His work focuses on enhancing the efficiency and performance of microprocessors through innovative methods and apparatuses.
Latest Patents
One of his latest patents is a method and apparatus for implementing a set-associative branch target. This invention involves a Branch Target Buffer Circuit in a computer processor that predicts branch instructions using a stream of computer instructions. The Branch Target Buffer Circuit utilizes a Branch Target Buffer Cache to store information about previously executed branch instructions. It addresses the branch information stored in the cache by the last byte of each branch instruction. When an Instruction Fetch Unit fetches a block of instructions, it sends an instruction pointer to the Branch Target Buffer Circuit. The circuit then checks the cache to identify any branch instructions in the fetched block. If an upcoming branch instruction is found, the circuit informs the Instruction Fetch Unit accordingly.
Another notable patent by Natarajan is for a branch instruction pointer table. This invention employs a buffer to store information about branch instructions within a pipelined microprocessor capable of speculative execution. When a branch instruction is decoded, the address of the instruction following it, known as the Next Linear Instruction Pointer (NLIP), along with processor state information, is recorded in a Branch Instruction Pointer Table. The branch instruction then continues through the microprocessor pipeline until execution. The resolved outcome of the branch instruction is compared with the predicted outcome. If the prediction is correct, execution continues along the current path. If incorrect, the execution unit flushes the pipeline and restores the microprocessor state from the Branch IP Table.
