Q2 Internal Buffers

The Q2 has three internal buffers—a command buffer, source buffer, and work buffer—as shown in
figure 6-5.

Figure 6-5 Updating of Q2’s Internal Buffers

These buffers are used by the Q2 to temporarily store data held in the UGM. The Q2 uses the data
stored in these buffers when executing drawing.

The functions of these buffers are shown in (a) to (c) below.

(a) Command buffer: Used by the Q2 to store a display list held in the UGM
(b) Source buffer: Used by the Q2 to store a binary source or multi-valued source held in the UGM
(c) Work buffer: Used by the Q2 when performing drawing at binary work coordinates in the UGM

The size of these buffers is fixed: 16 words each for the command buffer and source buffer, and 4
words for the work buffer.
