This paper describes the design and implementation of a version of the 8051 microcontroller, one of the most commercially used microcontrollers in FPGA with reconfigurable instruction set.

Multi-CPU, 8051 instruction-set-compatible parallel controller executes up to 300 MIPS in Actel Axcelerator FPGA and features concurrent real-time monitoring/debugging of all 9 CPUs via JTAG using ...

Californian start-up MicroCore Labs has announced an 8051 soft processor core, four of which will fit into 1227 LUTs on a Xilinx Artix-7 FPGA. The core is called MCL51. “Because it is based on a ...

Although 8051-compatible microcontrollers with SPI ports are available, a lower-cost device with an SPI port bit-banged through GPIO pins often suffices. The code shown here takes advantage of ...

At the introduction of the 12,000 gate 32bit ARM Cortex M0 recently, an ARM spokesman told EW the M0 was close to the 10,000 gates normally occupied by the 8bit 8051 microcontroller. Inspired by this, ...

The 8051 8-bit microcontroller just keeps plugging away, adding new peripherals, speed grades, and packaging. Among the latest advances is Dallas Semiconductor's 8051 implementation that delivers a ...

Many designers using 8-bit 8051 microcontrollers as the core of their systems face a challenge when updating the performance of their designs. Historically, performance upgrades have often required a ...
