Functional Description
Introduction
Micrel's KS8695P, member CENTAUR line integrated processors, high-performance router-on-a-chip solution Ethernet 802.11 a/g/b based embedded systems. Designed communication's routers, integrates bridge solution interfacing with 32-bit PCI, miniPCI, cardbus devices. KS8695P combines proven third generation 5-port managed switch, ARM9 RISC processor with MMU, five physical layer transceivers (PHYs) including their corresponding units with Micrel's XceleRouter technology. KS8695P built around 16/32-bit ARM9 RISC processor, which scalable, high-performance, microprocessor developed highly integrated system-on-a-chip applications. also offers configurable I-cache D-cache that reduces memory access latency high-performance applications. simple, elegant, fully static design KS8695P especially suitable cost-effective, power-sensitive applications. KS8695P contains five 10/100 PHYs: four local area network (LAN) wide area network (WAN). Connected PHYs five corresponding units with integrated Layer managed switch. combining switch analog PHYs make KS8695P extremely prudent solution SOHO router applications, saving both board space costs. Layer switch contains 16Kx32 SRAM on-chip memory frame buffering. embedded frame buffer memory designed with 1.4Gbps on-chip memory bus. This allows KS8695P perform full non-blocking frame switching and/or routing many applications media interface, KS8695P supports 10BASE-T 100BASE-TX, specified IEEE 802.3 standard, BASE-FX port port KS8695P supports modes operation environment: host bridge mode guest bridge mode. host bridge mode, ARM9 processor acts host entire system. configures other devices coordinates their transactions, including initiating transactions between devices subsystem. on-chip arbiter included determine ownership among master devices. host bridge mode, registers, including those embedded switch, configured ARM9 processor through on-chip AMBA interface. guest bridge mode, registers programmed either external host local ARM9 host processor through AMBA bus. KS8695P functions slave with on-chip arbiter disabled. KS8695PX configured either ARM9 host CPU. both cases, KS8695P memory subsystem accessible from either host ARM9 CPU. Communications between external host ARM9 accomplished through message passing through shared memory.
