i960 RP PROCESSOR:
COMPLETE I/O SUBSYSTEM ON A CHIP
The i960 RP processor,integrating an i960 Jx processor core, a PCI-to-PCI bridge, memory controller, and other peripherals, provides servers with the ability to balance I/O requirements with application processing demands. By offloading the I/O processing to the i960 RP processor, servers can achieve higher I/O throughput at a much lower host CPU utilization – improving overall server performance.

IQ-SDK FEATURES AND BENEFITS

• Complete PCI Intelligent I/O software development platform
• Development environment for the i960® RP processor, a single-chip intelligent I/O subsystem. The i960 RP processor integrates an i960 Jx processor with a compliant PCI-to-PCI bridge, memory controller and other peripherals.
• IxWorks I2O-compatible Real Time Operating System by Wind River Systems (License included with processor)
• Interchangeable IQ I/O modules with multiple expansion interfaces, including, SCSI/Fast Ethernet, ATM/Fast Ethernet, Fibre Channel, and PCI extender
• Developers can custom design IQ I/O modules
• Product manuals, documentation, and a getting started guide to enhance the kit's ease-of-use
• CTOOLS Cross Development Toolset, with profile-driver compiler, assembler, linker, libraries, debugger, monitor, and utilities. DOS and Windows 95 host environments available.
• Fast download across the PCI backplane; debug and download through the serial port
• PLD equations and schematics are easily available via bulletin board service
• Full length PCI add-in card format
• 32 pin PLCC Flash ROM/EPROM sockets
• Serial console ports
• 2 MB Interleaved DRAM, expandable to 64 MB
• Secondary PCI bus expansion connector with clock and arbitration signals for up to 4 PCI master devices
• 512 Kbytes serial EEPROM connected to the i960 RP processor I2C Bus Port
• APIC bus header, Emulator header, and JTAG Header

The basic objective of the I2O specification is to provide an I/O architecture in which the device driver is independent of the host architecture and operating system. The I2O specification will facilitate intelligent I/O subsystems through support for message-passing between multiple independent processors. This open,standards-based approach enables a new generation of portable intelligent I/O solutions.

SOFTWARE DEVELOPMENT SUPPORT
For ease-of-use, the IQ-SDK platform mimics the current Intel PCI I/O Software Development Kit (PCI-SDK). The platform includes a complete set of software development tools and related documentation, including Intel's CTOOLS profile-driven compiler,assembler, linker, libraries, debugger, monitor, and utilities. The compiler provides code execution profiling and instruction scheduling optimizations for the i960 RP microprocessor. Profiling capability reduces tuning effort by as much as 75% by minimizing the need to write hand-tuned assembly code. It also increases code performance by an average of 25%.

In addition, the kit includes IxWorks, an I2O compatible RTOS developed by Wind River Systems. IxWorks provides a powerful,general-purpose real-time operating system that has clearly defined application program interfaces (APIs). All of this creates a user-friendly environment to rapidly develop basic device drivers,support NOS-to-driver independence, and allow multiple I/O software to coexist.

IQ I/O INTERFACE MODULES
The IQ I/O Interface Modules are PCI daughtercards which interface to the secondary PCI bus of the i960 RP processor. IQ I/O Interface Modules available include:

• Dual SCSI/Dual Fast Ethernet (included in kit)
• Fast Ethernet/ATM (optional)
• PCI extender – Three standard PCI expansion slots

These cards will greatly reduce the development time of software applications for I/O interfaces by providing a software target. The developer will also have the option on designing a custom IQ I/O Interface Module with the documentation and support provided by Intel.
