Description: 在数字信号处理领域用的较多的是DSP和FPGA。DSP的优势源于多数信号处理算法的乘-累加运算都是非常密集的。FPGA通过多极流水线架构也能够用来实现MAC单元，并且FPGA技术可以通过一个芯片上的多级MAC单元来提供更多的带宽，速度可以比数字信号处理芯片快，并且功耗较低。CORD IC算法完全由移位和加法操作完成，因此利用FPGA可以实现更高的运算速度。采用流水线结构在FPGA上实现基于CORD IC的对数变换，可以达到80MHz的处理速度。

Description: 现场可编程门阵列（FPGA）已经不再单纯应用在芯片与系统之间的直接互联层，在软件无线电（SDR）中，FPGA逐渐用做通用运算架构来实现硬件加速单元，在降低成本和功耗的基础上提升性能表现。SDR调制解调器的典型实现包括通用处理器（GPP）、数字信号处理器（DSP）和FPGA。而且，FPGA架构可以结合专用硬件加速单元，用来卸载GPP或DSP。软核微处理器可以结合定制逻辑，扩展其内核，也可以将分立的硬件加速协处理器添加到系统中。此外，还可将通用布线资源放在FPGA中，这些硬件加速单元可以并行运行，进一步增强系统的整体运算输出能力-Field programmable gate array (FPGA) is no longer a simple chip and system used in the direct interconnection between the layers, in the Software Defined Radio (SDR) in, FPGA increasingly used as general-purpose computing architecture to achieve hardware acceleration units to reduce costs in and power consumption based on the performance upgrade. SDR modem to achieve a typical general-purpose processor, including (GPP), digital signal processor (DSP) and FPGA. Moreover, FPGA architecture can be combined with dedicated hardware acceleration units to uninstall GPP or DSP. Soft-core microprocessors can combine custom logic and to expand its core, it can be the separation of hardware-accelerated co-processor added to the system. In addition, resources can also be placed on general-purpose FPGA routing, these hardware acceleration units can be run in parallel, to further enhance the overall computing system, the output capacity
