4.2.4
IQDAS (IP)
<introduction>
IP PWB is included in UIIP-770A
Part No.
: PM30-32120-1
Part Name
: IQDAS PWB (IQDAS stands for IQ Data Acquisition)
Requirements
: Aplio on & after V4.00
<Circuit blocks>
1) Data-IF section (between BE PWB)
2) Capture memory section
3) Temporary storage memory section
4) DMA Controller section
5) PCI-IF section
<Outline of circuit functions>
This board takes IQ (In Phase, Quadrature
Phase) data or IM (Image Memory) data output from
BE PWB SIP section into capture memory with real time by memory R/W control FPGA.
It is possible to store the particular part of taken data into the temporary
storage memory.
Because of this temporary storage memory, it is possible to continue capturing data without
stopping examination
finished, several captured data in the temporary storage memory is
transferred to the system memory by DMA via PCI bus.
