中国电科14所解决国产雷达无“芯”之痛(图)
2017-07-07 13:09:43 中国电科十四所官方微信号
“华睿1号”是中国电科14所牵头研制的国内首款具有国际先进水平的高端四核DSP芯片,填补了我国多核DSP领域的空白。经过七年艰苦卓绝的奋斗,芯片设计、软件开发、平台研制、应用验证等工作顺利完成,目前华睿1号信号处理平台已成功应用于十多型雷达产品中,为我国雷达装备高端处理芯片国产化写下浓墨重彩的一笔。往昔历历在目,今朝点点于心。
筚路蓝缕,开拓创新,华睿1号芯动出岫
相信“华睿1号”项目团队的所有成员仍会清晰记得2010年12月27日北京人民大会堂北京厅里那场振奋人心的“核高基”重大专项---“华睿1号”DSP芯片发布会。那一天,我所正式对外宣布“华睿1号”这颗备受集成电路业界瞩目、填补国内多核DSP领域空白的芯片诞生了。
北京发布会现场
“产学研用”是“华睿1号”DSP项目的宗旨,芯片流片成功只是万里长征的第一步,接下来必须构建测试验证平台、应用验证平台,全面测试芯片的电性能参数、环境应力指标。北京发布会之后,一支高水平信号处理平台研制队伍应运而生,在没有技术积累和参照的条件下,他们从零起步、凭借着对国防事业的满腔热情和对事业的执着追求,相继攻克仿真、叠层、走线、工艺等关键技术,历经上百次仿真与迭代,最终突破了高速信号完整性、电源完整性、稳定性等技术难题。经过连续半年无休止的奋斗,华睿1号处理平台通过300小时应力试验,奠定了坚实的硬件基础。
2012年,“华睿1号”核高基课题验收会在北京举行,验收专家组对课题成果给予了高度评价和一致认可,成为“十一五”国家“核高基”高端芯片重大专项中首个通过验收的DSP项目。
栉风沐雨,软硬兼修,全国产化软件生态链脱颖而出
再高端的芯片,能否大规模应用,完备的软件生态链起决定性的作用。华睿1号课题验收并不是结束,而是新的开始。为解决vxWorks下GMAC网络驱动联合单位无法交付的困境,我所软件开发团队充分发挥党员模范作用,受芯片总师重托,迎难而上,扛起驱动研发任务,经过十五天不分昼夜的拼搏协作,终于在第二周周六下午3点联试成功,啃下了这块硬骨头;2014年,某外方软件合作单位咬文嚼字,借合同字面描述执意采用简单的矢量化方案,而该方案根本达不到原定的降低编程难度、简化开发过程的目标,我方据理力争、以一敌六、舌战群儒,成功说服外方按自动矢量化的方案实施。如此种种,不胜枚举。
