Why ROM is always mapped in lower region of memory map in 8085?
rom values are permanent and we cant change its value.....we can only read but cant write it
How much maximum memory size that 8085 can access?
Yes and no. All memory location from 0H to 0FFFFH are addressable, but some of them are needed for the program, interrupt vectors, and the stack, so you would need to pay attention to where things are located in memory to design an appropriate program. In addition, if your system is using memory mapped I/O, some locations will be reserved.
What is a memory mapped register?
A memory mapped register is a register that has its specific address stored in a known memory location.
Differentiate between memory mapped IO and IO mapped IO?
Memory mapped IO is one where the processor and the IO device share the same memory location(memory) while IO mapped IO is one where the processor and the IO device have different memory located to each other.
The maximum number of Io devices can be interfaced with 8085 in the Io mapped Io technique?
3
How many memory location can be addressed by microprocessor 8085?
The 8085 can address 216, or 65536 different memory locations.
What is slow memory interfacing?
explain how slow memory get interfaced with 8085
What is the meaning of memory mapped bus?
Memory mapped buses helps in the extension of the address of the physical ram through which the devices can access the address
Which is used to connect low memory in 8085?
READY
What is the Difference between memory mapped IO and IO mapped IO?
In memory mapped I/O, a chunk of the CPU's address space is reserved for accessing I/O devices. In I/O mapped I/O, I/O devices are handled distinctly by the CPU and hence occupy a separate chunk of addresses predetermined by the CPU for I/O. In case of Memory mapped I/O the same address BUS is used for accessing both Memory (RAM) and the Registers of I/O devices. For I/O Mapped I/O, separate address BUS is used. As Address space is generally larger for Memory than I/O registers, the length of I/O address is larger in case of Memory Mapped I/O. For a system which uses I/O Mapped I/O, there is a requirement for a extra h/w Circuitry.
What is memory word addressing capability of 8085 µp?
64K
IN 8085 local variables will get stored in?
Registers or RAM-memory.
