Discovery™ III System Controllers

The Marvell Discovery™ III family of system controllers for MIPS and PowerPC processor-based subsystems are Marvell's most advanced, highest performing system controllers to date. These new system controllers build upon Marvell's industry-standard Discovery platform and establish new benchmarks for performance and integration-making Discovery III system controllers the industry's most powerful controllers. Offering an innovative crossbar architecture, advanced communications peripherals and performance tuned interfaces, the Discovery III system controllers enable system designers to build high-performance, scalable systems.

The Marvell Discovery III MV64440, MV64441 and MV64442 devices are designed for 64-bit MIPS microprocessors such as the PMC-Sierra™ RM7000A/B/C and RM9000 processors. These devices support MIPS processor's traditional SysAD bus, as well as extended PMC-Sierra MIPS bus protocols up to 200 MHz - for maximum processor-to-peripheral communications bandwidth.

The Marvell Discovery III MV64460, MV6461 and MV6462 devices are designed for PowerPC processors such as the Motorola MPC74xx and MPC75x families and the IBM 750CXe/FX /GX series CPUs.  These devices support PowerPC processors and both the 60x and the advanced Motorola MPX bus protocols. The Marvell Discovery III MV6446x devices also support Symmetrical Multi-Processing (SMP) in both 60x and MPX modes, enabling highest processor performance.

With a suite of six devices offering a rich feature mix, the Discovery III system controllers are ideally suited for a broad application range, from demanding networking applications such as core routers and wireless base stations to high volume embedded markets such as laser printers and storage networking applications.  With its dual PCI-X and multiple Gigabit Ethernet (GbE) interfaces, the Discovery III devices enable Fibre Channel, iSCSI and Serial ATA storage applications.

Revolutionary Architecture, Advanced Features

The Marvell Discovery III devices feature an advanced high-performance crossbar switch architecture with any-to-any connectivity. With up to 100 Gigabits per second (Gbps) of aggregate throughput, the crossbar fabric supports non-blocking concurrent connections among peripherals at full bus speeds, delivering break-through performance for advanced Internet infrastructure equipment.

The Discovery IIII system controllers are highly integrated and offer leading-edge peripherals on-chip, including up to three GbE Media Access Controllers (MACs), up to two PCI-X interfaces and DDR memory support. In addition, some Discovery III devices offer an integrated 2 Megabits of cache coherent SRAM that resides on the processor interface unit to provide low latency storage for descriptors, packets, etc.

All Discovery III system controllers are software compatible with other Discovery III devices as well as with other leading Marvell system controller products, offering significant time-to-market time savings and reduced risk.
