Table 1: OX16PCI950 performance compared with PLX + generic UART combinations
Note 1:
Improvements of the OX16PCI954 over discrete solutions:
Zero wait-state applies only to internal UARTs
Higher degree of integration:
OX16PCI954 offers four internal 16C950 high-performance
UARTs and one bi-directional parallel port.
Improved access timing:
Access to 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:
OX16PCI954 offers shadowed FIFO levels and Interrupt
status registers of internal UARTs, and Interrupt Status of
internal UARTs and MIO pins to reduce the device driver
interrupt latency.
