Memory Banks
A memory bank is a specific region of memory that the processor has direct access to. It is a collection of memory addresses that the processor can read from or write to directly, without involving other parts of the system.
Characteristics of Memory Banks:
Each memory bank has a unique address space.
A memory bank can contain up to 8K bytes of memory.
Different memory banks can be used for different purposes, such as instruction memory, data memory, and stack memory.
Example:
Consider a 4K-byte memory bank named "data_mem". This means that the processor can access memory addresses starting from 0x0000 to 0x0003.
Benefits of Using Memory Banks:
Performance: Memory banks allow the processor to access memory faster than if it had to access it through other memory locations.
Efficiency: By dividing memory into different banks, the processor can use the memory that is most actively used.
Flexibility: Memory banks can be easily expanded or contracted to meet changing memory requirements.
Examples of Memory Banks:
Instruction memory: Stores instructions that are executed by the processor.
Data memory: Stores data that is used by the processor.
Stack memory: Used by the compiler and run-time environment.
Additional Notes:
Memory banks are often divided into multiple banks of different sizes.
Each memory bank has a control register that specifies which bank is currently active.
Memory banks are a powerful technique that can significantly improve the performance of a processor
