3 CPU Core Information 5 CW6631B Bluetooth Audio Player Microcontroller Version 1.0.0 Copyright ©2015, www.appotech.com. All Rights Reserved. 3 CPU Core Information 3.1 Architecture The AXC51-CORE of CW6631B is fully compatible with the MCS-51TM instruction set. The AXC51-CORE employs a pipelined architecture that greatly increases its instruction throughput over the standard 8051 architecture. In a standard 8051, all instructions except for MUL and DIV take 12 or 24 system clock cycles to execute, and usually have a maximum system clock of 12MHz. By contrast, the AXC51-CORE executes most of its instructions in 1 system clock cycle. With system clock running at 48 MHz, it has a peak throughput of 48 MIPS running in on-chip SRAM area. 3.2 Instruction Set The instruction set of the AXC51-CORE is fully compatible with the standard MCS-51TM instruction set; standard 8051 development tools can be used to develop software for the AXC51-CORE. All instructions of AXC51-CORE are the binary and functional equivalent of their MCS-51TM counterparts, including op-codes, addressing modes and effect on PSW flags. However, instruction timing is different than that of the standard 8051.
