You can use CYUSB3014-BZXC for commercial or CYUSB3014-BZXI for industrial temperature range which uses 32-bit GPIF bus for data and 512 kB of SRAM for code and data. This data bus can be configured to 16 and also 8 bits based on your requirements.
Since you are using an image sensor with 8 or 10 bit parallel data, you can also use CYUSB3013 which has 16 bit GPIF bus or CYUSB3012 which has 32-bit but 256 kB of SRAM, based on the application requirements.
Please refer to the ordering information section in the FX3 datasheet.
All the parts mentioned in the datasheet has SPI interface which is needed for controlling the image sensor mentioned.
