Abstract: This application note discusses the development and deployment of 3G cellular femtocell base stations. The technicalchallenges for last-mile residential connectivity and adding system capacity in dense urban environments are discussed, with 3Gfemtocell base stations as a cost-effective solution. Maxim's 3GPP TS25.104-compliant transceiver solution is presented along withcomplete radio reference designs such as RD2550. For more information on the RD2550, see reference design 5364, "FemtocellRadio Reference Designs Using the MAX2550–MAX2553 Transceivers."

The project KEIL_IODemo shows how to use memory allocation routines (malloc) and char I/O (printf, scanf) via a serial interface with the Keil ARM toolchain. The I/O functions are adapted for the Analog Devices ADuC7000 series using the SERIAL.C module. The example also shows the efficiency of the Keil CA ARM Compiler run-time library which is tuned for single chip systems.

UART I/O and Memory Allocation Example for GNU The project GNU_IODemo shows how to use memory allocation routines (malloc) and char I/O (printf, scanf) via a serial interface with the GNU toolchain. The I/O functions are adapted for the Analog Devices ADuC7000 series using the SERIAL.C module. The example also shows the efficiency of the Keil CA ARM Compiler run-time library which is tuned for single chip systems.

ST7787 芯片的SPEC，比亚迪2.4inchLCM的SPEC。The ST7787 is a Single-Chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and 320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the on-chip display data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.

The TMS320LF240xA and TMS320LC240xA devices, new members of the TMS320C24x generation of digital signal processor (DSP) controllers, are part of the TMS320C2000 platform of fixed-point DSPs. The 240xA devices offer the enhanced TMS320 DSP architectural design of the C2xx core CPU for low-cost, low-power, and high-performance processing capabilities. Several advanced peripherals, optimized for digital motor and motion control applications, have been integrated to provide a true Single-Chip DSP controller. While code-compatible with the existing C24x DSP controller devices, the 240xA offers increased processing performance (40 MIPS) and a higher level of peripheral integration. See the TMS320x240xA Device Summary section for device-specific features.

The XC226x derivatives are high-performance members of the Infineon XC2000 Family of full-feature Single-Chip CMOS microcontrollers. These devices extend the functionality and performance of the C166 Family in terms of instructions (MAC unit), peripherals, and speed. They combine high CPU performance (up to 80 million instructions per second) with extended peripheral functionality and enhanced IO capabilities. Optimized peripherals can be adapted flexibly to meet the application requirements. These derivatives utilize clock generation via PLL and internal or external clock sources. Onchip memory modules include program Flash, program RAM, and data RAM.

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)。

A programmable digital signal processor (PDSP) is a special-purpose microprocessor with specialized architecture and instruction set for implementing DSP algorithms. Typical architectural features include multiple memory partitions (onchip, off-chip, data memory, program memory, etc.), multiple (generally pipelined) arithmetic and logic units (ALUs), nonuniform register sets, and extensive hardware numeric support [1,2]. Single-Chip PDSPs have become increasingly popular for real-time DSP applications [3,4].
