MicroBlaze Soft Processor Core

Local Memory Bus

Local Memory Bus (LMB) areĀ used for connecting to local block RAM (faster), instruction, and data (user selectable). It is and internat bus dedicated for connection between the MicroBlaze Core and memory functions.

Fast Simplex Links

Fast Simplex Links (FSL) is a dedicated, unidirectional point-to-point data streaming interfaces; support for up to 16 FSLs. Often used for connection between dedicated functionality that needs to be off-loaded to FPGA slice resources. This could e.g. be large multipliers that runs faster on dedicated hardware than in the MicroBlaze Core.

Dedicated CacheLink

Dedicated CacheLink ports for instruction and data caching with four-word cache line size and critical word-first access capability.
