做DSP最应该懂得157个问题（回答） 四.5V/3.3V如何混接？ TI DSP的发展同集成电路的发展一样，新的DSP都是3.3V的，但目前还有许多外围电路是5V的，因此在DSP系统中，经常有5V和3.3V的DSP混接问题。在这些系统中，应注意： 1)DSP输出给5V的电路（如D/A），无需加任何缓冲电路，可以直接连接。 2)DSP输入5V的信号（如A/D），由于输入信号的电压>4V，超过了DSP的电源电压，DSP的外部信号没有保护电路，需要加缓冲，如74LVC245等，将5V信号变换成3.3V的信号。 3)仿真器的JTAG口的信号也必须为3.3V，否则有可能损坏DSP。 五.为什么要片内RAM大的DSP效率高？

With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

The TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-point, digital signal processor (DSP) families (hereafter referred to as the ’54x unless otherwise specified) are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. These processors also provide an arithmetic logic unit (ALU) that has a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. These DSP families also provide a highly specialized instruction set, which is the basis of the operational flexibility and speed of these DSPs.

A programmable digital signal processor (PDSP) is a special-purpose microprocessor with specialized architecture and instruction set for implementing DSP algorithms. Typical architectural features include multiple memory partitions (onchip, off-chip, data memory, program memory, etc.), multiple (generally pipelined) arithmetic and logic units (ALUs), nonuniform register sets, and extensive hardware numeric support [1,2]. Single-chip PDSPs have become increasingly popular for real-time DSP applications [3,4].
