9080/V830
V830 Application
Note Features
Complete Application Note designing adapter embedded system based V830 processor including: Detailed Design Description OrCad Schematics Verilog Source Code Superior performance based 9080 master interface chip which supports: burst master, slave cycles configuration cycles Asynchronous PCI/ V830 operation I2OMessaging Unit Combined with PLX's I2OSDK® provides powerful tool developing V830-based
General Description
This application note describes interface V830 using 9080 "PCI Local Bridge" information used build either adapter embedded system. 9080 Direct Master, Direct Slave data transfer capabilities. Direct Master mode allows device (V830) Local perform memory, I/O, configuration cycles bus. Direct Slave gives master device ability access memory Local Bus. 9080 allows Local asynchronously through bi-directional FIFOs.

9080 Overview
Features
Version compliant Master Interface chip adapters embedded systems Compatible Messaging Unit Volt signaling, volt core, low-power CMOS 208-pin PQFP independent channels local memory to/from host data transfers Eight programmable FIFOs zero wait state burst operation Local data transfers MB/sec Programmable local supports nonmultiplexed 32-bit address/data, multiplexed bit, slave accesses local devices Local runs asynchronously Eight mailbox doorbell registers Performs Endian/Little Endian conversion Upward compatibility with 9060/9060ES/9060SD (See compatibility notes)
General Description
9080 provides compact, high performance master interface adapter boards embedded systems. programmable local chip configured directly connect wide variety processors, controllers memory subsystems. 9080 contains Intelligent (I2O) messaging unit that allows high performance compatible software implementations protocol specification. Users 9060, 9060ES 9060SD chips upgrade their products support I2O, Volts other features with little change existing hardware software. 9080 provides independent chaining channels with bi-directional FIFOs supporting zero wait state burst transfers between host local memory. Slave transfers performed through third FIFO. fourth FIFO allows local processor other controllers perform direct master transfers bus. 9080 also allows local processor configure other devices system
