7.3.3 System Control

Overview

System control is used to initialize and deinitialize the entire media system, and establish relationships between modules through binding interfaces. It provides the VP (Video Pool) module for managing large blocks of physical memory allocation.

Functional Description

Video Pool

The VP (Video Pool) video pool provides large blocks of physical memory and management functions, and is responsible for memory allocation and recovery. The video pool is composed of a group of physically contiguous and equally sized buffer blocks. It needs to be configured and initialized before use. The number of buffer pools and the size of buffer blocks can be configured according to the needs.

Binding Relationship

Note: The binding relationship between modules can be established using the HB_SYS_Bind interface. Once bound, the data processed by the data source will be automatically sent to the data sink.

Operation Mode

Online Mode: The data between modules is directly transferred from the previous module to the next module through the internal bus without the need to read/write DDR. This can reduce latency and save DDR bandwidth.

Offline Mode: The data from the previous module is first written to DDR, and then the next module reads the data from DDR. When multiple sensors are connected, all connected sensors are processed offline.

Mode	VIN_SIF and VIN_ISP	VIN_ISP and VPS	VIN_SIF and VPS
Online	SIF(RAW) --> ISP	ISP(YUV) --> VPS	SIF(YUV) --> VPS
Offline	SIF(RAW) --> DDR --> ISP	ISP(YUV) --> DDR --> VPS	SIF(YUV) --> DDR --> ISP

Note: The HB_SYS_SetVINVPSMode interface is used to set the operation mode between VIN and VPS.
