Consider the following system microprocessor based system Pr

Consider the following system microprocessor based system: Program the PLD such that interface memory chips at following starting addresses: Memory chip Starting address Ending address PLD Instruction (Program) Chip # 0 10000H Chip # 1 30000H Chip # 2 50000H Chip # 3 18000H Chip # 4 2F000H What is the capacity of each memory chip? How much total memory can you interface to the PLD? What is the MPU memory space?

Solution

MPU registers
