The nucleus of the ST9 comprises a core that includes the CPU, the register file, interrupt and DMA controllers, and the memory-management unit (MMU). The MMU lets you address as much as 4 Mbytes of ...

While regular Hackaday readers already know how to blink a LED with a microcontroller and have moved onto slightly more challenging projects such as solving the Navier-Stokes equations in 6502 ...

Embedded microcontrollers are the original SoC devices. In the last few years FPGA and PLD manufacturers have proffered the term "System- on- a Programmable Chip" (SOPC) which captures the idea of ...

For a number of reasons, including cost, embedded microprocessors have been required to take on tasks for which they are not always well suited. Frequent interruptions from the outside world is one ...

Applications for the R4xxx µPs range from games to laser printers to workstations. Most R4xxx processors implement the MIPS III-architecture instruction set, which provides 64-bit integer registers, ...
