Introduction
This program is a sample of the scheduler program. The scheduler
used in this sample program was developed by the Nintendo 64 Technical
Support Center and has the usual scheduler functions. It can be
improved and expanded to function with reasonably good efficiency,
so please use this scheduler as a reference.
make
Use make with with either the Indy Emulator Board or Partner-N64NW.
It is used without changes to either device.
Note: (1) The F3DEX microcode must be used with this sample program.
(2) The comments in the source file use Shift-JIS encoding.
Operation

Screen Description
(1) Number of Polygons in Models
Fighter No. 1 blue): 314 Triangles
Fighter No. 2 red): 314 Triangles
(2) Performance Meter Perspective
The Performance Meter frames are the first, second,
and third frames from the left. The meters are as follows.
Red Processing time for audio tasks
Green RSP processing time for graphics tasks
Yellow RDP processing time for graphics tasks
Included in the RSP processing time is YIELD time resulting
from audio tasks.
(3) Screen Rendering
With screen rendering, the following 3 graphics tasks
are initiated for each frame.
1. Clearance of the frame buffer and Z buffer (F3DEX microcode)
2. Rendering of opaque polygons (F3DEX microcode)
3. Line rendering �i(Line3D microcode)
Frame buffer and Z buffer clearance and opaque polygon
rendering are separated because they are performed
during the time the CPU creates audio tasks.
Rights and Program Re-use
The copyright for this sample program is held by Nintendo Co., Ltd.
Although the source code can be freely re-used and modified, this
program has not been adequately debugged. We, therefore, urge you
