Komponent-programmering med forskellige serielle protokoller

JTAG Technologies, der er en førende leverandør af IEEE Std 1149.x baserede programmeringsværktøjer, udvider nu med support af andre serielle protokoller (in english). 

JTAG Technologies, a leading world-wide provider of board test and device programming tools based chiefly on IEEE Std 1149.x, has broadened its portfolio by offering device
programming solutions for an array of serial bus types, including SMBus, SPI, I2C and MicroWire. Classified by their Serial Controlled IC Programmer (SCIP) grouping, JTAG
Technologies announces support for the in-system programming of devices from the world's leading silicon vendors.

SCIP has solved several difficulties: Whilst many highly integrated microprocessors, DSPs and CPLDs use the JTAG (IEEE Std. 1149 or 1532) Test Access Port as the interface to program internal flash memory, some devices use non-standard instructions and protocols for the communication. What's more, other, generally smaller footprint, devices may use a different physical interface entirely; one that often uses fewer pins than the standard boundary-scan four or five pin TAP.

To enable manufacturers of PCBs using multi-vendor, multi-protocol processors JTAG Technologies leveraged existing knowledge of serial programming via regular JTAG to support busses such as SMBus, SPI, I2C and MicroWire.

So that users can modify existing hardware to cope with the various different  programming interfaces JTAG Technologies have added further modules to their existing 'SCIL' (Scan Configurable Interface Logic) range.

The new range of SCIL modules are supplied as 'swappable' interfaces that can convert JTAG DataBlaster hardware (eg JT 37x7 or JT 3710) into a protocol-specific device programmer or tester.
