Web3. The Text tab displays the MIPS instructions loaded into memory to be executed. • From left-to-right, the memory address of an instruction, the contents of the address in hex, the actual MIPS instructions where register numbers are used, the MIPS assembly that you wrote, and any comments you made in your code are displayed. 4. WebIn mips_syscall, we begin by extracting the system call number from the trapframe's tf_v0 field. This means that the system call number was stored in register v0 prior to executing the syscall instruction. Then we simply switch on the system call number, with a separate "case" to handle each possible system call.
