12v pure sine wave inverter 1000w

SP chip, also known as digital signal processor, is a kind of microprocessor which is especially suitable for digital signal processing operations. Its main application is to realize various digital signal processing algorithms in real time and quickly. According to the requirements of digital signal processing, DSP chips generally have the following main characteristics:

　　 (1) One multiplication and one addition can be completed in one instruction cycle;

　　 (2) The program and data space are separated, and instructions and data can be accessed at the same time;

　　(3) There is fast RAM on the chip, which can usually be accessed in two blocks simultaneously through an independent data bus;

　　 (4) Hardware support with low overhead or no overhead loop and jump;

　　 (5) Fast interrupt processing and hardware I/O support;

　　 (6) Multiple hardware address generators that operate in a single cycle;

　　(7) Multiple operations can be executed in parallel;

　　(8) Support pipeline operation, so that operations such as fetching, decoding and execution can be performed overlappingly.

　　 Of course, compared with general-purpose microprocessors, other general-purpose functions of DSP chips are relatively weak.
