New core logic products from Galileo Technology set new standards for embedded system price/performance levels; new high-integration chipset products lets designers build 133 MIPS+ embedded systems for under $75.

SAN JOSE, Calif.--(BUSINESS WIRE)--April 14, 1997--Galileo Technology announced today two new core logic chips, the GT-64011 and GT-64014, for the high-performance/low-cost IDT/MIPS RV4640 and RV4650 processors. Both of these new products from Galileo provide an EDO DRAM controller, 4 channels of DMA, and a complete device controller; the GT-64011 also supports a high bandwidth PCI master/slave interface.

"RISC processors such as IDT's RV4640 and RV4650 offer tremendous performance capabilities for demanding applications such as data communications, telecommunications, and digital video distribution," stated Mitch Kahn, Galileo's vice president of marketing. "These processors, in combination with Galileo's new core logic products, the GT-64011 or GT-64014, provide embedded system designers with a powerful set of bus interface and device control capabilities at a remarkably low cost."

Galileo's director of product marketing, Barry Gray added: "Embedded systems are differentiated using powerful system software and hardware functionality to enable leading edge features. The key is to provide these advanced features at price points which drive market demand. The combination of Galileo's core logic and IDT's RISC processors enables more than 133 MIPS performance at component costs of less than $75. Previous solutions required resource-consuming ASIC development and/or several components whose high cost prohibited mass market acceptance."

Extensive Feature Set

The GT-64011 has a three-bus architecture, and the GT-64014 supports two busses. Both provide a 32-bit interface to the CPU and a 32-bit interface to memory and device subsystems; the GT-64011 also supports a 32-bit PCI interface. The three buses are de-coupled from each other for most accesses, enabling concurrent operation of the CPU, PCI I/O, and accesses to memory. The CPU interface supports bus frequencies up to 50MHz, while the processor can operate at internal clock rates up to 200 MHz.

Both the GT-64011 and GT-64014 provide a flexible DRAM memory controller that supports EDO as a well as page mode DRAMs. Memory can be addressed up to 512MB, separated in up to 4 independent banks. Other types of memory devices may also be used including flash, EPROM, SRAM, and FIFOs. The 64011 and 64014 also incorporate four high-performance DMA engines. The DMA channels can be programmed by the CPU or by PCI bus masters, or without CPU intervention via a linked record list.

The PCI interface on the GT-64011 is fully compliant with both PCI 2.1 and Plug & Play standards. The GT-64011's PCI controller becomes a master whenever the CPU or internal DMA engine initiates a PCI bus cycle. These cycles can be Memory, Interrupt Acknowledge, Special, I/O, or Configuration cycles.

Typical Applications

The GT-64011 is an ideal choice for PCI-based data communications systems. Galileo's core logic is currently designed into applications such as Cisco 7200-series routers and Ethernet and Fast Ethernet switches using Galileo integrated switch chips such as the GT-48001A and the GT-48002. High-performance PCI add-in cards, such as those used in WAN remote access servers, also use the GT-46011 as a glue-less interface between the local protocol processor and main CPU.

Evaluation and Development Tools

The Galileo-9 PCI Evaluation Board is available for customers to prototype and develop software for the GT-64011 and GT-64014. Galileo-9 is a full-size PCI add-in card with a 100MHz R4640 processor, four DRAM SIMM slots, 2 Mbytes of Flash memory, and a 1 Mbyte EPROM. Headers are available for interfacing custom logic. Galileo-9 can be used in any PCI based workstation, or plugged into the optional Galileo-4PB passive PCI backplane. Schematics of all Galileo evaluation platforms are available on Galileo's website.

Price and Availability

Samples of the GT-64011 and GT-64014 are available now and both devices will be in production during the second quarter of 1997. Pricing for the GT-64011 is $24.95 and the GT-64014 is $19.95; both in 10K unit quantities.
