Dual Port Memory
The basic throughput problem faced by digitizers is that almost all of them use
single-port memory, i.e. if you are reading data from the acquisition memory,
you cannot capture into it and vice-versa.
This requires a software handshake which is heavily dependent on the operating
system response time.
ATS9353 solves this problem by providing on-board memory that can act as a
very deep FIFO and an advanced custom DMA engine that can stream data to PC
host memory at up to 1.6 GB/s (exact rate is motherboard dependent).
The bottom line is that software does not have to wait until the end of data
capture to read the acquired data.
