troller, but in comparison to its ancestor, DCD’s IP Core has a very low gate count architecture, giving 6 650 ASIC gates for the complete system with peripherals and the DoCD on-chip debugger. The Dhrystone 2.1 benchmark program runs 8.1 times faster than the original 80C51 at the same frequency. The performance results are claimed as more than twice those of the nearest competitive designs. The DT8051 includes a 2-wire DoCD on-chip debugger (TTAG), up to eight external interrupt sources, an advanced Power Management Unit, Timers 0&1, I/O bit addressable Ports, full duplex UART and interface for external SFR. Furthermore, DCD’s IP Core has a built-in support for the 2-wire TTAG interface - DCD Hardware Debug System: this version of the debug- ger is dedicated for applications, where a number of external pins is limited. The DT8051 is delivered with fully automated test bench and complete set of tests, allowing easy package validation, at each stage of SoC design flow. —by Graham Prophet DCD, www.dcd.pl/ipcore/33/dt8051/ Deep memory mixed-signal modular scopes A new range of mixed-signal oscilloscopes (MSOs) from Pico Technology combines the deep memory and high performance of the PicoScope 3000 Series with a 16-channel logic analyser. With a built-in function generator and arbitrary waveform generator also included, these oscilloscopes offer a multifunction test unit in a compact, USBpowered device. The new MSOs have two analogue channels with bandwidths from 60 MHz to 200 MHz, a maximum singlechannel sampling rate of 500 Msamples/ sec, and 100 MHz digital inputs. Buffer memory sizes range from 8 Msamples to 128 Msamples. You can use the deep memory with the serial decoding feature, capturing data using any of the two analogue and 16 digital inputs, giving you up to 18 channels. All of these The PicoScope MSO takes the form of a USB-powered module and displays on any PC. testing of mixed-logic designs. The PicoScope software includes all standard oscilloscope and spectrum analyser functions, as well as mask limit testing, segmented memory, advanced triggers and the serial decoding. Other builtin features include persistence displays with fast update rates, math channels, automatic measurements with statistics, and programmable alarms. Updates to the software are free of charge. can be decoded concurrently, even with a mixture of serial protocols. Serial data in I2C, UART/RS232, SPI, CAN bus, LIN and FlexRay formats can be decoded and displayed in binary, decimal or hexadecimal formats. The 16 logic inputs are organised in two banks, each of which has its own adjustable logic threshold to allow “Software includeS all Standard oScilloScope and Spectrum analySer functionS ” Trigger types include pulse width, interval, window, window pulse width, level dropout, window dropout, runt pulse, variable hysteresis, and logic. All triggering is digital, ensuring lower jitter, greater accuracy and higher voltage resolution than with analogue triggering. A free Software Development Kit (SDK) allows you to control the new scopes from your own programs. It includes example code in C, C++, Excel and LabVIEW, and can be used with any language that supports C calling conventions. The PicoScope software and SDK are compatible with Microsoft Windows XP, Windows Vista, Windows 7 and Windows 8. PicoScope 3000 Series MSOs are available from €785 for the 60 MHz PicoScope 3404 MSO to €1270 for the 200 MHz PicoScope 3406 MSO, including analogue probes, logic cables and a 5-year warranty. —by Graham Prophet Technology, Pico The mixed-signal display is in standard scope form, with analogue and logic traces. www.picotech.com www.edn-europe.com december 2012 | EDN EUROPE 13 http://www.dcd.pl/ipcore/33/dt8051/ http://www.picotech.com http://www.edn-europe.com
