<h2>Description</h2>
<p>Block TEST_GEB is designed to generation the test sequence.</p>
<p>The algorithm works:</p>
<ul>
<li>reset: <span lang="en-us">
<a href="#Регистр TEST_GEN_CTRL">TEST_GEN_CTRL</a></span>[RESET]=1, <span lang="en-us">
<a href="#Регистр TEST_GEN_CTRL">TEST_GEN_CTRL</a></span>[RESET]=0</li>
<li>set mode: <span lang="en-us">
<a href="#Регистр TEST_GEN_CTRL">TEST_GEN_CTRL</a></span>[FIX_MODE,
BLOCK_MODE], CNT1, CNT2 </li>
<li>program and start DMA controller in the PE_EXT_FIFO block</li>
<li>start: <span lang="en-us">
<a href="#Регистр TEST_GEN_CTRL">TEST_GEN_CTRL</a></span>[START]=1 - enable
to DMAR</li>
</ul>
<p>The test sequence is a set of data blocks.<br>
The block size is specified multiple of the size of 4 kilobytes<br>
(512 words by 64 bits)<br>
The first 64-bit word in the block contains the signature and serial number:</p>
<ul>
<li>31 .. 0 - signature 0xA5A50123</li>
<li>63 .. 32 - serial number of the unit</li>
</ul>
<p>Contents of the block depends on its number in the sequence.<br>
<br>
The contents of the data block:</p>
<ul>
<li>0 - Running the unit on the 64th bits</li>
<li>1 - Running zero on the 64th bits</li>
<li>2 - Running the unit with an inversion of the 64-th digit<br>
- Even numbers of words - running the unit on the 64th bits<br>
- Odd numbers - inversion previous word</li>
<li>3 - Running with zero inversion ranks 64th<br>
- Even numbers - running zero to 64-th digit<br>
- Odd numbers - inversion previous word</li>
<li>4 - Running in the unit block<br>
Word number is compared with the number of units (compare lower eight
bits)<br>
At coincidence - in the Word is running 1.<br>
Other words - zero.</li>
<li>5 - Running a zero in the block<br>
Word number is compared with the number of units (compare lower eight
bits)<br>
At coincidence - in the Word is running 0.<br>
Other words - value 0xFFFFFFFFFFFFFFFF.</li>
<li>6.7 - Counter on the 64th bits<br>
- Even numbers - count<br>
- Odd numbers - inversion previous word</li>
<li>8.9 - The pseudo-random sequence<br>
Formed M-sequence of 64 bits.<br>
The initial value of - 1<br>
The word is formed shift by one bit to the left.<br>
In LSB words recorded value of x[63] xor x[62] xor x[60] xor x[59]</li>
</ul>
