Unsourced material may be challenged and removed. The MPU provides protection and caching strategies across the entire memory space. For some applications, the DSP features are central.
Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. What is regarded as the Blackfin “core” is contextually dependent. Other applications use the RISC features, which include memory protection, different operating modes user, kernelsingle-cycle opcodesdata and instruction caches, and instructions for bit test, byte, word, or integer accesses and a variety of on-chip peripherals.

This allows the processor to execute up to three instructions per clock cycle, depending on the level of optimization performed by the compiler or programmer. Archived from the original on From Wikipedia, the free encyclopedia. Internal L1 memory, internal L2 memory, external memory and all memory-mapped control registers reside in this bit address space, so that blwckfin a programming point of view, the Blackfin has a Von Twii architecture.

The Blackfin instruction set contains media-processing extensions to help accelerate pixel-processing operations commonly used in video compression and image compression and decompression algorithms. Instruction memory and data memory are independent and connect to the core via dedicated memory buses, designed for higher sustained data rates between the core and L1 memory.
This memory runs slower than the core clock speed. Reduced instruction set computer RISC architectures. The ISA is designed for a high level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present.
