This variable length opcode encoding is designed for code density equivalence to modern microprocessor architectures.
The ISA is designed for a high level of expressivenessallowing hlackfin assembly programmer or compiler to optimize an algorithm for the hardware features present. The Blackfin uses a byte-addressableflat memory map.
The Blackfin instruction set contains media-processing rdference to help accelerate pixel-processing operations commonly used in video compression and image compression and decompression algorithms. Blackfn provides its own software development toolchains. 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.
Commonly used control instructions are encoded as bit opcodes while complex DSP and mathematically intensive functions are encoded as and bit opcodes.

The architecture was announced in Decemberand first demonstrated at the Embedded Systems Conference in June, Two nested zero-overhead loops rfeerence four blcakfin buffer DAGs data address generators are designed to assist in writing efficient code requiring fewer instructions.
The processors have built-in, fixed-point digital signal processor DSP functionality supplied by bit multiply—accumulates MACsaccompanied on-chip by a small microcontroller. Retrieved April 9, The MPU provides protection and caching strategies across the entire memory space.

Blackfin uses a variable-length RISC -like instruction set consisting ofand bit instructions.
The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. However, when in user mode, system resources and regions of memory can be protected with the help of the MPU. For some applications, the DSP features are central. The processors typically have a dedicated DMA channel for each peripheral, which is designed for higher progdamming for applications that can use it, such as real-time standard-definition D1 video encoding and decoding.
Archived from the original on April 17, Retrieved from ” https: Views Read Edit View history. 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.
Reduced instruction set computer RISC architectures. Computer-related introductions in Instruction set architectures Microcontrollers Digital signal processors. This memory runs slower than the core clock speed.
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.
