ADSP-2185中文资料16-bit, 33 MIPS, 5 v, 2 serial ports, host port, 80 KB RAM数据手册ADI规格书

描述 Description

The ADSP-2185 is a single-chip microcomputer optimized for digital signal processing (DSP) and other high speed numeric processing applications.

The ADSP-2185 combines the ADSP-2100 family base architecture (three computational units, data address generators and a program sequencer) with two serial ports, a 16-bit internal DMA port, a byte DMA port, a programmable timer, Flag I/O, extensive interrupt capabilities and on-chip program and data memory.

The ADSP-2185 integrates 80K bytes of on-chip memory configured as 16K words (24-bit) of program RAM and 16K words (16-bit) of data RAM. Power-down circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-2185 is available in 100-pin LQFP package.

In addition, the ADSP-2185 supports new instructions, which include bit manipulations- bit set, bit clear, bit toggle, bit test- new ALU constants, new multiplication instruction (x squared), biased rounding, result free ALU operations, I/O memory transfers and global interrupt masking, for increased flexibility.

简介

ADSP-2185属于集成电路（IC）的DSP（数字信号处理器）。由制造生产的ADSP-2185DSP（数字信号处理器）数字信号处理器是类似于微处理器或微控制器的器件，但区别在于其内部架构经修改，适用于对连续数据流连续执行以乘法和加法运算为主的算法，而不是以条件逻辑或大量并发进程为主的算法。该器件通常用于诸如音频或视频信号处理等应用。
