UART 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.
