mapped SRAM low-latency access. Used 256KB SRAM 4-way set-associative, unified data/instruction cache, which benefit many applications. memory-mapped SRAM, lower memory access latency than SDRAM, offering quick access crucial code data. Softwarecontrolled with parity support, this memory ideal storing data packets, critical code segments, Ethernet descriptors, other application-specific data. When configured memory-mapped region, this SRAM accessible from master, which further improve application performance.
Gigabit Ethernet TCP/IP assist extend application capability 440GX integrates four Ethernet media access controllers (MACs), including 10/100Mb interfaces 10/100/1Gb interfaces with support jumbo packets TCP/IP assist. These MACs offer both flexibility high performance. example, they configured provide four SMII interfaces maximum connectivity; dual gigabit interfaces high-speed communications, plus Fast Ethernet interfaces other application requirements. Many networking storage applications will benefit from PowerPC 440GX software-enabled TCP/IP hardware-assist state machine that accelerates data packet
bits, depending transaction. Conformance these architectures facilitates helps reduce cost application development migration. PowerPC tools support fast time-to-market PowerPC embedded processors supported more than third-party vendors through PowerPC Embedded Tools Program. This program provides compilers, debuggers, real-time operating systems, emulators, logic analyzers, full range tools help manufacturers develop products quickly efficiently.
