详细信息
1756-TBCH /1756-TBCH AB是一种执行较少类型计算机指令的微处理器,起源于80 年代的MIPS主机(即RISC 机),RISC机中采用的微处理器统称RISC处理器。这样一来,它能够以更快的速度执行操作(每秒执行更多百万条指令,即MIPS)。因为计算机执行每个指令类型都需要额外的晶体管和电路元件,计算机指令集越大就会使微处理器更复杂,执行操作也会更慢。STM32F100VBT6采用ARM Cortex-M3 32位RISC内核,工作频率24MHz,集成了高速嵌入式存储器(闪存高达128kB、SRAM高达8kB)以及各种增强外设和连接到两条APB总线的I/O。所有器件提供两个I2C、两个SPI、一个HDMI CEC和多达3个USART标致通信接口以及一个12位ADC、两个12位DAC和六个通用16位定时器和PWM定时器。
1756-TBCH /1756-TBCH AB微处理器不仅精简了指令系统,采用超标量和超流水线结构;它们的指令数目只有几十条,却大大增强了并行处理能力。SGI公司推出的MIPS处理器则采用超流水线结构,这些RISC处理器在构建并行精简指令系统多处理机中起着核心的作用。
