【摘要】 随着数字信号处理技术的发展,开发应用高速DSP处理器芯片进一步提高运算处理速度是主要的发展方向。介绍了用DSP56001数字信号处理器芯片以及位反转算法实现24位定点字长1024点基2DITFFT的技术细节,经实测可在5.6ms内完成,这一处理速度在同类DSP处理器中是令人瞩目的。更多还原

【Abstract】 As the digital signal processors are developed, the processing rate of DSP application becomes more and more important. This paper describes the details of DSP56001’s addressing modes and it’s modifiers, which allow the DSP address ALU to support 3 types of arithmetic, that are linear arithmetic, modulo arithmetic, especially bit-reversed arithmetic used for performing 1024 Points FFT can finish processing procedure within 5.6ms.更多还原
