Re: SPIM Errors 14 Years Ago by dansnyderECE Yes, is this incorrect? Re: SPIM Errors 14 Years Ago by nezachem I suppose so. The g++ you are using is not a cross-compiler, it targets the host, that is generates the intel assembly. The compiler that targets MIPS (judging from your makefile) is $(XTOOLSPREFIX)/bin/mipseb-linux-g++. To obtain a MIPS assembly, use a following makefile: [CODE]inclide mips.mk file.asm: file.cpp $(CXX) $(CXXFLAGS) -S file.cpp… Re: SPIM Errors 14 Years Ago by dansnyderECE I'm still getting a similar error. Well, it seems to make sense that my compiler isn't compiling into MIPS correctly. Is it possible to do a hex dump on a .s file? SPIM Assembly HELP!!!! 17 Years Ago by Xeon1st Hi, I need to write a program that receives a 20 char string from the user and transforms lowercase to uppercase letter, but it should not affect any other character not included in the lowercase range (97-122, a-z). I wrote my program and the filters for the a-z configuration but it doesn't returns what it should return. Eg. "hello world&… Re: SPIM Assembly HELP!!!! 17 Years Ago by Salem > beqz $t5,exit #if char in array(i)=null 1. This test should be first 2. Should it be testing $t3, what you loaded from the array? > lb $t3,array($t1) Earlier, you assigned $t3 to be the lower bound, and now you're trashing it. Re: SPIM Assembly HELP!!!! 17 Years Ago by Xeon1st Thanks for the pointed problems. I made the corrections but the problem still exists. It doesn't show what it should show. It just printing the characters i already entered. The test with $t3 must be done so the program will recognise if the character is lowercase or not. If it is lower case then it should make it uppercase else do nothing. Do you … Re: SPIM Assembly HELP!!!! 17 Years Ago by Salem What's $t2 used for? Post your latest code. Re: SPIM Assembly HELP!!!! 17 Years Ago by Xeon1st The $t2 is set to check the counter. This is my latest code. Still not giving the correct result. [CODE].data .align 0 array: .space 20 msg1: .asciiz "Please enter 20 characters\n" .text .globl main main: #prompting user for 20 char addi $v0,$0,4 la $a0,msg1 syscall #storring string in array addi $v0,$0,8 la $a0,… Re: SPIM Assembly HELP!!!! 17 Years Ago by Xeon1st By the way there is another correction. At "exit" function the lw $a0,array is lb $a0,array. Re: SPIM Assembly HELP!!!! 17 Years Ago by Salem > addi $v0,$0,4 > la $a0,msg1 This is how you print a message to begin with - note the 'la' > At "exit" function the lw $a0,array is lb $a0,array. Both of which would seem to be wrong, what about la, to match the example at the start. You're supposed to be loading the address at where the array starts, not some character stored … SPIM Syntax Issue 14 Years Ago by dansnyderECE I don't understand what the issue is here. Here is the line in question: [CODE]beqz $t0, main[/CODE] and I get a syntax error here. Also, why is it that I cannot use the $at register? Also, I get a syntax error fr this line: [CODE]move $a0,$v0[/CODE] Whats wrong here? Re: Multiplying numbers in spim 17 Years Ago by Salem Posting your error messages as well would be a big help. Re: Multiplying numbers in spim 15 Years Ago by afuller454 I am not sure if this will help, but the syntax for mult is mult Rsrc1, Rsrc2 This leaves the low order bits in lo, and the high order bits in hi. Maybe what you are looking for is mul - mul Rdest, Rsrc1, Src2 Let us know if this makes a difference- Re: complete SPIM beginner 17 Years Ago by Duoas It just moves data around.

But why are you dividing by 2 instead of 10? You will need to add '0' 30 hex to each nested result, to change 0...9 to 30-39 hex. Also....???
