Mets IOP332 I/O Processor with Intel XScale® Microarchitecture

Mets IOP332 I/O Processor with Intel XScale® Microarchitecture 

■ 32-bit high-performance CPU (500, 667, 800MHz) based upon Intel XScale® microarchitecture

■ Integrated PCI Express to PCI-X Bridge (PCIExpress 1.0A compliant and PCI-X 1.0A, PCI2.3, compliant), B-segment provides PCI-X bussegment via transparent bridge for motherboardslots or devices and also supports PCI-X Hot Plug

■ Double Rate Data (DDR) 333 and DDR2-400SDRAM with ECC (up to 2 GB of 32-or 64-bitmemory, optional single-bit error correction/multibit detection support)

■ Enhanced memory controller with pipelinedaccess from the Intel XScale core to internalperipherals (programmable control for preemptionby the Intel XScale core and a multi-transactioncounter for performance tuning)

■ RAID5 XOR and iSCSI CRC32C off-load engines

■ 8-/16-bit, 66 MHz Peripheral Bus Interface(programmable bus width and wait states fortwo memory windows, two chip selects)

■ 266 MHz, 64-bit (up to 2.1 GB/sec) internal bus 

■ 2-channel DMA engine with support for scatterand gather of data blocks, automatic datachaining, and unaligned data transfers betweenPCI-to-local memory, local memory-to-PCI andmemory-to-memory (three 1 Kbyte data buffersper channel)

■ Up to 17 external interrupt inputs to the Interrupt Controller support vector generationand four priority levels

■ Two 16550-compatible UARTs (4-pin,Master/Slave capable, 64-byte Receive/Transmit FIFOs)

■ Eight GPIO pins that can also be used asexternal interrupt pins

■ Two industry-standard-based I2C interfaces

■ SM Bus support

■ Two programmable 32-bit Timers and Watchdog Timer

■ Typical power consumption is less than 10 Watts (500 MHz)

■ 829-ball FCBGA (37.5 mm2)Product OverviewHigh-Performance, I/O Processor Based on Intel XScale® TechnologyThe Intel® IOP332 is a highly integrated I/O system on a chip for RAID on Motherboard and I/O-intensive storage, networking andcommunicationsapplications. The IOP332features an 800 MHz CPU, high-performanceinternal bus, enhanced memory controller, high-bandwidth PCI Express to PCI-X Bridge, and an improved interrupt controller to provide a high-performance, highlyintegratedprocessorsolution. Target applications include RAID onMotherboard and PCI Express host-basedadapters (RAID cards, iSCSI cards, FC cards,Security SSL NICs, etc.), and a host of otherintelligent I/O applications that require a highlyintegrated, high-performance system on a chipprocessor with an integrated PCI Express interface.
