Usually, designing a CPU is a lengthy process, especially so if you’re making a new ISA too. This is something that can take months or even years before you first get code to run. But what if it ...

The 8-Bit Guy is building his dream computer, heavily inspired by the Commodore 64. Before we go into what this computer will do and what capabilities it will have, it’s important to note the 8 ...

Synchronous processors which consume more than 40 % of power in clock circuitry are being conveniently replaced by low power delay-insensitive (DI) asynchronous Processor modules/cores. In this paper, ...

The complete system with peripherals and the DoCD debugger needs just 6 650 ASIC gates, when a standalone CPU utilizes little else than 3k gates. The DT8051 is an area optimized tiny soft core of a ...

the 8088 only had an 8-bit data bus. This small difference would be the key to the wider use of the 8088 later. In the late 1970s and early 1980s, the personal computer industry was just starting.

Connected to a control unit, the ALU slices were strung together to make larger processors (8-bit, 16-bit, etc.). They included inputs and outputs for borrow and carry bits (addition and ...

16-bit and 8-bit microprocessors manufactured every year (see microcontroller). A 64-bit computer is not twice as fast as its 32-bit predecessor. The 64 bit "word size" is only one aspect of ...

The Apple Macintosh debuts in 1984. It features a simple, graphical interface, uses the 8-MHz, 32-bit Motorola 68000 CPU, and has a built-in 9-inch B/W screen.
