Assemblers and Compilers
Each topic’s questions are grouped into three categories: basic, intermediate, and challenging. You are recommended to do all basic problem set before advancing further.
The amount of practice problems in this set is smaller than usual because the topics learned this week is mainly to set up the knowledge required for the next topic. You will have more practice hand-assembling C instructions during our lab.
Byte Memory Array Loading (Basic)
The memory is loaded as a byte array {14, 00, 3F, 60, 18, 00, 5F, 60, 00, 10, 01, 80, 1C, 00, 1F, 64, 00, 00, 00, 00, 02, 00, 00, 00, 04, 00, 00, 00, 00, 00, 00, 00} before starting execution.
For example, this means that MEM[0] = 0x14 and MEM[2] = 0x3F and so on.
What is the WORD at memory address 0xC? And what is the word at memory address 0x14?
MEM[0xC] = 64 1F 00 1C, and MEM[0x14] = 00 00 00 02.
