Index of computing articles topic Originally, the word computing was synonymous with counting and calculating, and the science and technology of mathematical calculations.

The chips primarily competed against Intel’s 8-bit family of chips such as theor their relations, the ZiLOG Z80 range. Instructions using the Y register have opcodes prefixed with the byte 0x The 7xx family is also widely used in embedded devices like printers, routers, storage devices, spacecraft,[1] and video game consoles. Data unit Revolvy Brain revolvybrain. During the s and early s, they were popular in personal computers and workstations and were the primary competitors of Intel’s x86 microprocessors.

Motorola’s 68HC11x Family of 8-bit Micro-controllers

Member feedback about In-circuit emulation: The device is not binary compatible with the S08 core, though the instruction opcodes and addressing modes are a subset of the S The instruction set for the 68HC11 processor contain about instructions, 91 of which are new to the 68HC Many components are System-on-a-chip designs tailor made for embedded applications.

Low-power electronics are electronics, such as notebook processors, that have been designed to use less electric power.


It is easy to program in either C or Forth using the customized programming environment, and includes pre-coded device driver libraries and a real time operating system. The family was designed using a hardware description language, making the parts synthesizable, and amenable to improved fabrication processes, such as die shrinks.

Task Switching and Time Keeping. This page is about: This page was last edited on 14 Septemberat With the earlier MC, this was not possible due to a design error in the way the MC treated memory access errors, i. The modules of freescwle microcontroller were designed independently and released as new CPUs could be tested. There was also a small supply of Q This is a list of assemblers: You can 68jc11 values into and read values out of D without ever having to explicitly call A or B, which is why it is this phantom ‘pseudo’ register.

A range of bit instructions treat the A and B registers as a combined bit D register for comparison X and Y registers may also be frwescale to bit memory operandsaddition, subtraction and shift operations, or can add the B accumulator to the X or Y index registers.

Last but not least, the last two registers of interest are the SP and PC registers. The ‘R’ in its part numbers suggests “Reduced”; Freescale itself describes the core as “ultra-low-end”.

Key Challenges and Opportunities — Power. The Motorola series also termed x0, m, m68k, or 68k is a family of bit CISC microprocessors. It does, however, handle an address space of bits from 0x to 0xFFFF.

Each port is eight-bits wide except for D, which is six bits in some variations of the greescale, D also has eight bits. Member feedback about PowerPC: It has freescal eight-bit accumulatorsA and B, two sixteen-bit index registersX and Y, a condition code register, a bit stack pointerand a program counter.


As part of a compiler suite GNU Assembler gas: This manual is laid out in multiple pages, in an order we hope you find most useful. It has two eight-bit accumulatorsA and B, two sixteen-bit index registersX and Y, a condition code register, a bit stack pointerand a program counter.

Most of them are guaranteed for a production lifetime of 10 to 15 years. Using this Doc Web.

Freescale 68HC11 – Wikipedia

The 68HC11 devices are more powerful and more expensive than the 68HC08 microcontrollers, and are used in automotive applications, barcode readers, hotel card key writers, amateur robotics, and various other embedded systems. The resemblances to the HC11 core design are a deliberate move to provide an upgrade path for 68bc11 8-bit 68HC11 designs that require the increased power of a bit CPU.

It operates by using a processor with the additional ability to support debugging operations, as well as to carry out the main function of the system. XC, a prototype of the The Motorola “sixty-eight-oh-twenty”, “sixty-eight-oh-two-oh” or “six-eight-oh-two-oh” is a bit microprocessor from Motorola, released in In other projects Wikimedia Commons.
