The first product of Quickchip is an 8051 compatible embedded processor core that achieves six times the performance of a standard 8051 micro controller. While a standard 8051 micro controller takes 12 clock cycless for a machine cycle the QUIC_8051 only takes two.
For an efficient debugging, a QUIC_8051 based FPGA can be connected to a standard 8051 In-Circuit Emulator. Unlike other embedded controller cores that come along with an on-chip debug module with limited functionality, a slow communication channel, and additional FPGA resource usage, QUIC_8051 based FPGA designs can be debugged with the high-level feature set and the comfort of an In-Circuit Emulator. No on-chip debug module exhibits such features an In-Circuit Emulator does like code coverage and performance analysis.
8051 compatible embedded processor core
Overview
Key Features
- QUIC_8051 is an 8051 compatible processor core for FPGA implementation.
- It is available in the form of EDIF net lists for different FPGA families. The core consists of:
- CPU
- Registers
- RAM (256 Byte)
- Timer 0, 1, and 2
- UART
- Interrupt Controller
- Port 2
- QUIC_8051 is compatible to the original 8051 micro controller that was designed by Intel in 1979. However, it is not identical. The main difference is the fact that QUIC_8051 executes the instructions six times faster than the original 8051 when both controllers are clocked at the same frequency. The peripherals, however, are not speeded up.
