EP7312-IR-90規(guī)格書詳情

EP7312-IR-90屬于集成電路(IC)的微處理器。由凌云邏輯制造生產(chǎn)的EP7312-IR-90微處理器微處理器產(chǎn)品是用于信息和數(shù)據(jù)處理的集成電路。與主要按照制造商所選術(shù)語而視為微控制器的類似產(chǎn)品相比,這些器件有所不同。但是按照傳統(tǒng),微處理器不會(huì)在設(shè)備內(nèi)集成工作存儲(chǔ)器,不太可能集成混合信號(hào)外設(shè),并且可能在更為復(fù)雜的軟件范式下使用,這些范式涉及使用操作系統(tǒng)來管理多任務(wù)同時(shí)執(zhí)行。

OVERVIEW

The Cirrus Logic? EP7312 is designed for ultra-low-power portable and line-powered applications such as portable consumer entertainment devices, home and car audio juke box systems, and general purpose industrial control applications, or any device that features the added capability of digital audio compression & decompression. The core-logic functionality of the device is built around an ARM720T processor with 8 kBytes of four-way set-associative unified cache and a write buffer. Incorporated into the ARM720T is an enhanced memory management unit (MMU) which allows for support of sophisticated operating systems like Microsoft? Windows? CE and Linux?.
