What architectural features will allow this microprocessor to access a separate
“I/O space”?
Microprocessor is the brain of a cell phone. It uses programs to access and utilize memory stored on microchips.
in main memory
Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. As the microprocessor processes data, it looks first in the cache memory and if it finds the data there (from a previous reading of data), it does not have to do the more time-consuming reading of data from larger memory.
The 8085 microprocessor can access 65536 (2^16) locations in memory, and 256 (2^8) locations in I/O space.
Its a Programmable Direct Memory Access (DMA) controller.
The 8086 microprocessor has a total of 20 address lines, allowing it to access up to 1 MB of memory. It features a total of 16-bit data ports, which can be used for data transfer. The microprocessor has several control and status pins, but it does not have dedicated I/O ports in the same way modern microcontrollers do. Instead, it interfaces with peripherals through its address and data buses, allowing for flexible communication with external devices.
Catche memory is categorized as form of random access memory (RAM) that computer microprocessor access quicker than regular RAM.
(00-FF) 256 devices!
microprocessor can access 2^8 points which is 256 then we have 8 bit memory = 1 bytes then 1*256 =256 bytes
DMA->Direct Memory Access. I/O device can access the memory without the help of CPU. So that there is faster access by the device. I/O device signals microprocessor by HOLD signal.
The Royal Liver Building in Liverpool features a total of 10 floors and is known to have 500 stairs. However, access to the top floors is typically restricted to authorized personnel and does not allow public access. The building is an iconic part of Liverpool's skyline and is recognized for its historical significance and architectural style.
Architectural records of local buildings can be found at a local library or historical society. Many towns keep these records on file which you can access.
