Bit-a-Bit Store

Group 14's project submission for the Computer Architecture course at Unical (A.A. 2022/23).

The app is written in ARM assembly, but calls some functions from libc.

Compile and run the app

On GNU/Linux x86_64 you need aarch64-linux-gnu-gcc (for Arch and Debian) e qemu-user-binfmt (for Debian) o qemu-user (for Arch), then run:

aarch64-linux-gnu-gcc -static bit-a-bit_store.s -o bit-a-bit_store
qemu-aarch64 bit-a-bit_store

The app

At startup the user is presented a table and an action prompt. The rows of the table represent products of a tech store, each one described by some fields.

The data are stored in a file entries.dat. The action that can be executed on the data are:

• add a new product, typing each field from the terminal
• remove a product based on its position
• filter the products
  • by price (between to price extremes)
  • by type
• swap two products based on their position
• remove the first product with the same price as the one following it
• swap the first two products not sorted in increasing order for the stocks field
• sort the whole table by stocks in increasing order
• compute the floating point average of the products prices.
