GENERAL INFORMATION
1.1
INTRODUCTION
This manual describes operation, configuration and installation instructions for the
RAMiX,
PMC551
PCI Mezzanine Card (PMC). The PMC551 provides a high performance memory
subsystem on the PCI I/O bus. The PMC551 memory will respond with low bus overhead and
high determinism. These features can be critical in high performance data acquisition systems.
1.2
FEATURES
The PMC551 complies with the CMC specification for PCI Mezzanine Cards. As such, it will
directly connect to any Single Board Computer (SBC), or Expansion Card that supports PMC
modules. All initialization and functional configuration of the PMC551 is done automatically by
software. Features implemented on the PMC551 include:
•
High performance DRAM memory
•
All configuration via PCI initialization transactions.
•
Can sustain data transfer at full PCI bandwidth.
•
No retry on PCI read
•
Internal read ahead for zero wait state burst reads
