自1971年第一个微处理器由美国Intel公司研制成功以来,在短短的几年中已经有了30余种类型的微处理器。而且应用范围很广,从家用消费性电器直到工农业生产和军事部门。在数字信号处理领域中,也越来越多地利用微处理器。微处理器用于数字信号处理的优点是可以使功能软件化或固件化,大大地提高了处理系 Since the first microprocessor was successfully developed by Intel Corporation in the United States in 1971, more than 30 types of microprocessors have been available in just a few years. And a wide range of applications, from household consumer appliances until the industrial and agricultural production and the military sector. In the field of digital signal processing, more and more use of microprocessors. The advantage of microprocessors for digital signal processing is that the functions can be software or firmware, greatly improving the processing system
