. 4.2.5 MAP PCB circuit description
4.2.5.1 General Description
MAP PCB is divided into the following 6 blocks.
These 6 Blocks are processed by four MAPs (Media Accelerated Processor) carried in two MAP
PCBs.

EPI PCB
Q
1. TCI I/F
This block extracts monochrome data, Doppler data and CFM data from the TCI (Transport
Channel Interfaces) data from EPI PCB.
2. BW Echo Processing
This block calculates monochrome scalar data from complex data.
3. Doppler Calculation
This block calculates pulse wave Doppler data or continuous wave Doppler data from
complex data.
4. Color Doppler Calculation
This block calculates CFM data from complex data.
