Study Notes
Computer Architecture
- The Memory Address Register (MAR) is described as '4096 x 16'.
- The Control Unit is responsible for controlling the register and memory.
Registers
- The 'OUTR' register is used to output data from the computer.
- The 'FGO' flag is used for conditional jumps, and if set to 1, the next instruction will be skipped.
Instructions
- 'ION' instruction is used to initialize the Output Register (OUTR).
- 'RR' instruction is used to rotate the contents of the Accumulator Register (AC) right.
Register Control
- Control inputs associated with registers include Load, Count, and Clock.
- The data inputs for the register come from the Output of the Adder and Logic Circuit.
Adder and Logic Circuit
- The Adder and Logic Circuit has two sets of inputs.
- D0T5 performs the OR operation in the system.
Gate Structure
- The gate structure controls the loading of data into the AC register.
Input/Output Devices
- In modern computers, I/O devices are commonly connected to the CPU and Memory using a bus arrangement.
