Write c code that does the following: 1. interactively read the coefficients of a quadratic equation and compute the two roots. the program must alert if there is no real root, i. e., read and c of 2 + + c = 0, and compute x = −±√ 2− ; note: a. sqrt() is available in math. h b. for putty/omega server, include -lm while compiling, i. e. gcc -lm myprogram. c c. make sure that you add a routine to check the positiveness of the discriminant using the if statement. show actual runs and examples

Which part of the cpu accepts data?

Consider a byte-addressable computer with 16mb of main memory, a cache capable of storing a total of 64kb of data and block size of 32 bytes. (a) how many bits in the memory address? (b) how many blocks are in the cache? (c) specify the format of the memory address, including names and sizes, when the cache is: 1. direct-mapped 2. 4-way set associative 3. fully associative

Write a program in plp assembly that counts up by one starting from zero (or one) inside a loop and writes this value to the leds every time the value is increased. the memory address of the leds is 0xf0200000. the table below shows the meaning and an example usage of the instructions covered in the video, plp instructions for project 1. instruction example usage meaning load immediate li $t0, 8 register $t0 is set to the value, 8. store word sw $t2, 0($t1) the value in register $t1 is used as the memory address. the value in register $t2 is copied into this memory address. add addiu $t4, $t3, 29 register $t4 is assigned the sum of 29 and the value in register $t3. jump j your_label_name the program jumps to the line following the label, "your_label_name: ". label your label name: defines a label called "your_label_name: " that can be jumped to
