Please improve this by adding secondary or tertiary sources. 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. Please help improve this section by adding citations to reliable sources. This article is about the DSP microprocessor.
The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, Internal L1 memory, internal L2 memory, external memory and all memory-mapped control registers reside in this bit address space, so that from tqi programming point of view, the Blackfin has a Von Neumann architecture.
Coupled with the core and memory system is a DMA engine that can operate between any of its peripherals and main or external blackfinn. Blackfin supports three run-time modes: Computer-related introductions in Instruction set architectures Microcontrollers Digital signal processors.

In supervisor mode, all processor resources are accessible from the running process. These features enable operating systems. ADI provides its own software development toolchains. The Blackfin uses a byte-addressableflat memory map.
This memory runs slower than the core clock speed.

Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions. Retrieved April 9, Retrieved from ” https: For other uses, see Blackfin disambiguation. The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. The ISA is designed for a high level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present.
