The registers inside the CPU, the machine code instruction set, and the ways in which the instructions interact with the registers and status flags are all intertwined. As you may recall, one of my ...

What we are going to do is design a simple 4-bit computer at the primitive logic gate and flip-flop level and then implement it in the technology of our choice I’ve often wondered what would happen if ...

MikroLeo is a discrete TTL logic-based microcomputer intended for educational purposes created by [Edson Junior Acordi], an Electronics Professor at the Brazilian Federal Institute of Paraná, Brazil.

[Scott Baker] is at it again and this time he has built a 4-bit single board computer based on the Intel 4004 microprocessor. In the board design [Scott] covers the CPU (both the Intel 4004 and 4040 ...

In 1971, Intel Corp. introduced its first microprocessor chip, the 4004. The 4-bit processor chugged along at a mere 104 KHz. In the 35 years since then, processor clock speeds—and performance—have ...
