1. DSA-Interface Specification
The DSA bus is an asynchronous and bidirectional communication bus designed internally for communication between a group of two microprocessors.
It has three bidirectional lines:
● Data-start synchronization and Data Transmission
● STB-data Election (data is valid when STB Is low)
● Ack-start synchronization, data transmission, confirmation and communication response

Two operations: A and B:
1: copy the range [x, x + k-1] of array A to the range [y, Y + k-1] of array B.
2: Ask the current value of B [X.
Idea: You can use the line segment tree to maintain the following values in the online segment tree: STA and STB. These two values are meaningful only for the leaf nodes of the online segment tree. For a position Po, (that is, the line segment [Po, po], whic

When we query information in the database, we often need to query the information based on the conditions entered by the user. Some conditions are available, but some conditions are unavailable. Therefore, we need to assemble the condition statements. The following method is compiled based on this situation, hoping to help the reader:
String SQL = "select * from table where"; // the next space after where stringbuffer STB = new stringbuffer (SQL);
. So although the TS Stream format is in MEPG-2
Defined, but it can also be used to pass the media file of the MEPG-4, just because it is defined in the MPEG-2, so it is often called the MEPG-2 TS stream.
In terms of media processing methods, from the encoding end to the decoding end, we need to establish multiple RTP for audio and video and other data streams.
Session. Therefore, when I/O is used as a streaming media server, you need to manage multiple input and output, multiple buffer manageme
