单片微型计算机是微型计算机发展中的一个重要分支,是把构成一台微型计算机的主要部件如中央处理器(CPU)、存储器(RAM/ROM)和各种功能I/O接口集成在一块芯片上的单芯片微型计算机(Single Chip Micro Computer),简称单片机.由于它的结构与指令功能都是按工业控制要求设计的,且近年来单片机着力扩展了各种控制功能如A/D、PWM等,因此我们更多时候称其为一个单片形态的微控制器(Single Chip Micro Controller),或直接称其为微控制器(Micro Controller)。

NCO 在信号处理方面有着广泛的应用。而函数发生器是NCO 中的关键部分,本文基 于FPGA 用状态机和流水线方法实现了CORDIC 算法,并取代了传统的ROM 查找表法。 最后通过Quartus II 软件给出仿真结果,验证了理论的正确性。

SCSI Multimedia Commands 鈥?3 (MMC-3) T10/1363-D 5.16 READ CAPACITY Command The READ CAPACITY command (Table 144) provides a means for the Initiator to request information regarding the capacity of the Logical Unit. This command shall not report the correct capacity of the recorded data for CD-R, CD-RW and DVD-R/-RW media that does not have a Lead-out in the last Session or last Border-out. For CD-ROM, the returned logical block address is modified to allow returning a possibly inexact value (but one with a known error bound) based on the Table of Contents data

The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4- bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the W78E58B allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security

在TI DSP的开发环境CCS(Code Composer Studio)下,PC机通过JTAG电缆与用户目标系统中的DSP通信,帮助用户完成调试工作。当用户在该环境下完成开发任务,编写完成用户软件之后,到DSP目标系统产品化阶段时,需要完全脱离依赖PC机的CCS环境,并要求目标系统上电后可自行启动并执行用户软件代码,这就需要用到自启动(Bootloader)技术。同时Bootloader也指由TI在生产DSP芯片时预先烧制其片内ROM中,完成该功能的一段代码名称。
