PC104p4IP



PC/104+ card with 4 IP slots

If you want to use IndustryPack® modules with your PC104p or PCI-104 system, the PC104p4IP is the choice for you. The PC104p4IP combines features you need with simplicity and speed. Up to 4 IP modules can be installed. Standard 16 bit IPs plus 32 bit, and double wide modules fit right in. Each slot has independent operation - control, clocking, IO, power filtering and protection. The PC104p4IP is highly integrated with the PCI and IP interfaces closely coupled within the same FPGA. As a result the PC104p4IP is faster, has a higher MTBF, and is easier to use than competing designs. There are fewer initialization steps and fewer PCI addresses to deal with and yet there are more features to work with. With the Windows®XP/2000 driver; operation can be "plug and play". Linux is available too.

Our customers are our best source of feed-back and new ideas to implement. The PC104p4IP is now revision B for the PROM. The Revision B PROM has added support for the Dynamic Engineering Carrier Driver; Added interrupt status within each slot control register. Revision A featured Byte and Word Swapping, Bus error status for each slot independently, and 32 IP support. Shipping now. If you have PC104p4IPs and want to update to the latest firmware we have a PROM update program. A minimal cost of $25 for the first updated PROM. Please provide your serial number(s) to be updated along with your PO.

Multi-board operation is supported. With multiple PC104p4IP´s in your system and unique cabling, sensors etc. for each slot on each PC104p4IP it is important to "know" which PC104p4IP is which, and to properly control the IP modules mounted to them. A surface mount "dip switch" is provided to create an identifier for the software. A specific PC104p4IP can be matched with the PCI address allocated for deterministic control. The switch can also be used for other purposes; configuration control or debugging for example. The switch values are available to be read via the PCI bus.

Each slot has a separate clock controller for 8 and 32 MHz operation. The clocks are locked together for the four slots plus the state-machine. Glitch free operation means the frequency can be be changed on the fly. Series and parallel terminations with equal length traces insure clean clocks and coherant operation across the 4 IPs and the controlling state-machine. A well designed clock distribution is critical for reliable operation.

Each slot has resettable "self healing" fused filtered power. +5, +12, and -12V supported.

Industry standard 50 pin [ribbon cable] headers are used with the IO connectors. Vertical connectors are provided in all positions. Ribbon cable or discrete wire cables can be interfaced directly with the PC104p4IP. The traces between the IP IO connector and the PC104pIP IO connector have matched length [within .002"] for each slot independently. Slots B and D, C and E have similar lengths. The HDRterm50 can be used to create a terminal block interface.

Slots B/C and D/E are configured to accept two single IPs, or a double wide Industrypack compatible design. The data bus is designed to allow for 32 bit IP Bus operation. The data bus width is controlled by the address range the slot is controlled with. Automatic switching makes it possible to switch data bus size without changing the control registers for seamless operation.

Three methods of resetting the IPs are built into the PC104p4IP. A local pushbutton reset switch is provided. The IPs can be reset from the control register within the FPGA via the software interface. The IPs are reset on power-up via a supervisory circuit that guarantees the 200 mS minimum reset requirement in the IP specification. The resets only affects the IP slots.

LEDs are provided to each of the four IP slots for activity indicators. When each slot is accessed the LED is flashed. The Xilinx provides a "one shot" circuit to stretch the "on" time to make it visable. Power indicator LEDs [3] are provided. An additional eight user LEDs are available for debugging or other purposes.

IndustryPacks are usually 16 bit devices and the PCI bus supports 32 bits. The PC104p4IP accepts 32 bit PCI accesses and converts them into two 16 bit accesses with an auto-incremented or static address. One PCI access can be used to write to or read from two IP locations or twice to one location. Byte, Word and Long Word accesses are supported to the 16 and 32 bit IP sites from the PCI bus. If a 32 bit IP has been installed then direct 32 bit operation can be utilized.

The IP accesses are protected by a watch-dog timer. The timer is started at the beginning of each IP access. If the timer expires before the IP being accessed responds, a bus error internal to the PC104p4IP is created. The PC104p4IP responds normally to the host, not tying up the PCI bus, and provides status and an optional interrupt to alert the host to the problem with the IP. The Bus Error timer is useful in situations where the software may want to cause a bus error to find out what is installed or where a hung system would have consequences. Multi-threaded software operation is supported with separate bus error status in each of the slot control registers.

The PCI bus is defined as little endian and many IPs have their register sets defined to operate efficiently with a little endian interface. The default settings on the PC104p4IP are "straight through" byte for byte and D15-0 written to address 0x00 before D31-D16 written to address 0x02 when long words are written to 16 bit ports. Please note that any long word address can be used. The lower data is written to the lower address first, then the upper data to the upper address. Each slot has a ByteSwap and WordSwap control bit to allow Byte and Word Swapping to be performed to accommodate alternate IP and OS requirements.

Connector positioning is compatible with IP-Debug-Bus to allow the user to isolate and debug the control interface of an IP. The IP-Debug-IO can be used in conjunction with the PC104p4IP and IP-Debug-Bus to provide test-points on the IO signals and loop-back capability for the IP.
