BLACKFIN PROCESSOR PDF

The Blackfin is a family of or bit microprocessors developed, manufactured and marketed by Analog Devices. The processors have built-in, fixed-point. his chapter examines the architecture of the Blackfin processor, which is based on the MSA jointly developed by Analog Devices and Intel. We use assembly. Analog Devices Blackfin /bit Embedded Processors are available at Mouser and offer software flexibility and scalability for convergent applications.

What is regarded as the Blackfin “core” is contextually dependent.

With the optimal code density and the possibility of little to no code optimization, quicker time to market can be achieved without running into performance headroom barriers seen on other traditional processor. The proceszor will intermix glackfin link bit control instructions with bit signal processing instructions into bit groups to maximize memory packing. The Memory Management Unit provides for a memory protection format that, when coupled with the core’s User and Supervisor modes, can support a full Real Time Operating System.

The L1 memory structure has been implemented to provide the performance needed for signal processing while offering the programming ease found in general purpose microcontrollers.

Implementing video compression algorithms in software allows OEMs to adapt to evolving standards and new functional requirements without hardware changes.

Blackfin Processors

Additionally, a single set of development tools can be used, which decreases the system designer’s initial expenses and learning curve. Thus, the MMU offers an isolated and secure environment for robust systems and applications.

Coupled with the core and memory system is a DMA engine that can operate between any of its peripherals and main or external memory. Archived copy as title Articles blaackfin reliable references from December All articles lacking reliable references Articles needing additional references from December All articles needing additional references.

Ultimately, Blackfin Processors will help lower overall system cost while improving the time to market for the end application. These transitions may occur continually under the control of an RTOS or user firmware.

This is accomplished by allowing the L1 memory to be configured as SRAM, cache, or a combination of both. Code and data can be mixed in L2. You can change your cookie settings at any time. Views Read Edit View history. This memory runs slower than the core clock speed.

Transfers can also occur between the peripherals and external devices connected to the external memory interfaces, including the SDRAM controller and the asynchronous memory controller.

The Blackfin uses a byte-addressableflat memory map. Host-target connectivity is provided through a variety of means, depending on the target environment. Blackfin Processors are based on a gated clock core design that selectively powers down functional units on an instruction-by-instruction basis.

The ISA is designed for a high level of expressivenessallowing the assembly programmer or compiler to optimize an algorithm for the hardware features present. The Blackfin Processor family also offers industry leading power consumption performance down to 0.

Circular Buffer Support – The Blackfin Processor compiler can generate circular pointer increments from intrinsic functions or directly from C code. The Blackfin Processor memory architecture provides for both Level 1 L1 and Level 2 L2 memory blocks in device implementations. All Blackfin Processors employ multiple power saving techniques. Superior Code Density The Blackfin Processor architecture supports multi-length instruction encoding.

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 of view, the Blackfin has a Von Neumann architecture. Dynamic Power Management DPM enabling the system designer to specifically tailor the device power consumption profile to the end system requirements. Processor Options – One option for each supported Blackfin model. Blackfin processors contain an array of connectivity peripherals, depending on the specific processor:.

Lastly, and probably most importantly, these embedded microprocessors support a self contained dynamic power management scheme whereby the operating frequency AND voltage can be independently manipulated to meet the performance requirements of the algorithm currently being executed.

The Blackfin Processor architecture blackfkn multi-length instruction encoding. All Blackfin Processors have multiple, independent DMA controllers that support automated data transfers with minimal overhead from the processor core.
