In order to make application development get rid of bottom hardware restriction, and to invoke hardware device through a general interface, device interface is defined in SCA system.
为了使应用的开发摆脱底层硬件的制约,使应用能通过一个统一的接口调用硬件设备,在SCA系统里定义了设备接口。
The device interface defined in SCA system can shield the details of hardware function implementation and release the toplevel waveform application development from bottom hardware restriction.
SCA系统里定义的设备接口能屏蔽硬件功能实现的细节,使上层波形应用的开发摆脱底层硬件特性的制约。
Hardware can be kept behind locked doors, but often employees find this restriction a hindrance, so security is lax.
硬件可以锁起来,但雇员常常觉得这种约束很麻烦,因此安全措施也就松弛了。
