Latest Patents

One of his latest patents is titled "Microprocessor having a branch predictor using speculative branch registers." This invention describes a method and apparatus for speculatively providing a branch target address as specified by an impending branch operation. In this embodiment, a branch prediction unit is operable to pre-decode and pre-execute branch operations in a pipeline stage prior to the decoding and execution stages of a pipelined processor. The operations are performed via multiple instructions that are separately scheduled and executed. A first instruction specifies a branch target, while a second instruction indicates when the branch operation is to occur. Additionally, the branch prediction unit can pre-fetch instructions from a memory hierarchy into a local instruction memory device in response to pre-decoding a first instruction of a branch operation.

Another significant patent is "Optimized branch predictions for strongly predicted compiler branches." This microprocessor includes a branch prediction table with at least one branch entry. Each entry contains a prediction field to indicate whether a branch is predicted to be taken, along with a history register that stores relevant history information. The prediction table also features prediction update logic that updates the prediction field and history register, except when a branch is strongly predicted statically.
