●UltraScale+ MPSoCs are built around a feature-rich quad-core ARM Cortex-A53 and dual-core ARM Cortex-R5 processing system (PS). In addition to the 32-bit/64-bit application processing unit (APU) and 32-bit real-time processing unit (RPU), the PS contains a dedicated ARM Mali™-400 MP2 graphics processing unit (GPU). To support the processors" functionality, a number of peripherals with dedicated functions are included in the PS. For interfacing to external memories for data or configuration storage, the PS includes a multi-protocol dynamic memory controller, a DMA controller, a NAND controller, an SD/eMMC controller and a Quad SPI controller. In addition to interfacing to external memories, the processing units also contain their level 1 and/or level 2 caches and 256KB of on-chip memory. For high-speed interfacing, the PS includes 4 channels of transmit (TX) and receive (RX) pairs of transceivers, called PS-GTR transceivers, supporting data rates of up to 6.0Gb/s. These transceivers can interface to the high-speed peripheral blocks to support PCIe Gen2 root complex or end point in x1, x2, or x4 configurations; Serial-ATA (SATA) at 1.5Gb/s, 3.0Gb/s, or 6.0Gb/s data rates; and up to two lanes of Display Port at 1.62Gb/s, 2.7Gb/s, or 5.4Gb/s data rates. The PS-GTR transceivers can also interface to components over USB 3.0 and Serial Gigabit Media Independent Interface (SGMII). For general connectivity, the PS includes: a pair of USB 2.0 controllers, which can be configured as host, device, or On-The-Go (OTG); an I2C controller; a UART; and a CAN2.0B controller that conforms to ISO11898-1. There are also four triple speed Ethernet MACs and 128 bits of GPIO, of which 78 bits are available through the MIO and 96 through the EMIO. High-bandwidth connectivity based on the ARM AMBA® AXI4 protocol connects the processing units with the peripherals and provides interface between the PS and the programmable logic (PL).
