This article relies too much on references to primary sources. The processors have built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates MACsaccompanied on-chip by a small microcontroller. Coupled with the core rdference memory system is a DMA engine that can operate between any of its peripherals and main or external memory.


Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:. 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.

They can support hundreds of megabytes of memory in the external memory 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.

Retrieved from ” https: The Blackfin uses a byte-addressableflat memory map. 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.

Retrieved April 9, 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. This section does not cite any sources. However, when in user mode, system resources and regions of memory can be protected with the help of the MPU. The Blackfin architecture encompasses various CPU models, each targeting particular applications. Unsourced material may be challenged and removed.


Blackfin supports three run-time modes: Reduced instruction set computer RISC architectures. Two nested zero-overhead loops and four circular buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions. In supervisor mode, all processor resources are accessible from the running process.

Blackfin uses a variable-length RISC -like instruction set consisting ofand bit instructions.

This variable refefence opcode encoding is designed for code density equivalence to modern microprocessor architectures. 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. All of the peripheral control registers are memory-mapped in the normal address space.
