Скачать или смотреть Introduction to Virtual Processor

This is a brief video introducing the different data path elements and how they are connected to each other. I will hit some key points about the processor architecture but will not be going into much depth. The purpose of this video is familiarize viewers with the locations and basic concept of the processor elements so that future videos are understandable. This is not a demonstration of operation.

For reference, the processor has:
5 bit program counter for instruction memory of size 32
7 bit instructions
4 8bit registers ($1- $3 plus a $0)
8 8bit memory locations
8 bit ALU that can add or subtract

The instructions:
00[00000]
ADD: adds contents of $1 and $2 and writes result to $3
00[XXXXX]
ADDI: Changes the contents of $3 to X, 2c Range -16 to 15
01[00000]
SUB: Subtracts contents of $2 from $1, writes result to $3
01[XXXXX]
BNEZ: Branch not equal zero, 2c, range -16 to 15 + 1
100[XXX]0
LOAD: Sends value contained in memloc X to $3, range 0 to 7
101[XXX]0
STORE: Sends value contained in $3 to memloc X, range 0 to 7
110[XX][YY]
MOVE: Sends value contained in register $X to register $Y
111[1111]
End: Plays a chime, indicates the program is over
