The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.

多维多选择背包问题(MMKP)是0-1背包问题的延伸,背包核已经被用来设计解决背包问题的高效算法。目的是研究如何获得一种背包核,并以此高效处理多维多选择背包问题。首先给出了一种方法确定MMKP的核,然后阐述了利用核精确解决MMKP问题的B&B算法,列出了具体的算法步骤。在分析了算法的存储复杂度后,将算法在各种实例上的运行效果与目前解决MMKP问题的常用算法的运行效果进行了比较,发现本文的算法性能优于以往任何算法。
