Abstract: According to various aspects, a memory management unit (MMU) having multiple parallel translation machines may collect transactions in an incoming transaction stream and select appropriate transactions to dispatch to the parallel translation machines. For example, the MMU may include a dispatcher that can identify different transactions that belong to the same address set (e.g., have the same address translation) and dispatch one transaction from each transaction set to an individual translation machine. As such, the dispatcher may be used to ensure that multiple parallel translation machines do not perform identical memory translations, as other transactions that share the same address translation may obtain the translation results from a translation lookaside buffer.
