Question

Write an MIPS assembly program to exercise system call 1, 2, 4, 5, 6, 8, 10, 11 and 12. You are required to provide the source code, as well as the screenshots of the running of the programming in QtSpim System Call Code Service Result uments $a0-value Sf12 float value $f12- double value Sa0-address of string (none) (none) (none) Sa0-address where string to be stored (none) (none) (none) (none) SvO value read sfo value read sf0 -value read print integer print float print double 2 4 print string read integer read float read double read string none Sal-number of characters to read 1 memory allocation Sao number of bytes of storage desired SvO address of block exit (end of program) print character read character (none) Sa0integer (none) 10 (none) (none) char in Sv0 12
