ADSP-BF538F: 适合工业和外设密集型应用的Blackfin处理器
Blackfin®处理器系列不断扩展，以满足对更多连接方式日益增长的需求。此外，该系列还具有高性能16/32位Blackfin嵌入式处理器内核、灵活的高速缓存架构、增强型DMA子系统以及动态电源管理(DPM)功能。这些新成员与现有Blackfin产品代码兼容，因此系统设计人员可以将处理器内核的综合控制与信号处理能力运用于各种终端应用。ADSP-BF538F处理器扩展了颇受欢迎的ADSP-BF533处理器功能，非常适合需要连接多种设备的应用。ADSP-BF538F的功能与ADSP-BF538处理器相当，但前者还配有片上闪存。该处理器非常适合各类工业、仪器仪表和医疗设备应用。根据最终产品的需求，它可提供多样化连接方式以及控制与信号处理组合功能。
面向嵌入式开发而设计 Blackfin处理器系列的一项新增特性是在处理器旁集成闪存。ADSP-BF538F系列提供两种选择：一种具有512 KB片上闪存，另一种具有1 MB片上闪存。两种型号均提供较大的代码空间，支持复杂的嵌入式系统和快速访问Blackfin内核。此外还有与之互为补充的Blackfin处理器存储器系统，它采用强大而灵活的高速缓存架构，能够动态平衡SRAM所需的硬件实时任务与要求高速缓存功能的软件实时控制任务和操作系统(OS)。
The Blackfin® Processor family has been expanded to address the ever-increasing need for more connection possibilities. This connectivity is coupled with the high performance 16-/32-bit Blackfin embedded processor core, the flexible cache architecture, the enhanced DMA subsystem, and the Dynamic Power Management (DPM) functionality. System designers can take advantage of the combined control and signal processing capabilities of the processor core across a wide range of end applications through code compatibility of these new family members with existing Blackfin offerings.
The ADSP-BF538F processors are a functional extension of the popular ADSP-BF533 processor, and they are ideally suited for applications with multiple device connections. The ADSP-BF538F is equivalent in functionality to the ADSP-BF538 processor with the exception of the addition of onboard FLASH memory. Ideally suited for a broad range of industrial, instrumentation and medical appliance applications-allowing for broad connection possibilities coupled with a mix of control and signal processing needs based on the end product.
Designed for Embedded Development A new addition to the Blackfin Processor family is the inclusion of integrated FLASH memory alongside the processor. There are two choices available in the ADSP-BF538F family, one with 512KB of onboard FLASH memory and one with 1MB of onboard FLASH memory. Both offer large code space for complex embedded systems and fast access time to the Blackfin core. This is in addition to the complementary Blackfin processor memory system that offers a powerful and flexible cache architecture that can dynamically balance between the hard real-time tasks desired in SRAM and soft real-time control tasks and an Operating System (OS) requiring cache functionality.Dynamic Power Management additionally lowers power consumption for extending battery life or for minimizing power dissipation in enclosed applications.
Designed as an Integrated System In addition to the embedded connectivity of CAN, the ADSP-BF538F processors include a variety of general purpose functions designed to minimize external IC count and offer broad control and communication. Peripherals include three SPI®-compatible ports, three UARTs, four SPORT ports, three multifunction timers, 54 general-purpose I/Os, dual Two-Wire Interface for I²C operation, a real-time clock, a watchdog timer, an event controller, and a JTAG/debug interface. The flexible Parallel Peripheral Interface (PPI) offers a direct connection to a variety of video encoders/ decoders, display drivers, image sensors, and general-purpose converters.
