[Solved]4 Learned Floating Point Instructions Registers Convert Vector Vector Multiplication Code Q37139124
4. Now that you learned floating-point instructions and registers, convert your Vector-Vector Multiplication code implemented for HW4 to use floating-point data. Use the following C code for main function. Reuse your vector_mul subroutine.s file implemented for HW4 and replace instructions with floating-point operations properly. The input data should be changed like in the following C code. Cortex-M3 does not support floating point unit (FPU). Thus, we will use CorTex-M4 for this homework. Create a new project just like you created the other projects, except for the target core which should be ARMCM4_FP like below image (Choose ARM Cortex M4-ARMCM4 FP in step 2 of”Create and run a new project” in uVision_Install _Guide.pdf). The other steps are the same; you should use the same startup file that we used for the past projects. l .As tloating-point data is not casy to understand the valuc at a glance, the expocted ARM result value of each loop iterution and the final result ure provided below. If your computation result of each iteration and final result match these data, your code will be rcgarded as corrcct.
