tructure and Implementation 5.Lesson Learned and Advice for Future work

Bat t le cit y game on S

• ckit board

Inspired by t he classic t ank game –

bat t le cit y

Rules of t he game

for winning t he game:

• - shot off all t he enemy t anks

for losing t he game:

• - Enemy t anks are not wiped off aft er reborn t wo t imes
• - homebase is damaged no mat t er who shoot it .

VGA display

• -VGA controller
• -VGA map
• -VGA display

Audio

• - I2C Bus Controller
• -Audio Codec Controller
• -Audio Data Controller

VGA display

Image processing and st oring

• -All images t hat are st ored int o t he ROM can be

cat egorized int o t hree sizes: 0.25KB, 1KB and 64KB.

• -Image cat egories:

Background, t ank, welcome and game over screen and Display Effect s.

• -All images are loaded from t he ROM and t he

posit ion of displaying is sent from soft ware.

VGA display

VGA cont roller

• -different t ypes of sprit es have different locat ions

and mot ions and t hey should be displayed on t he screen at t he same t ime.

• -VGA cont roller is designed t o cont rol t he display of

different sprit es, including order, locat ion, direct ion and changing map.

• -Wit h VGA cont roller, it is easier for us t o add or

delet e or move t he sprit es by soft ware.

Audio

• - 11.2896 MHz Audio Module Working frequency (Table

30 from audio codec dat asheet )

* Creat ing a 11.2896MHz clock generat or by

Megawizard

• - Two-t rack 16 bit 44.1KHz sampling rat e audio effect s

*S

t ored in on-chip memory

Audio

I2C Cont roller

• - Configure t he ent ire audio syst em like left and

right channel playing and recording

• - R2 & R3: 0dB volume amplificat ion for bot h

channel

• - R8: 44.1KHz S

Audio Codec Cont roller

• - Divide 11.2896MHz Working frequency t o 44.1KHz

Dat a reading rat e (S ampling Rat e)

Global Bullet moving Bullet map Tank moving Tank map Gamecontroller Explosion

Global

Record all macro definitions for the whole proj ect

Gamecontroller

Record all keycodes information for different

button on the j oysticker.

Tank moving and tank map

• - Generating our tanks and moving them

according to information from j oysticker.

• - Generating enemy tanks and moving them

according to random information.

• - Judge whether the bullet meet a brick or not
• - Judge whether tank meets obstacles or not
• - If a bullet meet part of the brick, update the

map so that tank can move over that place.

Bullet moving and bullet map

• - Generating the bullet according to the

direction of tank

• - Judge whether the bullet meet a tank or not
• - Judge whether two bullets meet or not
• - If a bullet meet part of the brick, update the

map

Explosion

If a tank is shot off, beginning the two steps of explosion

Design architecture of hardware and software

for the FPGA board to run the whole proj ect.

Use Qsys to help with hardware design. Resources allocation when designing the

hardware due to the limited resources on the board.
