Fast Simplex Link (FSL) is a 32-bit wide interface on MicroBlaze. The FSL channels are uni-directional, point-to-point data streaming interfaces.[1] A MicroBlaze processor supports up to eight FSL channels.[2] This interface allows MicroBlaze processors to communicate with peripherals or other processors.[3] The FSL can be used for extending the processor execution unit with custom hardware accelerators thanks to a low latency dedicated interface to the processor pipeline. In addition, the same FSL channel can be used to transmit or receive either control or data words. The interface is FIFO, and a separate bit indicates whether the transmitted, or received, word is control or data information.[4] FSL has low latency compared to CoreConnect's On-chip Peripheral Bus.[5]
