Translation Lookaside Buffer
Prefetch Buffer
Branch Target Buffer
A buffer that translates the logical address to physical address.
Translation Lookaside Buffer
A buffer that prefetches the next 32 bytes instruction code.
Prefetch Buffer
A buffer that copies the instructions in different part of program located at branch target.
