What is role of cache memory in microprocessor what are the typical cache capacities of p4 processor?

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.

Why memory to memory acess is not possible in 8086 micro processor?
Memory to memory access is certainly possible in the 8086/8088 microprocessor. Look at the repeated string copy instructions.
What is memory space in microprocessor?
memory space in microprocessor means cache ,it is the part of the microprocessor which contains the memory to store instructions which are used to perform different functions by the processor. where cache1 is referred to memory in microprocessor and cache2 is placed on motherboard which also contains memory to store instructions. Memory space can also mean the total size of virtual memory that a CPU can address, and the layout (flat or segmented) of this space. Most modern CPUs found in PCs (AMD and Intel x86_64 chips) are 64-bit CPUs, but, due to cost and practical use considerations, limit their virtual memory space to be 48-bits (or less).
What is microprocessor architecture?
Microprocessor Architecture is the design of Processor's functioning. It defines how devices are controlled, Execution of Data, Physical connectivity between units & components on the Processor.
What are the Uses of Cache a very high speed memory?
Cache is a high-speed memory device that is placed between a microprocessor and a system memory. A Microprocessor usually can process data at a much faster rate than what the system memory can provide. If this disparity isn't handled, we will end up with a microprocessor that's idling most of the time, because it has to wait on main system memory to provide the (or cosnume) data. With a cache, which could operate at a speed near the processor to shuttle data back and forth between processor and memory. Cache memory relies on a concept in computer science called locality of reference. This concept stipulates that when the processor accesses a piece of data, it is highly likely that it will access data that are also in the same locale in memory. A cache subsystem will fetch the requested data and those around to anticpate the next processor request.
What is the What is the maximum memory address space that the processor can access directly if it is connected to a 8 bit memory considering a hypothetical microprocessor generating a 8 bit address?
microprocessor can access 2^8 points which is 256 then we have 8 bit memory = 1 bytes then 1*256 =256 bytes
How does the microprocessor knows which operation to perform first read or write?
in any of the microprocessor include sequencer that sequencer send control signal to the memory and processor to do specific operation like read or write operation
Why is microcontroller needed?
A microprocessor cant work as a stand alone unit.to make it work we have to interface memory and input out devices and so the PCB of microprocessor based system will be larger.Microcontroller consists of processor,memory and peripherals on a single chip and so needs no interfacing.Microcontroller can be programmed for any specific task.
Which Intel microprocessor address 1t of memory?
There is no microprocessor with !t of address memory, only virtual memory. the firt one was the 80486.
What is the need of Instruction PointerIP in 8086 microprocessor?
The Instruction Pointer (IP) in an 8086 microprocessor contains the address of the next instruction to be executed. The processor uses IP to request memory data from the Bus Interface Unit, and then increments it by the size of the instruction.
Special high-speed memory built into the micro processor for the micro processors?
virtual memory
Why you using micro controller NoT micro processor?
Microcontroller have inbuilt memory, interrupts, etc. Which you will need to connect externally in microprocessor. Thus, Microcontroller is better than microprocessors
Need of interface in microprocessor?
the principle function of memory interfacing is to enable the microprocessor to read or write into a register of the memory chip
