SP的性能受其对存储器子系统的管理能力的影响。如前所述，MAC和其它一些信号处理功能是DSP器件信号处理的基本能力，快速MAC执行能力要求在每个指令周期从存储器读取一个指令字和两个数据字。有多种方法实现这种读取。比如，使用多接口存储器（允许在每个指令周期内对存储器多次访问）、分离指令和数据存储器（“哈佛”结构及其派生类）以及指令缓存（允许从缓存读取指令而不是存储器，从而将存储器空闲出来用作数据读取）另外要注意所支持的存储器空间的大小。许多定点DSP的主要目标市场是嵌入式应用系统，在这种应用中存储器一般较小，所以这种DSP器件具有小到中等片上存储器（4K到64K字左右），备有窄的外部数据总线。另外，绝大多数定点DSP的地址总线小于或等于16位，因而可外接的存储器空间受到限制一些浮点DSP的片上存储器很小，甚至没有，但外部数据总线宽。例如TI公司的TMS320C30只有6K片上存储器，外部总线为24位，13位外部地址总线。而ADI的ADSP2-21060具有4Mb的片上存储器，可以多种方式划分为程序存储器和数据存储器。选择DSP时，需要根据具体应用对存储空间大小以及对外部总线的要求来选择。

Working humidity: Maximum relative humidity of 95% (non condensing).

Pollution level (IEC 60721-3-3): Chemical gas 3C3 level, solid particle 3S3 level

The performance of an SP is influenced by its ability to manage storage subsystems. As mentioned earlier, MAC and other signal processing functions are the basic capabilities of DSP device signal processing, and the fast MAC execution capability requires reading one instruction word and two data words from memory in each instruction cycle. There are multiple ways to achieve this reading. For example, using multi interface memory (allowing multiple access to memory within each instruction cycle), separating instruction and data memory (Harvard structure and its derived classes), and instruction caching (allowing instructions to be read from the cache instead of memory, thus freeing up memory for data reading), also pay attention to the size of supported memory space. The main target market for many fixed-point DSPs is embedded application systems, where the memory is generally small, so this type of DSP device has small to medium on-chip memory (around 4K to 64K words) and is equipped with a narrow external data bus. In addition, the address bus of the vast majority of fixed-point DSPs is less than or equal to 16 bits, resulting in limited external memory space. Some floating-point DSPs have very small or even no on-chip memory, but their external data bus is wide. For example, TI's TMS320C30 only has 6K on-chip memory, and the external bus is a 24 bit and 13 bit external address bus. The ADSP2-21060 of ADI has a 4Mb on-chip memory, which can be divided into program memory and data memory in various ways. When selecting a DSP, it is necessary to choose based on the specific application's storage space size and external bus requirements.
