草榴社区 Synchronous Serial Interface (SSI)
The 草榴社区 Synchronous Serial Interface IP addresses the demand for high transfer rates and low latency in serial flash memories for mobile, consumer, IoT, and automotive applications. SPI is a standard for serial NOR, NAND flash and PSRAMs as well as sensors and general-purpose connectivity. The IP supports the following standards:
- Motorola SPI Standard/Dual/Quad/Octal /Dual Octal
- JEDEC xSPI (JESD251B) v1.0
- Micron XccelaBus
- Infineon Technologies HYPERBUS? memory (Revision E)
- Texas instruments Synchronous serial protocol (SSP)
- National Semiconductor Microwire
Support for such standards allows the single IP instance to interact with multiple connected devices, supporting different protocols. Advanced features such as Execute in Place (XIP), Target Bridge mode, SPI Target Decoding, and Internal DMA allows easy access to the serial device and improves overall design performance. The standards-based Arm? AMBA? Advanced High-Performance Bus (AHB) or Advanced Peripheral Bus (APB) connects the IP to the rest of the SoC while the bus is connected to the register interface and the Direct Memory Access (DMA) interface, offering easy IP integration.
