Views Read Edit View history. Blackfin processors contain an array of connectivity peripherals, depending on progrwmming specific processor:. They can support hundreds of megabytes of memory in the external memory space. The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. Archived from the original on For other uses, see Blackfin disambiguation.
The Blackfin architecture encompasses various CPU models, each targeting particular applications. This article relies too much on references to primary sources. This article is about the DSP microprocessor. This page was last edited on 14 Septemberat Computer-related introductions in Instruction set architectures Microcontrollers Digital signal processors. What is regarded as the Blackfin “core” is contextually dependent. 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.
Internal L1 memory, internal L2 memory, external memory proggamming 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.

The processors progrramming built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates MACsaccompanied on-chip by a small microcontroller. Reduced instruction set computer RISC architectures.
If a thread crashes or attempts to access a protected resource memory, peripheral, etc. 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.
Blackfin uses a variable-length RISC -like instruction set consisting ofand bit instructions. This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures.
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 run in supervisor space. The Blackfin uses a byte-addressableflat memory map. The MPU provides protection and caching strategies across blackrin entire memory space. Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions.
These features enable operating systems. Retrieved from ” https: Please improve this by adding secondary or tertiary sources. Unsourced material may be challenged and removed.
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. Blackfin supports three run-time modes: However, when in user mode, system resources and regions of memory can be protected with the help of the MPU. All of the peripheral refrence registers are memory-mapped in the normal address 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.
