Table 1: OX16PCI952 performance compared with PCI Bridge + generic UART/Parallel Port Combinations.
1.1
Improvements of the OX16PCI952 over discrete solutions:
Higher degree of integration:
The
OX16PCI952
performance 16C950 UARTs and one IEEE1284 compliant
bi-directional parallel port.
UART device driver efficiency is increased by using each
channel’s features such as the 128-byte deep transmtter &
receiver FIFOs, flexible clock options, automatic flow
control, programmable interrupt and flow control trigger
levels and readable FIFO levels. Data rates of each UART
is up to 60Mbps.
offers
two
internal
ultra-high
Improved access timing:
Access to the internal UARTs require zero or one PCI wait
states. A PCI read transaction froman internal UART can
complete within five PCI clock cycles and a write
transaction to an internal UART can complete within four
PCI clock cycles.
Reduces interrupt latency:
The OX16PCI952 offers shadowed FIFO levels and
Interruptstatus registers of the internal UARTs, as well as
general device interrupt status, to reduce the device driver
interrupt latency.
