MC7447AHX1420LB数据手册恩XP中文资料规格书

描述 Description

The MPC7447A processor is a high-performance, low-power, 32-bit implementation of the RISC architecture. Key architectural features include 512 KB of on-chip L2 cache, a 64-bit bus interface and a full 128-bit implementation of Our AltiVec®™ technology. MPC7447A processors are ideal for leading-edge computing, embedded network control and signal processing applications.
Designed as pin-compatible replacements for Our MPC7447 products, these new processors have been shown to reach speeds of 1.5 GHz. MPC7447A processors benefit from Our silicon-on-insulator (SOI) process technology, engineered to help deliver significant power savings without sacrificing speed. Low-power versions of the MPC7447A are available.
Embedded EnhancementsThe MPC7447A offers eight instruction BAT and data BAT registers to help support lightweight embedded operating systems, enabling more large tables of data. The processors also provide cache locking to the L1 caches so that key performance algorithms and code can be locked in the L1 cache.  

特性 Features

Superscalar Microprocessor MPC7447A processors feature a high-frequency superscalar core based on PowerArchitecture technology, capable of issuing four instructions per clock cycle(three instructions plus one branch) into 11 independent execution units:
• Four integer units (three simple plus one complex)
• Double-precision floating point unit
• Four AltiVec® technology units (simple, complex, floating and permute)
• Load/store unit
• Branch processing unit
New Power Management Features
• Clock frequency can be changed dynamically
• Temperature sensing diodes included to monitor die temperature
Compatability and Support
• MPC7447A processors are pin for pin compatible with MPC7445 and MPC7447processors.
• As with all microprocessors built on Power Architecture technology, MPC7447Aprocessors are software compatible with the MPC7xx family of processors fromNXP®.
• Microprocessors built on Power Architecture technology enjoy a broad setof operating systems, compilers and development tools from third-party vendors.
