Intel's i960® processor family is one of the broadest and most well-supported lines of 32-bit embedded microprocessors available. If you look inside some of the computer industry's most innovative products - rapid, high-resolution printers, high-speed networking equipment, or Intelligent I/O for subsystems-you are likely to find an i960 processor driving the application. All members of the family share a common core architecture and newer members of the family are upwards-compatible with existing versions, so your software investment is always protected. The Solutions960(r) program brings together some of the most innovative tools suppliers in the industry so you can choose the right development tools to fit your needs and get you to market fast. And we even make it easy to determine which processor to choose: our common base evaluation board allows you to swap processor modules so you can run benchmarks on different processor versions without breaking your budget buying a stack of boards. Our Quikval evaluation kits also include sample code to get you started, a C compiler and demo copies of development tools for you to test drive. Intelligent I/O ProcessorThe newest member of the i960 processor family, the 80960RP, is also the first product in a new line of Intelligent I/O processors from Intel known as the IQ Series. This highly integrated processor incorporates a complete PCI-based I/O subsystem including a DMA controller, memory controller, I2C interface, APIC interface, and a PCI-to-PCI bridge. The i960RP processor enables you to boost system throughput in servers by relieving the host CPU from the task of servicing I/O interrupts from attached peripheral devices such as storage systems and networking controllers. I2O Software Specification Industry leaders recently agreed upon a common specification for writing device drivers for computer systems that is independent of operating system and hardware. Companies that choose the I2O software specification will no longer need to struggle to write and obtain certification for every operating system on the market, but can write a single driver for them all. The i960RP processor is unique in that it includes a hardware messaging interface designed to support the I2O specification and ensure that the host CPU and I/O subsystems can communicate efficiently. To simplify the development task even further, every i960RP processor purchased includes a run-time license for Wind River Systems' IxWorks. This real-time operating system provides the object-oriented API called for in the I2O software specification and a comprehensive set of OS services, so that hardware developers only have to concern themselves with writing a device driver. Networking and Imaging Solutions If you design products for networking, imaging, or other high-performance embedded applications, then you will be interested in evaluating the superscalar members of the i960 processor family: the CA, CF, HA, HD and HT. Each of these processors is capable of executing multiple instructions in a single clock cycle and include features designed to boost performance, including large caches, 128-bit wide internal data paths, and high-bandwidth, non-multiplexed burst buses. Since limiting system clock speeds is often a concern for designers of embedded systems who can't afford to use SRAM in their systems, the H-series makes full use of Intel's clock-doubling and clock-tripling technology to deliver the advantages of high-speed processing while keeping the demand on memory systems in check. Balancing System Cost and Performance For mid-range designs, the J-series of i960 processors may be the perfect choice. The design of these scalar processors carefully balances performance with system cost. The caches are smaller than the superscalar members of the family and each of the J-series processors use a multiplexed bus. Advantages include lower power utilization, smaller board space requirements, and lower overall system implementation cost. The i960JA and i960JF processors offer the designer a choice in instruction and data cache size, while the i960JD processor uses clock doubling technology to boost processor performance while keeping memory bus speeds low. Upgrading to 32-bit RISC If you're seeking to upgrade your aging 16-bit design to 32-bit performance, but still have some tough cost constraints, perhaps you should consider moving up to the entry-level members of the i960 processor family. For under $10 (US suggested retail), the i960SA processor offers a full 32-bit internal RISC architecture with an on-chip interrupt controller and a multiplexed 16-bit external bus with burst operation to keep costs low. For higher throughput, the i960KA processor adds a 32-bit external bus. If floating-point performance is a consideration in your design, the i960SB and i960KB processor are worth a look. These two processors, found in many of the world's most popular video arcade games, include complete IEEE-compliant floating-point units on chip. Please take some time and explore the many members of the i960 processor family. You will find complete data sheets on this web site along with application notes and other technical documents to help you learn more.
