You would have already seen many computers nowadays, which have been developed as embedded systems such that they can be a good option to be used in various electronic appliances including mobiles. micro-controller are actually what serve as the key element in all those embedded systems. micro-controller are also called as microprocessors as well. They are being employed in order to provide more emphasis to both input operations as well as output operations. Moreover, it also takes care of the various operations being carried out by the electronic devices i.e. by offering access to switching information, measurements and communication access. Hence, the microprocessors can also be called controllers of devices. Intel’s 8051 micro-controller and 8052 micro-controller are some of the oldest models offered under the family of micro-controller. However, the popularity of 8051 micro-controller and 8052 micro-controller models has never witnessed a downfall. In fact, the major reason behind the kind of popularity that 8051 micro-controller and 8052 micro-controller enjoy is said to be the architecture as per the technical analysts. In fact, quite a few reputed manufacturers of computers like Atmel, Silicon Labs and NXP as making use of 8051 micro-controller and 8052 micro-controller as the basis of the micro-controller, which they manufacture.

Speaking about the memory structure of 8051 and 8052 micro-controller, it is well designed with a complicated memory structure. Since they are given with a complicated memory structure, of course they will need some special software instructions for accessing them segment wise. In addition, there is a need of some special type of compilers for achieving the accessibility of the memory of 8051 and 8052 micro-controller. Most of the projects and IT industry will make use of compilers that will go compatible with 8051 and 8052 microprocessors. Therefore, it is obvious that there will be quite a few types of embedded C programming compilers available for these micro-controllers. You will of course be able to find these compilers in your local market. Many of them are included in the package accompanied with the IDE (Integrated Development Environment), simulator and debugger. One of the most popular varieties of compilers is called Keil IDE. Similarly, there are also other C programming compilers available even for small devices called Small Device C Compiler (SDCC). This free and one of the most popular compilers is designed to be compatible with Intel 8051, Maxim 80DS390, Motorola 68HC08, Zilog Z80 micro-controller. The SDCC’s open software code is offered based on the guidelines of General Public License (GNU). You can study more about the C languages through C tutorials.

There are only a few Pascal language compilers available for 8051 and 8052 micro-controller, as the Pascal language is rare to witness when it comes to C programming language. To get proficient with the language you also have the option of referring to C tutorials. Some commonly used Pascal language compilers in C tutorials are like KSC Pascal 51 and Turbo 51. The compiler called Turbo 51 is absolutely free and is based on advanced fast multi pass and single pass optimizing technology of the C tutorials. The syntax being used in these compilers is Turbo Pascal 7. Since the options when it comes to Pascal compilers are very less, there is an abundance witnessed in the availability of compilers offered by C tutorials. The major function for which these compilers produced by C tutorials are employed is to produce the codes that must be well optimized for enhancing the size and speed.

Intel Introduces Solid-State Drives for Notebook and Desktop Computers

New Intel(R) High-Performance SATA Solid-State Drive Offers Users Responsive, Rugged, Reliable and Low-Power Storage Solution to Replace Hard Disk Drive

SANTA CLARA, Calif. —(Business Wire)— Sep. 8, 2008 Intel Corporation announced today it has begun shipping Intel(R) X18-M and X25-M Mainstream SATA Solid-State Drives (SSDs) based on multi-level cell (MLC) NAND flash technology for laptop and desktop computers. The new high-performing data storage devices give computer buyers a new level of system responsiveness in a lightweight, rugged, low-power package that can replace traditional hard disk drives.

Validated for Intel-based computers, the X18-M is a 1.8-inch drive and the X25-M a 2.5-inch drive, offering several advantages over hard drives including faster overall system response, boot and resume times. With no moving parts, SSDs run cooler and quieter and are a more reliable option than hard drives. In addition, SSDs remove input/output (I/O) performance bottlenecks associated with hard disk drives that help maximize the efficiency of Intel processors, such as the company’s Core(TM) family of products. For example, lab tests show that the Intel X18-M and X25M increase storage system performance nine times over traditional hard disk drive performance.

“Validated by our rigorous testing and OEM customer feedback, we believe that we have developed an SSD that delivers on the promises of SSD computing,” said Randy Wilhelm, Intel vice president and general manager of the NAND Products Group. “By combining our experience in flash memory design with our processor and computing expertise, we have added advances such as our parallel 10-channel architecture, proprietary controller, firmware and memory management algorithms that address write amplification and wear leveling issues to redefine SSD performance and reliability for computing platforms.”

The Intel X18-M and X25-M Mainstream SATA SSDs are available in 80 gigabyte (GB) capacities, with 160GB versions sampling in the fourth quarter of this year. The 80GB drive achieves up to 250MB per second read speeds, up to 70MB per second write speeds and 85-microsecond read latency for fast performance. The 80GB version is priced at $595 for quantities up to 1,000. These SSDs are available now and end-customer products containing the Intel(R) High-Performance SATA SSDs are expected to begin shipping in the next few weeks.

The company is also expected to introduce a line of single-level cell (SLC) SSDs for the server, storage and enterprise environments within the next 90 days. Called the Intel(R) X25-EExtreme SATA Solid-State Drive, these products are designed to maximize the Input/Output Operations Per Second (IOPS), which equates to higher performance and lower enterprise costs. Since SSDs lower energy consumption, maintenance, cooling and space costs, an SSD-based data center will reduce overall infrastructure costs while increasing performance-per-square-foot by as much as 50x.

The giant semiconductor company has made its debut in the SSD market with an 80GB SSD that is priced at a relatively expensive $595. This new model will come in 1.8″ or 2.5″ sizes that are denoted by the X18-M and X25-M model names.

The SSD world, where actual real-world performance can vary greatly from what’s stated (take everyone upset about the MacBook Air’s SSD, for instance). Intel’s SATA drive is rated for 250MB/s reads and 70MB/s writes, with 85-microsecond latency
