Tests and Diagnostics

With regard to the test memory content, save the data to the test memory before the test and restore it to the former address after the test. (Coincidence assurance of the memory content)

Details of Test

Step 1: Sequential Write (Fixed pattern 1 MMX version 00005555AAAAFFFFh） : Sequential Read and Compare

Step 3: Sequential Write (Fixed pattern 2 MMX version FFFFAAAA55550000h）

: Sequential Read and Compare

Step 5: JMP + Write (Address pattern 1) 0, 1/2 increment 1//4, 3/4 decrement : JMP + Read and Compare

Step 7: JMP＋Write (Address pattern 2) 1/4. 3/4 increment 0, 1/2 decrement

:JMP＋Read and Compare

3)Cache memory (On / off)

This subtest writes constant data to constant address 70000h in the protected mode, then reads the written data and compares the result with the original data.

With regard to the test memory content, save the data to the test memory before the test and restore it to the former address after the test. (Coincidence assurance of the memory content) Details of Test:

This subtest displays the number of memory accesses within the same time in both of Cache ON and Cache OFF by the counter. Check that the benchmark speed is high when the cache is used

4) Stress

This subtest writes or reads constant data and address data from 1MB to the maximum MB in the protected mode and compare the results with the original data.

For the content of the test memory, save the data to the test target memory before the test and restore it to the former address after the test.

Details of Test:

This subtest is performed once from step 1 to step 3 and repeated 20 times from step 5 to step 8 and then it displays the total number of the test performances as Sub Step Number.

Step 1: Sequential Write (Fixed pattern 1 MMX version 00005555AAAAFFFFh） : Sequential Read and Compare

Step 3: Sequential Write (Fixed pattern 2 MMX version FFFFAAAA55550000h） : Sequential Read and Compare

Step 5: JMP + Write (Address pattern 1) 0, 1/2 increment 1/4, 3/4 decrement

Z830 specifications

The Toshiba Z830, a part of the Satellite range, made its mark in the ultra-portable laptop category when it was launched. Designed for users searching for a blend of performance, portability, and style, the Z830 stood out for several reasons.

One of the most prominent features of the Toshiba Z830 is its ultra-thin and lightweight design. Weighing in at just over 2.5 pounds and measuring less than 0.7 inches in thickness, it was one of the lightest laptops available at its time, making it an ideal choice for frequent travelers and mobile professionals. The chassis is built from a strong magnesium alloy that contributes to its durability while maintaining a sleek silhouette.

Display-wise, the Toshiba Z830 boasts a 13.3-inch LED-backlit display with a resolution of 1366x768 pixels. The screen offers good color reproduction and brightness, providing an adequate experience for productivity tasks and media consumption. The incorporation of an anti-glare finish reduces reflections, further enhancing usability in various lighting conditions.

In terms of performance, the Z830 is powered by Intel's third-generation Core processors, with options ranging from i3 to i7, depending on the configuration. This enables users to run applications smoothly, whether for business tasks, multitasking, or media editing. Accompanying the processors is a solid-state drive (SSD), which provides quick boot times and faster data access compared to traditional hard disk drives.

Connectivity options are abundant in the Toshiba Z830, featuring USB 3.0 ports, HDMI output, and an SD card reader. Additionally, it includes a full-sized keyboard which is comfortable for typing, and a responsive touchpad that supports multi-touch gestures.

On the technological front, the Z830 integrates Wi-Fi and Bluetooth capabilities, ensuring users stay connected whether at home or on the go. The laptop also incorporates Toshiba’s Sleep and Charge technology, allowing users to charge their devices through USB while the laptop is in sleep mode, a convenient feature for those on the move.

Battery life is another strong aspect of the Toshiba Z830, with the ability to last for several hours on a single charge, depending on usage. This makes it suitable for long flights or extended working sessions without the constant need for a power source.

In conclusion, the Toshiba Z830 combines a portable design with robust performance, making it a commendable choice for professionals and students alike. Its blend of advanced features, connectivity options, and user-friendly design underline its reputation as a reliable ultra-portable laptop in its era.
