| The
PCI-7300A is PCI form factor ultra-high speed
digital I/O card; it consists of 32 digital input
and/or output channel. High performance designs and
the state-of-the-art technology make this card to be
ideal for high-speed digital input and output
applications. |
| Bus
Mastering DMA |
| The
PCI-7300A performs high-speed data transfers using
bus mastering DMA and scatter gather via 32-bit PCI
bus architecture. The maximum data transfer rates
can be up to 40MB per second. PCI bus greatly
extends data throughput up to 132M bytes/sec and
also has provisions for processor-free DMA (direct
memory access). While the PCI-7300A becomes the bus
master, it takes control of the PCI bus, transfers
data at burst speed, then releases the bus for other
peripheral use. |
| Scatter
Gather Hardware Support |
| For
bus master devices, this says that the hardware has
some sort of built-in support for transferring data
to and from noncontiguous ranged of physical memory.
The PCI-7300A contains multiple pairs of address and
length registers, each one describing a single
contiguous buffer segment. This allows PCI-7300A to
perform I/O using buffers that are scattered
throughout DMA address space. These multiple address
and count registers are often referred to as a scatter/gather
list, but you can also think of these bus
masters as having their own built-in mapping
registers. |
| I/O
Port Configurations |
| The
PCI-7300A is configured as two ports, PORTA and
PORTB; each port controls 16 digital I/O lines. The
I/O can configure as either input or output, and
8-bit or 16-bit. According to outside device
environment, users can configure PCI-7300A to meet
all high-speed digital I/O data transferring.
PCI-7300A can support many different digital I/O
operation modes: |
| Internal
Clock: the digital input and output
operations are handled by internal clock and
transferred by bus mastering DMA. |
| External
Trigger: the digital input and output
operations are handled by external In/Out strobe
signal (DI_REQ and DO_ACK) and transferred by bus
mastering DMA. |
| Handshaking:
through REQ input signal and ACK output signal,
the digital I/O data can have simple handshaking
data transfer. |
| Pattern
Generation: reading or writing digital
data a predetermined rate. Users can control this
rate internally by on-board counters with timing
resolution 50 ns. |
