CP3-HOUSE * Dual-Slot PC Card Host Adapter
|
The PC Card specification defines three card sizes (3.3/5.0/10.5mm thick),
referred to as type I...III. Type I typically can be found with memory cards,
and type II with I/O products such as wireless LAN or networking adapters. Type
III often will be used with ATA hard disks.
The dual slot of the CP3-HOUSE accepts two PC Cards of the type I/II,
or a single type III PC Card.
The PC Card represents a flexible method for external system expansion,
without any need to open the case, or power down and reboot the whole system.
While the 32-bit CardBus PC Card is equivalent to a modern PCI slot board,
the 16-bit PCMCIA PC Card could be loosely compared to a vintage ISA slot board.

The CP3-HOUSE recognizes automatically the PC Card type in use and configures
itself for PCMCIA or CardBus operation dynamically. Mix and match operation
of 5V/3.3V 16-bit PCMCIA cards and 3.3V CardBus cards is guaranteed. When
serving 32-bit PC Cards (CardBus), the CP3-HOUSE acts as a PCI bridge.
This allows direct access to the PC Card by the host CPU. Vice versa CardBus
cards can become DMA bus masters in order to transfer data at full 133MBps
bandwidth across the PCI system bus.
The CP3-HOUSE therefore is well-suited as universal system expansion port,
be it I/O function PC Cards, or as an easy way for saving data to a removable
memory card or disk drive.

CP3-HOUSE * Block Diagram
|
The CP3-HOUSE is equipped with the popular PCI1420 (Texas Instruments)
controller chip. Among other features, Hot Insertion and Removal and the
Exchangeable Card Architecture (ExCA) are supported by the PCI1420. Both
PCI1420 PC Card device drivers, PCMCIA and CardBus, are already integral
parts of current Windows operating systems.
Slot Vcc and Vpp are controlled by the programmable power switch TPS2224,
including over-current protection. Green LEDs in the front panel adjacent
to each slot indicate the present slot power status. Yellow LED's signal the
PC Card activity.
In order to use the CP3-HOUSE in 6U systems, a front panel expansion kit is
additionally available (CR9-ADAPT).
Optionally, the board is provided with a Zoomed Video (ZV) connector. ZV, as
an extension to the PC Card standard, is a fast one-way data path from a ZV
card to any ZV compliant display controller. ZV allows for real-time,
uninterrupted full frame-rate (live video) display, without charging the
PCI system bus or spending CPU calculation time. PCM audio data can be derived
from the optional Zoomed Video Audio (ZVA) connector.
PC Cards with built-in audio function, e.g. Modem cards, profit from the
optional on-board miniature speaker of the CP3-HOUSE.

When older software (legacy drivers) is in use, especially in combination with
16-bit PCMCIA I/O cards (e.g. Modem cards), ISA interrupts may be activated.
However, due to restrictions of the CPCI bus specification, the CP3-HOUSE is
capable of routing PC Card interrupts to the CompactPCI bus interrupt lines
INTA and INTP/INTS only. The CPCI bus does not at all support legacy ISA
interrupts (with the exception of the primary/secondary IDE IRQ14/15, which
can be optionally processed as INTP/INTS). A solution to this limitation is
to transfer serialized ISA interrupts across INTS to the host CPU, which
requires that the CPU board can be configured for receiving serial IRQs. ISA
service requests typically are caused by legacy software drivers for 16-bit
(PCMCIA) I/O PC Cards. When using recent drivers, serialized ISA IRQ jumpering
should be superfluous. This also applies for most PCMCIA memory cards, ATA
harddisks, and CardBus products.
Due to the huge variety of PC Card products available, often 16-bit (low cost)
PCMCIA products, potential conflicts between PC Card application software, the
operating system and the system BIOS can arise. In addition, CPCI systems use
a PCI bridge to isolate the backplane from the primary (host) PCI bus.
Stipulated for CPCI passive backplanes, this is an important improvement
in reliability, but not typical for desktop- and notebook-computers. As
it appears, this feature remains untested sometimes by the producers of
software. However, at least the manufacturers of BIOS software seem to be
aware of the emerging role of CPCI systems and PCI bridges, and have
eliminated most of the related bugs. If in doubt, use recent software/drivers
only and consider a CPU BIOS upgrade.
