Brazil's new defense paradigm

In 2015, Brazil has taken steps toward re-consolidating its domestic defense industry. In the 1980s, Brazil built a dynamic and diversified defense industry. The state-driven effort resulted in a tripod strategy, where the state, state-run companies, and their private sector became the pillars of Brazil's defense industry. Brazil developed an export-driven defense industry; where close to 80–90% of its output was exported to Latin American, African, Arab, and Asian nations. In the 1980s, Brazil became the world's fifth largest exporter of defense products and services, exporting to over 40 countries. In the 1990s and 2000s, Brazil's defense industry suffered a dramatic reduction in size, diversification, and momentum. Successions of domestic political and economic policies have relegated Brazil's once emerging defense industry to a marginal position in the global defense industry. This article analyzes future prospects, challenges, and growth strategies for Brazil's defense industry.     

The contexts of strategy as a guide for defense planning in the Philippines

Efforts toward developing an independent and credible Philippine defense policy were revived when Benigno Simeon C. Aquino III was elected President of the Philippines in 2010. President Aquino renewed the military modernization program in 2012 and emphasized the necessity of a “minimum credible defense posture.” Given the modernization efforts of the government, this article aims to contribute to the development of the concept of minimum credible defense posture by exploring how theory contributes to defense planning. It argues that the contexts of strategy are useful in planning for national defense because these contexts can provide a conceptual framework for defense planners. It proceeds in three parts: the opening section reviews the literature on defense planning; the second surveys the context of developing strategies as discussed in the General Theory of Strategy; and the last provides a definition of minimum credible defense and applies the context of developing strategies to the case of the Philippines.     

多核数字信号处理器矩阵乘卷积算法性能评测

矩阵乘卷积算法能够为各种卷积配置提供高性能基础实现,是面向给定芯片进行卷积性能优化的首要选择。针对国防科技大学自主研制的飞腾异构多核数字信号处理器(digital signal processor, DSP)芯片的特征以及矩阵乘卷积算法自身的特点,提出了一种面向多核DSP架构的高性能并行矩阵乘卷积实现算法ftmEConv。该算法由输入特征图转换、卷积核转换、矩阵乘以及输出特征图转换这四个均运行在通用多核DSP上的并行化部分构成,通过有效挖掘通用DSP核中功能单元的潜力来提升各个部分的性能。实验结果表明,ftmEConv实现了高达42.90%的计算效率,与芯片上的其他矩阵乘卷积算法实现相比,获得了高达7.79倍的性能加速。
