EXTRA CREDIT: Yоur pаtient is in the stаndаrd testing pоsitiоn for goniometric measurement (ROM) for shoulder internal and external rotation. The patient starts with the shoulder in neutral rotation, and in order to test the external rotation range of motion, you ask them to externally rotate. When you demonstrate the motion that you want them to do, you keep your wrist in neutral the entire time. As the patient moves the shoulder into the requested position, what type of muscle contraction is occurring in the wrist flexors?

The fоllоwing аssumes оur implementаtion of the RV32I аrchitecture. Consider following table that represents several of the 32-bit registers in the register file: REGISTER CONTENTS (binary) R10 0000 0000 0000 0000 0000 1010 0001 1000 R11 0000 0000 0000 0000 0000 1010 0010 0000 R12 0000 0000 0000 0000 0000 1010 0010 0100 R13 0000 0000 0000 0000 0000 1100 0010 1000 R14 0000 0000 0000 0000 0000 1100 0011 0100 R15 0000 0000 0000 0000 0000 1100 0011 1000 Also consider the following table that represents part of the memory of a 32-bit address space that has an addressability of 1 byte: ADDRESS (hex) CONTENTS (binary) 0x00000C38 0000 0000 1101 0101 0000 0110 0011 0011 0x00000C34 0000 0001 1111 0101 0010 0110 0000 0011 0x00000C30 0000 0000 0000 0111 0000 0000 0110 0111 0x00000C2C 0000 0000 0000 0111 1000 0000 0110 0111 0x00000C28 0000 0001 1000 0101 0010 0110 1000 0011 ... ... 0x00000A24 0000 0000 1010 1000 0000 0101 1011 0011 0x00000A20 0000 0001 1001 0101 1010 0110 1000 0011 0x00000A1C 0000 0000 1011 0101 0000 1000 0011 0011 0x00000A18 0000 0000 0000 1000 0000 0000 0110 0111 ... ... 0x0000033C 0000 0000 0000 0101 1000 0000 0110 0111 0x00000338 0000 0000 0000 0101 0000 0000 0110 0111 0x00000334 0000 0000 0000 0111 0000 0000 0110 0111 0x00000330 0000 0000 0000 0110 0000 0000 0110 0111 ... ...

The table above shows the addresses in hex (base 16) and the contents at the corresponding address in binary (base 2). A.) Interpret the contents at address 0x0C0C as two ASCII characters. [ascii] B.) Interpret the contents at the same address as A.) above as an unsigned integer in base 10. [unsigned] C.) Assume address 0x0C0E holds the more significant digits of a value (the high 16 bits) and address 0x0C0D holds the least significant digits of the same value (the low 16 bits). Interpret the resultant value an RV32I instruction to determine the operation. (Enter either ADD, JR, LW, or OTHER if it is not one of the first 3) [instr1] Recall that a memory location can store an address. We call that memory location's contents a "pointer" since it's an address that "points" to another memory location. D.)
