Definitions
- go
- Fetch word with slice and tag from LEFT, use bits 3-0 as an index to the color component table, and get the corresponding intensity value. Send the component intensity and slice bitmap RIGHT, and repeat.
- init
- Set register B, and jump to go.
Description
This node receives a word from node 715 with the next character slice bitmap and tag value in the following format:
| - | s | s | s | s | s | - | - | - | - | - | - | - | - | t | t | t | t |
- sssss
- These bits represent five pixels of the current character slice.
- tttt
- Current tag value used as index into color component intensity table.
- -
- Not relevant.
Tag color bits are used as index into the blue color component intensity table, and both character slice and color intensity are sent to node 717.
