The Synopsys USB 1.1 Controllers support Full and Low Speed based on USB specification from the USB Implementer Forum. The Synopsys USB 1.1 IP offering consists of the USB 1.1 Device and USB 1.1 OHCI Host controllers for integration into SoCs, and Verilog testbench for integration testing. These elements enable quick development of SoC designs incorporating the USB 1.1. The Synopsys USB 1.1 IP is targeted for SoCs requiring the smallest area and lowest power, such as those used in IoT applications.
The DMA in the Device controller and list processor in the Host controller reduce interrupts to the CPU/MPU and bus, reducing power consumption and leaving MIPS and bus bandwidth for other functions.
