NXP LPC

LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors (formerly Philips Semiconductors). The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each microcontroller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. The earliest LPC series were based on the Intel 8-bit 80C51 core. As of February 2011, NXP had shipped over one billion ARM processor-based chips.

Overview

All recent LPC families are based on ARM cores, which NXP Semiconductors licenses from ARM Holdings, then adds their own peripherals before converting the design into a silicon die. NXP is the only vendor shipping an ARM Cortex-M core in a DIP package: LPC810 in DIP8 (0.3-inch width) and LPC1114 in DIP28 (0.6-inch width). The following tables summarize the NXP LPC microcontroller families.

Pike (programming language)

Pike is an interpreted, general-purpose, high-level, cross-platform, dynamic programming language, with a syntax similar to that of C. Unlike many other dynamic languages, Pike is both statically and dynamically typed, and requires explicit type definitions. It features a flexible type system that allows the rapid development and flexible code of dynamically typed languages, while still providing some of the benefits of a statically typed language.

Pike features garbage collection, advanced data types, and first-class anonymous functions, with support for many programming paradigms, including object-oriented, functional and imperative programming. Pike is free software, released under the GPL, LGPL and MPL licenses.

History

Pike has its roots in LPC, which was a language developed for MUDs. Programmers at Lysator in Linköping, Sweden, most notably Fredrik Hübinette and Per Hedbor, separated the language and virtual machine from the rest of the MUD driver, and used it as a rapid prototyping language for various applications, calling it LPC4.

LPC (programming language)

LPC (short for Lars Pensjö C) is an object-oriented programming language derived from C and developed originally by Lars Pensjö to facilitate MUD building on LPMuds. Though designed for game development, its flexibility has led to it being used for a variety of purposes, and to its evolution into the language Pike.

LPC syntax places it in the family of C-like languages, with C and C++ its strongest influences.

Basic structure

Almost everything in LPC is an object. However, LPC does not precisely use the concept of a class (MudOS has something called a class, but it is really a struct). Instead, LPC objects are blueprint objects and clones of blueprint objects, in a prototype-based programming model. One can treat a blueprint object much as a class in other object-oriented languages.

Each object has variables (attributes) and functions (methods). The variables store the object's state; the functions are executable routines that can be called in the object. An object is uniquely defined by the name of the file in which it comes from, plus, if a clone, a numeric identifier. In a typical implementation, a clone of the file /lib/weapon.c which is the third clone created in the current run session will be /lib/weapon#3. The blueprint object corresponding to /lib/weapon.c is simply /lib/weapon. In a MUD game, common objects include rooms, weapons, armor, and non-player character (NPCs). Most mudlibs define inheritable objects for such common things. In the LPMud 2.4.5 mudlib, for example, the parent object for all rooms is /lib/room.

NXP Semiconductors

NXP Semiconductors N.V. is a global semiconductor manufacturer headquartered in Eindhoven, The Netherlands. The company employs approximately 45,000 people in more than 35 countries, including 11,200 engineers in 23 countries.NXP reported revenue of $6.1 billion in 2015, including one month of revenue contribution from recently acquired Freescale Semiconductor.

NXP is currently the fifth-largest non-memory semiconductor supplier globally, and the leading semiconductor supplier for the Secure Identification, Automotive and Digital Networking industries respectively.The company was founded in 1953, with manufacturing and development in Nijmegen, Netherlands. Known then as Philips Semiconductors, the company was sold to a consortium of private equity investors in 2006, at which point the company's name was changed to NXP.

On August 6, 2010, NXP completed its IPO, with shares trading on NASDAQ under the ticker symbol NXPI. On December 23, 2013, NXP Semiconductors was added to the NASDAQ 100.Finally, on March 2, 2015, it was announced that NXP Semiconductors would merge with chip designer and manufacturer Freescale Semiconductor in a $40 billion US-dollar deal. The merger was closed on December 7, 2015.
