METHOD AND APPARATUS FOR PERFORMING JUMP OPERATIONS IN A DIGITAL PROCESSOR |
摘要 |
<p>Methods and apparatus are provided for performing a jump operation in a pipelined digital processor. The method includes writing target addresses of jump instructions to be executed to a memory table, detecting a first jump instruction being executed by the processor, the first jump instruction referencing a pointer to a first target address in the memory table, the processor executing the first jump instruction by jumping to the first target address and modifying the pointer to point to a second target address in the memory table, the second target address corresponding to a second jump instruction. The execution of the first jump instruction may include prefetching at least one future target address from the memory table and writing the future target address in a local memory. The second target address may be accessed in the local memory in response to detection of the second jump instruction.</p> |
