5.2 Frame Store Controller
The Frame Store Controller (FSC) coordinates pixel data transfer between the FS400 and the Frame
buffer. For normal operation, a 16 Mbit SDRAM is connected to the frame store controller port.
Supported SDRAM parts include:
The refresh of data in the SDRAM is accomplished through the continual update of the video output
display. Therefore, any SDRAM selected must meet the frame rate maximum delay of the selected
video. The worst case delay time is for PAL systems (25 frames/s) requiring a retention time of 40ms or
greater.
Data from the Capture Engine is written into the frame store in parallel with the extraction of data for the
encoder engine. Read and write buffers at the data port allow data to be transferred in bursts without
interruption of the overall flow of pixels. Bandwidth of the FSC bus is 80 MHz or 100 MHz, sufficient to
support maximum rate write cycles from the Capture Engine simultaneously with full rate Encoder Engine
read cycles.
