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 ...

Anyone who thinks old computers only belong in a museum is wrong. We show how retro computers can still perform amazing and ...

asynchronous Processor modules/cores. In this paper, power, area performance parameters of 8-bit pipelined asynchronous processor is measured and compared over similar feature synchronous processor.

[c0pperdragon] set himself the task of designing a very capable 8-bit CPU using just 74HC type logic chips on a large plug-in breadboard. To emphasize the “bread” theme, he put the whole thing ...

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 ...

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 ...

Microcontrollers exist in almost everything, but can RISC-V satisfy the needs of this market? Is it small enough to replace 8-bit processors? What might help people migrate to a more modern processor ...
