MIPS PROGRAM  (catz.asm) Develop a MIPS the following MIPS program. B. (catz.asm) Develop MIPS program to writes out text strings to produce the output as shown below. FAT CAT RAN FAST Requirements: 0. Name the file catz.asm 1. Name the strings Fat, Cat, Ran and Fast. 2. The output must be aligned exactly as shown. 3. Run Qtspim (PCSPIM) on catz.asm. 4. Save the log file as catz.log. 5. Submit catz.asm and catz.log. Hint: 1. rename the DEMO program demo.asm file to catz.asm. 2. Mark up the source listing to delete unneeded data and instructions. 3. Create/rename strings to meet requirements of this assignment.
