know how can you forget that since you correctly added $sp while popping ... anyway
So you need to add
subu $sp, $sp, 4. (Oraddiu $sp, $sp, -4if your assembler doesn't turn sub into add for you.)in loop the
add $t2,$t1,0is wrong .. you should do$t1,$t1,1(because you seem to increment by one like i = i + 1) .. this mistake indirectly causes your loop to work incorrectly which compares t1 and t2 registers (and you updated t2 register wrongly)Adding 0 is just a copy, so that's not what you want either.
Here is the corrected code.
QUESTION
I just received some help with a problem I had with some MIPS code in this question (Trouble with MIPS array) and the code they gave me works fine. Now I'm trying to add a sorting algorithm to sort the integers stored in the array, but the output I get is just a 0 followed by the string I put as input (the correct output should be the date followed by the string). That's the code I'm working on:
...ANSWER
Answered 2021-Mar-31 at 18:18One approach would be to sort numeric array and keep track of corresponding entries in the string array (as you shuffle around the value in numeric array do the same thing in the string array). I suggest you start implementing a simple sorting algorithm and sort numbers first. For example, consider implementing bubble sort. For this you might consider implementing swap procedure to swap 2 values.
Here is he mips version of the program. It implements bubble sort procedure. I have hardcoded numeric and string arrays at the top of the file (so you have to do some adjustments to make it work with your code). The idea is the following: when I swap numbers in the numeric array I also swap corresponding strings in the string array.

I'm trying to get a subset of a pandas dataframe based on unique values.
My overall dataframe has around 5k rows, where each row has an ID and text, each ID can have multiple text entries. The dataframe something looks like this:

Answered 2021-Mar-31 at 09:22If it doesn't matter which 3 IDs, you could just get the first 3 with
unique_3 = df['ID'].unique[:3] and then select the rows with df_id = df[df["ID"].isin(unique_3)].

QUESTION
I am trying to using inline integration in Dymola to do real-time simulation, I take the Modelica.Fluid.Examples.HeatingSystem as an example, but no matter which inline integration method I choose, the simulation always fails.
- When I choose an explicit method, Dymola is unable to start the integration.
- When I choose an implicit method, Dymola got stuck.
- The special one is the Rosenbrock method, the error shows Dymola fails to differentiate some equations.
In my understandings, inline integration means adding the discretization equations to the model equations, then Dymola could do more symbolic manipulations and get a new BLT form. I understand this method could cause more algebraic loops and make it hard for Newton Method to solve these algebraic loops.
My questions are:
- Compared to the normal method in Dymola, what kind of model is more suitable for the inline integration method?
- Inline integration is designed to increase the simulation speed, but it could hard when the nonlinear algebraic loops are hard to solve, so is there a limitation or rule of using the inline integration method?
- Take the
Modelica.Fluid.Examples.HeatingSystemas the case, how could I adjust the model to use inline integration? - I know that Dymola only supports using the inline integration method with the Euler integrator(fixed step size integration algorithms), so why does the inline integration method only support fixed step size? Is it unnecessary to use variable step size? If not limited to real-time simulation, I just want to use inline integration to increase the simulation speed, is it possible to combine the inline integration method with DASSl?
ANSWER
Answered 2021-Feb-18 at 08:02It seems stuck for most implicit solvers because:
- It is a reasonable sized model that you integrate with milli-second timestep for 6 000 second; that means 6 million steps (each involving systems of equations).
- There is less feedback during inline integration (since giving that feedback takes too much time).
But implicit Euler isn't stuck - it just takes a couple of minutes to complete.
However, you can can increase the step-size for implicit Euler a lot for this model, it actually works fine with 1 s; and then completes in less than second.
Inline explicit Euler fails unless you use a lot smaller step-size (same as non-inline explicit Euler).
Note: The inline solvers in Dymola are all fixed-step-size solvers and thus setting a too short step-size will slow down the simulation and a too long step-size will cause the simulation to fail, whereas dassl, lsodar, radau, esdirk* all adjust the step-size during the integration to avoid both of those problems.

Install BLT
You can use BLT like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
