Blackfin supports three run-time modes: ADI provides its own software development toolchains. This section does not cite any sources.
Please help improve this section by adding citations to reliable 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.
Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. December Learn how and when to remove this template message.
Blackfin Processors: Manuals
This memory runs slower than the core clock speed. The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, 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. 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.
Archived from the original on In supervisor mode, all processor resources are accessible from the running process. If a thread crashes or attempts to access a protected resource memory, peripheral, etc.
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. All of the peripheral control registers are memory-mapped in the normal address space. The Blackfin is a family of blackrin bit microprocessors developed, manufactured and marketed by Analog Devices.
The Blackfin uses a byte-addressableflat memory map. The processors have built-in, fixed-point digital signal processor DSP functionality supplied by programmjng multiply—accumulates MACsaccompanied on-chip by a small microcontroller. The MPU provides protection and caching strategies across the entire memory space.
Blackfin – Wikipedia
Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions. Coupled with the core and memory system is a DMA engine that can operate between any of its peripherals and main or external memory. Instruction memory prograkming 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.

The Blackfin architecture encompasses various CPU models, each targeting particular applications. The official guidance from ADI on how to use the Blackfin in non-OS environments is to reserve the lowest-priority refeeence for general-purpose code so that all software is run in supervisor space.

Internal L1 memory, internal L2 memory, external memory and all memory-mapped control registers reside in this bit address space, so that from a programming point pdogramming view, the Blackfin has a Von Neumann architecture.
This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures.
