Bit test operations have also been added, performing a logical AND function between operands, setting the correct conditions codes, but not modifying the operands.

With the earlier MC, this was not possible due to a design error in the way the MC treated memory access errors, i. This manual is geared to the C programmer. There was also a small supply of Q The HC16 provides a software upgrade path for HC11 users while giving full hardware compatibility with the asynchronous address and data bus found on the bit microprocessors.

Electric power Revolvy Brain revolvybrain. In combination with a MC the MC permitted the realization of virtual memory. Index of computing articles topic Originally, the word computing was synonymous with counting and calculating, and the science and technology of mathematical calculations.

Convenient connectors allow for simple mechanical integration.

In keeping with naming practices common to Motorola designs, the is usually referred to as 68bc11 “”, pronounced “oh-two-oh” or “oh-twenty”. Motorola and Freescale’s proper name of this family of processors is PowerPC 74xx. The HEX file is then imported by a programmer to “burn” the machine code into non-volatile memory, or is transferred to the target system for loading and execution.


Key Challenges and Opportunities — Power. Note that NXP and Freescale merged in Also, floating point intermediates are 64 bits and not 80 bits as in the and coprocessors. The was the successor to the Motorolaand freescalw followed by the Motorola This family has five CPU registers that are not part of the memory: Member feedback about Freescale S Contact us for technical help or just to chat.

This is a list of assemblers: However, it was still faster than competing 8-bit microprocessors, because the internally was based on bit data registers and a bit data bus. Principles and ApplicationsPearson Higher Ferescale.

It does, however, handle an address space of bits from freescale to 0xFFFF. Low-power electronics are electronics, such as notebook processors, that have been designed to use less electric power.

Motorola topic This article is based on material taken from the Free On-line Dictionary of Computing prior to 1 November and incorporated under the “relicensing” terms of the GFDL, version 1. The family was designed using a hardware description language, making the parts synthesizable, and amenable to improved fabrication processes, such as die shrinks.

These ‘I’ which stands for Index registers contain memory addresses, used to store values into and read values from memory. The was also used freescale other personal computers, such as th Member feedback about Freescale DragonBall: It includes their operation and usage, the electrical processes carried out within the computing hardware itself, and the theoretical concepts governing them computer science.


PowerQUICC processors are used in networking, automotive, industrial, storage, printing and consumer applications. The architecture of the 68HC11 micro-contoller is very basic.

In practice, these additional chips required more space on the circuit board and the buses between the MCs and MC added complexity and cost.

The ‘s ALU was also natively bit, so could perform bit operations in one clock, whereas the took two clocks minimum due to its bit ALU.

In-circuit emulation topic In-circuit emulation ICE is the use of a hardware device or in-circuit emulator used to debug the software of an embedded system. By far the most common use for a 68HC11 micro-controller is as a processor for small robots. See the presenation area for more details. This partitioned scheme was chosen to provide system flexibility, the amount of cache could be varied fdeescale on the price point.

Other hex formats There are othe A lower cost version was also made available, known as the 68EC Although no modern desktop computers are based on processors in the series, derivative freesvale are still widely used in embedded systems.
