A method and system for storing instructions retrieved from memory in a memory
cache to provide said instructions to a processor. First a new instruction is received
from the memory. The system then determines whether the new instruction is a start
of a basic block of instructions. If the new instruction is the start of a basic
block of instructions, the system determines whether the basic block of instructions
is stored in the memory cache responsive. If the basic block of instructions is
not stored in the memory cache, the system retrieves the basic block of instructions
for the new instruction from the memory. The system then stores the basic block
of instructions in a buffer. The system then predicts a next basic block of instructions
needed by the processor from the basic block of instructions. The system determines
whether the next block of instructions is stored in the cache memory and retrieves
the next basic block of instructions from the memory if the next block of instructions
is not stored in memory.
