4.1 MMI - Main Memory Interface

PNX15xx Series has an unified memory system for the PNX15xx Series CPU and all
of its modules. This memory is also visible from any PCI master as PCI attached
memory.
The 32-bit DDR SDRAM interface can operate up to 200 MHz. This is equivalent to a
64-bit SDR SDRAM interface running at 200 MHz, resulting in theoretical available
bandwidth of up to 1.6 GB/s.
This interface can support memory footprints from 8 up to 256 MB. The supported
memory configurations are displayed in
The memory interface also performs the arbitration of the internal memory bus,
guaranteeing adequate bandwidth and latency to the TM3260 CPU, DMA devices
and other internal resources that require memory access. A programmable list-based
memory arbitration scheme is used to customize the memory bandwidth usage of
various hardware modules for a given application. The CPU in the system is given the
ability to intersect long DMA transfers, up to a programmable number of times per
interval. This allows optimal CPU performance at high DDR DMA utilization rate, and
guarantees the real-time needs of audio/video DMA modules.
The memory controller supports most, if not all, DDR SDRAM devices thanks to
programmable memory timing parameters. For example CAS latency, T
and many others can be programmed after the default boot initialization.
NAND and NOR type flash memory connects to the PNX15xx Series by sharing
some PCI bus pins. The XIO bus created by this pin-sharing supports 8- and 16-bit
data peripherals, and uses a few side-band control signals. Refer to
on page 2-24
for more details.
