Reduced instruction set computer RISC architectures. The Blackfin uses a byte-addressableflat memory map. 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 section does not cite any sources. For other uses, see Blackfin disambiguation. These features enable operating systems. The processors have built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates MACsaccompanied on-chip by a small microcontroller.
Internal L1 memory, internal Blzckfin memory, external memory and all memory-mapped control registers reside in this bit address space, so that from a programming point of view, the Blackfin has a Von Neumann architecture.
They can support hundreds of megabytes of memory in the external memory space. In supervisor mode, all processor resources are accessible from the running process. Views Read Edit View history. ADI provides its own software development toolchains.
Commonly used control instructions are encoded as bit opcodes while complex DSP and mathematically intensive functions are encoded as and bit opcodes. Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. Retrieved April 9, 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.
What is regarded as the Blackfin “core” referenxe contextually dependent. The Blackfin programminf a family of or bit microprocessors developed, manufactured and progrmming by Analog Devices. This memory runs slower than the core clock speed. This blackfn the processor to execute up to three instructions per clock cycle, depending on the level of optimization performed by the compiler or programmer.
The MPU provides protection and caching strategies across the entire memory space. The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, Archived from the original on This article is about the DSP microprocessor.
However, when in user mode, system resources and regions of memory can be protected with the help of the MPU.

If a thread crashes or attempts to access a protected resource memory, peripheral, etc. In other projects Wikimedia Commons. Computer-related introductions in Instruction set architectures Microcontrollers Digital signal processors. Blackfin supports three run-time modes: For some applications, the DSP features are central. The official guidance from ADI on how to use the Blackfin in non-OS environments is to reserve the lowest-priority interrupt for general-purpose code so that all software rdference run in supervisor space.
The ISA is designed for a high level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present. referenfe
