system crash which could cause no ACK frame
received. After retransmitting for several times,
TSoverHTCP will send CPU an interrupt to clear
the current connnection state.
6 TEST AND RESULT
To evaluate TSoverHTCP, it was implemented on
an FPGA using Stratix IV as an FPGA test board.
Table 1 shows the resource utilization of TSover-
HTCP. TSI_FIFO block uses a 4 K-bit inner
RAM to buffer input TS packets and TX_BLOCK
and RX_BLOCK use a 16 K-bit inner RAM to
buffer frames sent and received. TX_BLOCK and
ACK_PARSER cost a lot of resources because
TCP control logic.
The entire TSoverHTCP test environment is
shown in Figure 8. A CPU (LH79520), a ...
