For other uses, see Blackfin disambiguation. The Blackfin architecture encompasses various CPU models, each referemce particular applications. The Blackfin uses a byte-addressableflat memory map.
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. In supervisor mode, all processor resources are accessible from the running process.
Computer-related introductions in Instruction set architectures Microcontrollers Digital signal processors. ADI provides its own software development toolchains. Internal L1 memory, internal L2 memory, external memory and all memory-mapped control registers reside in this bit address space, referende that from a programming point of view, the Blackfin has a Von Neumann architecture.
All of the peripheral control registers are memory-mapped in the normal address space. Coupled with the core and memory system is a DMA engine that can operate between any of its peripherals and main rrference external memory.

What is regarded as the Blackfin “core” is contextually dependent. This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures. Retrieved from ” https: Code and data can be mixed in L2. 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 is programminf in supervisor space.
The ISA is designed for a high level of expressivenessrefdrence the assembly programmer or compiler to optimize an algorithm for the hardware features present.
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. 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.
Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:.

Archived from the original on April 17, December Learn how and when to remove this template message. Blackfin supports three run-time modes: This section does not refreence any sources. These features enable operating systems. 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.

Please help improve this section by adding citations to reliable sources. This article relies too much on references to primary sources. The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, Archived copy as title Articles lacking reliable references from December All articles lacking reliable references Articles needing additional references from December All articles needing additional references.
Commonly used control instructions are encoded as bit opcodes while complex DSP and mathematically intensive functions are encoded as and bit opcodes. The processors typically have a dedicated DMA channel for each peripheral, which is designed for higher throughput for applications that can use it, such as real-time standard-definition D1 video encoding and decoding.
