XTEA Encryption/Decryption VHDL Engine

Hello can you help me with this project it’s going to be similar to lab 4 that I have attached. I have attached the project pdf too ([login to view URL] 193.22 KB) this one Division.c #include "system.h" #include "altera_avalon_pio_regs.h" #include <stdio.h> /* register offset definitions */ #define DVND_REG_OFT 0 // dividend register address offset #define DVSR_REG_OFT 1 // divisor register address offset #define STRT_REG_OFT 2 // start register address offset #define QUOT_REG_OFT 3 #define REMN_REG_OFT 4 #define REDY_REG_OFT 5 #define DONE_REG_OFT 6 /* main program */ int main () { alt_u32 a, b, q, r, ready, done; printf("Division accelerator test #2: \n\n"); while (1){ printf "Perform division a / b = q remainder r\n"); printf("Enter a: " ); scanf ('"/.d", fea); printf("Enter b: " ); scanf("%d", &b); /* send data to division accelerator */ I0WR(DIV32_BASE, DVND_REG_OFT, a ); I0WR(DIV32_BASE, DVSR_REG_OFT, b ); /* wait until the division accelerator is ready */ while(1) { ready = IORD(DIV32_BASE, REDY_REG_OFT) & 0x00000001; if (ready == l) break; } /* generate a 1—pulse */ printf( "S t a r t . . . \ n"); I0WR(DIV32_BASE, STRT_REG_OFT, 1); /* wait for completion */ while (1) { done = I0RD(DIV32_BASE, DONE_REG_OFT) & 0x00000001; if (done == l) break ; } /* clear done-tick register */ I0WR(DIV32_BASE, DONE_REG_OFT, 1); /* retrieve results from division accelerator */ q = I0RD(DIV32_BASE, QUOT_REG_OFT); r = I0RD(DIV32_BASE, REMN_REG_OFT); printf("Hardware: %u / %u = %u remainder %u\n", a, b, q, r ); /* compare results with built in C operators */ printf( "Software: %u / %u = %u remainder y , %u\n\n\n", a, b, a/b , a%,b) ; }//end while }
