 Fast Memory Access (Intel
®
 FMA)
Just-in-Time Command Scheduling
The system memory controller has an advanced command scheduler where all
pending requests are examined simultaneously to determine the most efficient request
to be issued next. The most efficient request is picked from all pending requests and
issued to system memory Just-in-Time to make optimal use of Command Overlapping.
Thus, instead of having all memory access requests go individually through an
arbitration mechanism forcing requests to be executed one at a time, the requests can
be started without interfering with the current request, allowing for concurrent issuing
of requests. This allows for optimized bandwidth and reduced latency while
maintaining appropriate command spacing to meet system memory protocol.
Command Overlap
Command Overlap allows the insertion of the DRAM commands between the Activate,
Pre-charge, and Read/Write commands normally used, as long as the inserted
commands do not affect the currently executing command. Multiple commands can be
issued in an overlapping manner, increasing the efficiency of system memory protocol.
