All Rights Reserved. microcontroller is planned to use in portable and power critical applications. DoCD™ Debug Unit – it’s a real-time hard- ware debugger provides debugging capability of a whole SoC system. In contrast to other on- chip debuggers DoCD™ provides non-intrusive debugging of running application. It can halt, run, step into or skip an instruction, read/write any contents of microcontroller including all registers, internal, external, program memo- ries, all SFRs including user defined peripher- als. Hardware breakpoints can be set and con- trolled on program memory, internal and exter- nal data memories, as well as on SFRs. Hard- ware breakpoint is executed if any write/read occurred at particular address with certain data pattern or without pattern. The DoCD™ system includes three-wire interface and complete set of tools to communicate and work with core in real time debugging. It is built as scalable unit and some features can be turned off to save silicon and reduce power consumption. A spe- cial care on power consumption has been taken, and when debugger is not used it is automatically switched in power save mode. Finally whole debugger is turned off when de- bug option is no longer used. PERFOR M A N CE The following tables give a survey about the Core area and performance in Programmable Logic Devices after Place & Route (all CPU features and peripherals have been included): Device Speed grade Fmax ORCA 4E -3 50 MHz Core performance in LATTICE® devices For a user the most important is application speed improvement. The most commonly used arithmetic functions and their improvements are shown in table below. An improvement was computed as {80C51 clock periods} divided by {DR8051CPU clock periods} required to exe- cute an identical function. More details are available in core documentation. Function Improvement 8-bit addition (immediate data) 7,20 8-bit addition (direct addressing) 6,00 8-bit addition (indirect addressing) 6,00 8-bit addition (register addressing) 7,20 8-bit subtraction (immediate data) 7,20 8-bit subtraction (direct addressing) 6,00 8-bit subtraction (indirect addressing) 6,00 8-bit subtraction (register addressing) 7,20 8-bit multiplication 10,67 8-bit division 9,60 16-bit addition 7,20 16-bit subtraction 7,64 16-bit multiplication 9,75 32-bit addition 7,20 32-bit subtraction 7,43 32-bit multiplication 9,04 Average speed improvement: 7,58 Dhrystone Benchmark Version 2.1 was used to measure Core performance. The following ta- ble gives a survey about the DR8051CPU per- formance in terms of Dhrystone/sec and VAX MIPS rating. Device Target Clock frequency Dhry/sec (VAX MIPS) 80C51 - 12 MHz 268 (0.153) 80C310 - 33 MHz 1550 (0.882) DR8051CPU ORCA 4E 40 MHz 6452 (3.672) Core performance in terms of Dhrystones 268 1550 6452 0 2000 4000 6000 8000 80C51 (12MHz) 80C310 (33MHz) DR8051CPU (40MHz) Area utilized by the each unit of DR8051CPU core in vendor specific technologies is summa- rized in table below. Area Component [LC/PFU] [FFs] CPU* 1510 220 Interrupt Controller 110 40 Power Management Unit 10 5 Total area 1630 / 299 265 *CPU – consisted of ALU, Opcode Decoder, Control Unit, Program & Internal & External Memory Interfaces, User SFRs Interface Core components area utilization |
