Challenge Problems
Push your limits with advanced challenges
You have a microprocessor with 64 KB of addressable space. If you want to add a new memory chip that requires an address space of 16 KB starting from 3000H, what changes need to be made in the memory map?
💡 Hint: Check the existing assignments and ensure the new memory fits within the total space.
Create a schematic diagram showing how to connect a decoder IC for a system with one 4KB RAM chip and one 2KB ROM chip. Illustrate the address lines needed and detail which lines trigger the chip select signals.
💡 Hint: Use logical gates as indicated in your lecture for generating unique chip select signals.
