8051 MCU IP core is the industry's fastest
An 8051 MCU IP core, claimed to be the world’s fastest, has been introduced by DCD. Boasting a Dhrystone 2.1 performance rating of 0.27292 DMIPS/MHz, the DQ8051 IP core is 29.01 times faster than the original 80C51 chip operating at the same frequency. In addition, the IP core consumes as a little as 1.2µW/MHz. The closest competitor is 26 times faster than the original 80C51 chip and consumes almost two times more power than the DQ8051.
I/O interfaces include USB, Ethernet, I2C, SPI, UART, CAN, LIN, HDLC and Smart Card. The core is also equipped with a DoCD hardware debugger featuring Instruction Smart Trace (IST) technology, which only captures the addresses of executed instructions that are related to the start of tracing, conditional jumps and interrupts. This method not only saves time but also increases the size of the IST buffer and extends the trace history. Captured instructions are read back by DoCD-debug software, analysed and then presented to the user as ASM code and related C lines.
The DQ8051 is delivered with a fully automated testbench and a complete set of tests, enabling easy package validation at each stage of the SoC design flow. The technology independent can be used in both ASIC and FPGA technologies.
