PAGE REQUEST INTERFACE SUPPORT IN CACHING HOST MEMORY ADDRESS TRANSLATION DATA IN A MEMORY SUB-SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18505302 titled 'PAGE REQUEST INTERFACE SUPPORT IN CACHING HOST MEMORY ADDRESS TRANSLATION DATA IN A MEMORY SUB-SYSTEM
Simplified Explanation
The processing device described in the patent application includes host interface circuitry and an address translation circuit with a cache for storing address translations. A page request interface (PRI) handler manages translation miss messages from the host interface circuits, creating page miss requests and queuing them for a translation agent of the host system.
- Host interface circuitry interacts with a host system
- Address translation circuit handles address translation requests
- Cache stores address translations for future access
- PRI handler tracks translation miss messages and creates page miss requests
- Page miss requests are categorized into page request groups for each host interface circuit
- Page request groups are queued for a translation agent of the host system
Potential Applications
This technology could be applied in:
- Memory management systems
- Virtualization software
- Network routers

Original Abstract Submitted
A processing device includes host interface circuitry to interact with a host system and an address translation circuit to handle address translation requests to the host system from host interface circuits. The address translation circuit includes a cache to store address translations associated with the address translation requests for future access by host interface circuits. A page request interface (PRI) handler tracks translation miss messages received from the host interface circuits, each translation miss message including a virtual address of a miss at the cache. The PRI handler removes duplicate translation miss messages having an identical virtual address and creates page miss requests from non-duplicate translation miss messages that are categorized into page request groups, each page request group corresponding to a host interface circuit of the host interface circuits. The PRI handler queues the page request groups to be sent to a translation agent of the host system.
