3.2.5.4
Display module
Processing of graphic and image integration and provision of control interface for main
CPU to graphic memory
The graphic memory is directly accessed by CPU.
Interface control of video input and output
3.2.5.5
CPU system
The CPU system is the control core of the ultrasound system, consisting of hardware
system and software system. The hardware provides support for functions of the system
software, and the software realizes the control of hardware modules. The functions of the
CPU system include: image display and measurements, and human-machine interaction.
Communicating with other MCU or DSP, and configuring, initializing, and monitoring each
hardware module;
Initialization configuration for system FPGA and DSP;
System control: parameter control for FPGA; management for system controllers; on-line
upgrading of each MCU.
