Chapter 3: Functional Description
Signals
Table 3–3 shows the RS codeword parameters.
Table 3–3. RS Codeword Parameters
Parameter
Number of bits per
symbol
Number of symbols per
codeword
Number of check symbols
per codeword
Range
3 to 12
5 to (2 m – 1)
2 to min(128, N – 1)
Range
(Continuous)
6 to 12
7( R + 1) to 2 m – 1
4 to N /7 – 1
Description
Specifies the number of bits per symbol ( m ).
Specifies the total number of symbols per
codeword ( N ).
Specifies the number of check symbols per
codeword ( R )
Field polynomial
First root of generator
polynomial
Root spacing in generator
polynomial
Any valid polynomial
0 to (2 m – 2)
Any valid root space
(1)
(1)
Specifies the primitive polynomial defining the
Galois field.
Specifies the first root of the generator polynomial
( i 0 ).
Specifies the minimum distance between roots in
the generator polynomial ( a ).
Notes to Table 3–3 :
(1) IP Toolbench allows you to select only legal values. For m > 8, not all legal values of the field polynomials and rootspace are present in IP
Toolbench. If you cannot find your intended field polynomial or rootspace in the IP Toolbench list, contact Altera MySupport.
Signals
Table 3–4 shows the global signals.
Table 3–4. Global Signals
Name
clk
reset
Description
clk is the main system clock. The whole MegaCore function operates on the rising edge of clk .
Reset. The entire decoder is asynchronously reset when reset is asserted high. The reset signal resets the
entire system. The reset signal must be de-asserted synchronously with respect to the rising edge of clk .
