CUART is
a configurable multi-channel Universal Asynchronous
Receiver Transmitter Core, designed to be compatible
with the Industry standard 16550 UART. CUART
supports a maximum of 32 channels simultaneously
and these channels can be individually configured
and operated. The hardware configurable options
allow core generation tailored to specific application
needs. It can be readily integrated in many
of the existing SOC environments.
The CUART provides modem control capability
for each individual channel. In addition, two
general-purpose output signals are provided
for external device configuration. GDA's CUART
is a cost-effective, end-to-end system validated
solution that allows the licensees to easily
migrate to FPGA, Gate array and Standard cell
technologies optimally.
