mips32

I started Verilog a few weeks ago and now I'm implementing MIPS pipelining on an FPGA board and I'm on the MEM part of the pipelining stage. I'm trying to code the Data memory unit (in picture -> Data memory Unit). I don't understand the use of memread. I understand that if memwrite is 1, the contents of the current address is passed to read data. So far, this is my code: module data_memory ( input wire [31:0] addr, // Memory Address input wire [31:0] write_data, // Memory Address Contents input wire memwrite, memread, output reg [31:0] read_data // Output of Memory Address Contents ); reg [31

Can someone please give me pointers on how I can go about making a code that multiplies using shifts in MIPS assembly? I don't understand how having a number 2^n can help me multiply using an odd multiplicand I currently have this code, I'm trying to make a calculator .text li $v0, 4 la $a0, ask_1 syscall li $v0,5 syscall move $s1, $v0 li $v0, 4 la $a0, ask_2 syscall li $v0,5 syscall move $s2, $v0 #sll $s2, $s2, 3 #$s2 * $s2^3 = result srl $s2, $s2, 1 li $v0, 1 la $a0, ($s2) syscall .data ask_1: .asciiz "Enter Multiplier\n" ask_2: .asciiz "Enter Multiplicand\n" result: .asciiz "The Answer is:

I've an interesting question! I implemented a memorizing game in MIPS, The game starts by randomly printing a number between 10-99 on the screen, then ask the user to enter the exact number. If the user enters the number correctly, the game continues by displaying the first number and a second randomly generated number between 10-99. and the two numbers have to displayed one after another with a 3 second delay between them. The users is then is asked to enter the numbers in the correct order as they appeared on the screen. If the user enters the two numbers correctly the game continues with

When determining the size of .asciiz string, should I take into consideration the terminating character ? For example: .data string: .asciiz "Hello" The size of "string" is 5 or 6 (byte) ? Thank you in advance. if you are asking about how many bytes in memory the string is stored in then it's 6 bytes if you are asking about what should be returned by a function that count the string length (strlen C function for example) it should be 5 This particular asciiz string requires 6 bytes of storage. In programming situations, you will measure the string size to be 5. As in strlen() . When using this
