技术文摘：IMES解密史上功耗最低的ADRES多措置器架构！

IMEC claims, its Coarse-grained(coarse grain) VLIW multiprocessing implement framework ADRES (Architecture For Dynamically Reconfigurable Embedded Systems, trends can match built-in framework again) the foundation that is regarded as video decipher to be able to configure processor research and development again, the processor of C process designing that the power that saves compares popularity is as high as 6 to arrive 12 times. ADRES has an operation same kind C is compiled implement, the ability of freely is allocated between the one dimension array that dictates at train in excess specified length in the job matrix type leaves functional unit and the 2 dimension array that handle an element. This one trends is comfortable matching capacity is those who make functional unit poses problem of power comsumption of static VLIW equipment " No-ops " appear the smallest occurrence by way of. This processor supports MPEG-2, MPEG-4 and H.264/AVC video decipher, resolution comes high from QVGA D1. Through FPGA implementation is in CIF resolution with 30 frame / decipher of second H.264/AVC video revealed its function. For video of resolution of CIF of real time decipher, the total capacity of the ADRES processor of this multimedia (50MHz) was used only 1/6, power comsumption is emulated to be 17mW about when ASIC comes true. IMEC expresses, obtain high energy efficiency to show ADRES reachs his to compile implement agree with compositive arrive inside device of portable wireless multimedia. A of IMEC curule express further, IMEC will offer this kind of processor possibly to industrial group. "Had this to demonstrate implement, we obtained very important milestone in project of much mode multimedia. It makes clear, ADRES framework pattern plate and compile correspondingly implement enough to supporting industrial product research and development to transfer stability and can operate. " the vice-president Rudy Lauwereinsbiaoshi that IMEC is in charge of designing science and technology expresses. ADRES is the much mode multimedia in IMEC (M4) industry combines the research and development below project name. SamSung electron and the member that fly to company of semiconductor of the Er that think of card to all be M4 project, barco Silex designs the job to be contributed somewhat to multimedia processor.

IMEC宣称，其coarse-grained(毛糙纹理型)VLIW多措置器架构ADRES (Architecture for Dynamically Reconfigurable Embedded Systems，动静可重配嵌入架构)被作为视频解码可重设置装备摆设措置器研发的根本，所节省的功率比风行的C编程措置器高达6到12倍。

ADRES具备操作统一种C编译器，在工作于超长指令字模式下性能单元的一维阵列和措置元素的二维阵列之间调配自如的能力。这一动静适配能力是使性能单元引起静态VLIW行动措施功耗问题的“no-ops”呈现最小化的路过。

该措置器撑持MPEG-2、MPEG-4 和 H.264/AVC视频解码，分辨率从QVGA高至D1。经由过程FPGA实此刻CIF分辨率以30帧/秒 H.264/AVC 视频解码展示了其性能。为了实时解码CIF分辨率视频，这款多媒体的ADRES措置器的总容量(50MHz)只用了六分之一，ASIC实现时仿真功耗约为17mW。

IMEC暗示，获得高能量效率剖明ADRES及其编译器适合于集成到便携式无线多媒体安装内。IMEC的一位高官进一步暗示，IMEC可能将向工业界供给这种措置器。

“有了这款演示器，咱们在多模式多媒体项目中获得了很是主要的里程碑。它剖明，ADRES架构模板及对应的编译器对于撑持工业产物研发转移足够不乱和可操作。”IMEC负责设计科技的副总裁Rudy Lauwereinsbiaoshi暗示。

ADRES是在IMEC的多模式多媒体 (M4)工业连系项目名义下研发的。三星电子和飞思卡尔半导体公司均为M4项目标会员， Barco Silex对多媒体措置器设计工作有所进献。
