PicoBlaze

[trafo]

Hi,

I'm new to PicoBlaze and i'm trying to understand basic things.

My questions is; What is the "05" in second line stands for? Is it of 5th bit of s0?

INPUT s0, input_port
TEST s0, 05

And again in this line, is "80" value of this constant?

CONSTANT LED7, 80    

Sorry for these questions but i dont have person around me to learn that basic stuffs. Also internet resources are too high-level and cosidering me as knowing them.

Thank you.

I suggest that you read the PicoBlaze documentation. You did not state if you are using KCPSM3 or KCPSM6 but both describe these fundamental items.

For example, for KCPSM3 then see....

http://www.xilinx.com/support/documentation/ip_documentation/ug129.pdf

Page 28 and page 29 dscribes the TEST instruction and even shows an example using values '04' and '05'.

Page 72 describes the CONSTANT directive.

If you can't understand the documentation provided with KCPSM3 and/or KCPSM6 then please return forum and ask more questions referencing the exact parts of of the documentation you need help with.

See UG129 version 2.0, Table 3-1, page 18.  Then see section starting on page 28.

And again in this line, is "80" value of this constant?

CONSTANT LED7, 80   

See UG129 version 2.0, page 72: Defining Constants
