New IDT Integrated Processor Boosts System Bandwidth Through On-Chip Ethernet, PCI Optimization, and DDR Memory

11/12/2002 - IDTTM (Integrated Device Technology), a leading communications IC company, expanded its InterpriseTM family with the introduction of the IDTTM InterpriseTM RC32438 integrated communications processor. The newest member of the IDT InterpriseTM PCI offering delivers enhanced system bandwidth to communications applications within the Enterprise and access market segments, including desktop/workgroup switches, gateways, wireless access points (WAPs) and virtual private network (VPN) equipment. The RC32438 InterpriseTM PCI integrated communications processor also serves as a platform for IDT to develop future products that target emerging market segments such as embedded security and converged gateways.

The company’s focus on boosting bandwidth is driven by the growing requirements for higher sustained data rates and increased processing of data passing through the system. For example, Layer-2 desktop switching platforms are starting to support gigabit Ethernet local area network (LAN) connections in addition to the 10/100 Mbps connections previously deployed, and are also starting to incorporate certain Layer-3 data processing functions. In addition to the increasing performance demands in the Ethernet switch arena, wireless access points in the Enterprise are evolving to dual-mode radios and higher throughput 802.11 standards, and Enterprise gateways are integrating security functionalities on-chip. The RC32438 device addresses these performance and market demands and offers a natural upgrade path for customers using other IDT InterpriseTM PCI processors, allowing them to create higher-performance systems while leveraging their existing application software.

The RC32438 integrated communications processor incorporates a 32-bit MIPS® CPU core with a double data rate (DDR) memory controller, a 32-bit version 2.2 peripheral component interconnect (PCI) controller and two on-chip Ethernet interfaces. Designers have a choice of popular embedded operating systems, including VxWorks® and Linux® and a broad selection of development tools that reduce project design cycles and improve time-to-market.

"Devices from the IDT InterpriseTM PCI family have established a leadership position as the control processors of choice for managed Layer-2 switching systems," said Phil Bourekas, vice president of the Internetworking Products Division at IDT. "Our RC32438 integrated communications processor offers an unprecedented combination of on-chip features, optimized system performance, third-party development tools, and cost-sensitivity. In addition, the device’s backward compatibility with existing products helps our customers preserve their investment in software and development tools for their next generation of systems, and enables a broader reach into emerging Enterprise applications."

On-Chip Peripherals Drive System Bandwidth
The IDT InterpriseTM RC32438 integrated communications processor includes several key design features that contribute to boosting system bandwidth. The integration of two Ethernet interfaces reduces the level of bus traffic on other shared external buses and frees up bandwidth for use by other peripherals, improving system bandwidth and reducing overall system cost. The PCI bus interface is an industry-standard interface with a broad range of supporting low-cost, networking, storage and graphics peripherals. The PCI bus controller on the IDT RC32438 device is optimized for bursting data and is designed to provide continuous bursting for sustained throughput. The RC32438 device also incorporates a DDR memory controller that provides system designers with higher memory bandwidth systems than SDRAM-based solutions. Uniquely, the device also includes logic that allows the monitoring of transactions on the IPBus, the on-chip bus that connects the majority of the I/O peripherals, providing customers an opportunity to tune the device to optimize performance for an individual system configuration.

"From the outset, our aim was to design a well-balanced embedded processor, capable of delivering the right combination of memory bandwidth, system performance and CPU processing, to address performance requirements of key systems and enable the provision of value-added services," said Ian Ferguson, strategic marketing manager for the Internetworking Products Division at IDT. "Our standpoint is that high-performance CPU cores are pointless if they cannot be fed, and high theoretical system bandwidth is meaningless if the CPU is not able to process the data quickly enough, so we ensured that our RC32438 integrated communications processor addresses both of these requirements."

Multiple General-Purpose Peripherals
The RC32438 processor also includes a local memory I/O controller, three general-purpose counter/timers, a ten channel DMA controller, an I2C bus controller, two serial ports, an interrupt controller, a general-purpose I/O controller, and a serial peripheral interface (SPI).

Broad Choice of Development Tools
The use of the 4KcTM CPU core from MIPS Technologies in the IDT InterpriseTM RC32438 integrated communications processor allows customers to select from a broad range of generic development tools, including compilers, in-circuit emulators and real-time operating systems. IDT is already providing optimized VxWorks and embedded Linux solutions for the 79EB438 evaluation platform to enable customers to benchmark or prototype application software ahead of the availability of their own hardware. The device is also supported by a diverse range of in-circuit emulator equipment compatible with the enhanced JTAG (EJTAG) interface to help speed hardware/software integration tasks.

Pricing and Availability
The IDT InterpriseTM RC32438 integrated communications processor is currently sampling with production quantities available in Q1CY03. Pricing for the devices starts at $25 in 10,000-unit quantities.
