在过去的几年里,数字信号处理(DSP)技术不断发展并逐步走向成熟.今天的DSPIC已具有较高的时钟速率和较低的电压和功率需求,因而普遍应用于蜂窝通信、图形以及多媒体等方面.Sharp Electronics公司的高性能DSP产品系列现又增加了一种新的型号LH9124L.这是一个可用于高速阵列处理和面向块应用的25MHz、24位定点DSP芯片.它可以实时处理8位到24位数据,并可在时域和频域内实现数字滤波、图像识别、压缩、频谱分析、相关、卷积以及自适应滤波等功能.
Digital signal processing (DSP) technology has evolved and matured in the past few years, and DSPICs today have high clock rates and low voltage and power requirements and are therefore commonly used in cellular communications, graphics, and multimedia Etc. A new model, the LH9124L, is now added to Sharp Electronics’ high-performance DSP product line, a 25MHz, 24-bit fixed-point DSP chip for high-speed array processing and block-oriented applications that handles real- To 24-bit data and features such as digital filtering, image recognition, compression, spectrum analysis, correlation, convolution, and adaptive filtering in the time and frequency domains.
