A.1 Programming the Watchdog Timer

To program the watchdog timer, you must write a program which writes a value to I/O port address 443 (hex). This output value represents time interval. The value range is from 01 (hex) to FF (hex), and the related time interval is 1 sec. to 255 sec.

Data Time Interval 01 1 sec.

02 2 sec.

03 3 sec.

04 4 sec.

FF 255 sec.

After data entry, your program must refresh the watchdog timer by rewrit- ing the I/O port 443. When you want to disable the watchdog timer, your program should read I/O port 043 (hex). The following example shows how you might program the watchdog timer in BASIC:

10 REM Watchdog timer example program

20 OUT &H443, data REM Start and restart the watchdog 30 GOSUB 1000 REM Your application task #1,

40 OUT &H443, data REM Reset the timer

50 GOSUB 2000 REM Your application task #2,

60 OUT &H443, data REM Reset the timer

70 X=INP (&H043) REM, Disable the watchdog timer

80 END

1000 REM Subroutine #1, your application task

MIC-3358 specifications

The Intel MIC-3358, also known as the Intel Many Integrated Core (MIC) architecture, represents a pivotal innovation in high-performance computing and parallel processing. This product is part of Intel's Xeon Phi family and was specifically designed to tackle demanding workloads, making it a popular choice for research institutions and industries requiring significant computational power.

One of the standout features of the MIC-3358 is its many-core architecture, which integrates numerous processor cores on a single chip. This allows for massively parallel processing capabilities, enabling the execution of multiple tasks simultaneously. With a total of 60 cores, the MIC-3358 can deliver exceptional performance for applications such as scientific simulations, data analytics, and machine learning.

The architecture of the MIC-3358 is notable for its x86 compatibility. Unlike traditional GPUs, the MIC-3358 can run standard x86 applications unmodified, ensuring seamless integration into existing workflows and simplifying development. This feature helps users leverage their existing software tools and libraries without requiring extensive porting or adaptation.

Another key technology is the incorporation of advanced memory architecture, featuring a high-bandwidth memory system. The MIC-3358 supports GDDR5 memory, enabling rapid data transfer rates that are crucial for performance-intensive applications. This, combined with an efficient memory architecture, helps overcome memory bandwidth limitations often encountered in high-performance computing.

The MIC-3358 also includes support for Intel's advanced vector extensions (AVX) and AVX-512, which enhance the processing of vector operations and allow for more efficient data handling. This makes the MIC-3358 particularly effective for workloads that involve large datasets and require complex mathematical computations.

Energy efficiency is another defining characteristic of the MIC-3358. Despite its high core count, the architecture is designed to deliver optimal performance per watt, making it suitable for large data centers where power consumption is a crucial factor.

In summary, the Intel MIC-3358 stands out due to its many-core architecture, x86 compatibility, high-bandwidth memory support, advanced vector instructions, and energy efficiency. These features collectively position it as a powerful solution for high-performance computing challenges, enabling a wide array of applications across various sectors. As the demand for computational resources continues to grow, the MIC-3358 remains a vital component in the landscape of advanced computing technologies.
