n= number of bits per sample in the regular DSP system using the minimum sampling rate From Equation (12.20) and given the number of bits (m) used in the oversampling scheme, we can determine the number of bits per sample equivalent to the regular ADC. On the other hand, given the nu...
A novel quantization error (QE) compensation method is proposed in design of high accuracy fixed-width radix-4 Booth multipliers, which will effectively reduce the QE and save the area of multipliers when they are employed in cognitive radio (CR) detector and digital signal processor (DSP). ...

Based on Figure 11.1, the recovered voltage and quantization error are found to be xq=0andeq=0−0.5=−0.5volts As discussed in Chapter 2, the linear midtread quantizer introduces quantization noise, as shown in Figure 11.1; the signal-to-noise power ratio (SNR) is given by (11.1)SNR=...
量化(quantized),即将神经网络前向过程中浮点数运算量化为整数运算,以达到计算加速的目的。通常是指将float32转化为int8进行运算,经实践部署dsp上能提升2.5~3倍左右的推理速度。我们知道对浮点数的量化操作是将其从一个高维度映射到低维度的转换过程,如图所示: ...
自动化所的一篇文章, 文章地址, 代码地址 文章主要有两个创新点 将量化后的weigths进行split, 然后优化每一位bit, 使得目标函数最小, 得到每一位的bit后再将所有位的bit进行stitching 在保证计算效率的前提下, 可以对Activation使用per-channel的量化, 论文中叫Error Compensated Activation Quantization(ECA...【...

In this case the encoder is in danger of generating too many bits for the channel to transfer to the decoder, thereby causing a "VBV underflow" bit stream error. In this case, the encoder enters the panic mode in which quality is sacrificed to guarantee a legal bit stream. (8) The ...
In another embodiment, such as when system 50 implements an adaptive IIR filter, program memory 55 would preferably include the coefficient calculation routine to periodically adapt the coefficients. DSP 60 is a general-purpose digital signal processor which has a high degree of internal parallelism...
