摘要

研究了在多数据路径数字信号处理器上递归计算的实现。还提出了一种块浮点实现。这种实现只需要累加器中的一个保护位，从而降低了硬件的复杂性。与短字浮点或定点相比，这种实现具有更高的信号处理精度。

Block-floating-point implementation of recursive computations on a multiple datapath DSP

The realization of recursive computation on multiple datapath digital signal processors (DSPs) is studied. A block-floating-point implementation is also proposed. This implementation requires only one guard bit in the accumulator, thus leading to a low complex hardware. This implementation allows a superior signal processing accuracy compared to that of short-word floating-point or fixed-point.
