MCF5249LPV120：集成式ColdFire V2微處理器

MCF5249LPV120 微處理器為常用的V2 ColdFire內(nèi)核實(shí)現(xiàn)了新的性能水平，在頻率為120MHz的情況下其性能超過(guò)了125 (Dhrystone 2.1) MIPS；為ColdFire器件實(shí)現(xiàn)了最低的功耗（1.3mW/MHz）。這款高集成度的微處理器采用了廣泛使用的ColdFire外設(shè)組合，并添加了新的音頻增強(qiáng)和模擬功能以及增強(qiáng)型乘法累加單元（eMAC）、大型片上存儲(chǔ)器（96K SRAM、8K I-緩存）和SDRAM控制器。MCF5249LPV120 器件是下列應(yīng)用的理想之選：需要為文件管理、數(shù)據(jù)緩沖和用戶(hù)界面進(jìn)行大量控制處理的應(yīng)用，以及各種主要市場(chǎng)（如安全、游戲、醫(yī)療和數(shù)字音頻）上需要進(jìn)行信號(hào)處理的應(yīng)用。高集成度、高性能和低功耗組合可以通過(guò)利用高質(zhì)量軟件模塊、輕松的代碼重用和廣泛的第三方工具支持實(shí)現(xiàn)快速的面市。

The MCF5249LPV120 microprocessor delivers a new level of performance on the popular Version 2 ColdFire core with over 125 (Dhrystone 2.1) MIPS @ 120MHz and the lowest ever power consumption (1.3mW/MHz) on a ColdFire device. This highly integrated microprocessor builds upon the widely used ColdFire peripheral mix by adding new audio enhancements and analog functionality, in addition to an enhanced Multiply Accumulate Unit (eMAC), large on-chip memory (96K SRAM, 8K I-Cache), and a SDRAM controller. The device is ideal for applications requiring significant control processing for file management, data buffering, and user interface, as well as signal processing in a variety of key markets such as security, gaming, medical, and digital audio. This leading package of integration, high performance, and low power consumption allows fast time to market through access to high quality software modules, easy code reuse, and extensive third party tool support.
