Embedded PowerPC and ARM development in Greenhills 'C', including coding LED and linker/loader files for new product bring-up plus mostly re-factoring BSP (board support package) code for easier code maintenance.

Part of the team implementing Solid State Drives.Working here was a big mistake unfortunately.All new projects were to be written in C++, the guy that hired told me the c++ code they write here is very C like and I'll have no problem, which was a lie. The other new hires straight out of college CS degrees wrote the most complicated C++ code I've never.

Primarily debugged ARM assembler and 'C' for cell phones, using Qualcomm tools and the Lauterbach in circuit debugger (ICD) with JTAG. Version control was done with Perforce. My main specialty was memory – SDRAM/FLASH(NAND/NOR) writing or fixing drivers to erase/reprogram FLASH and control DRAM timings. Another specialty was maintaining the secure.

Designed hardware and firmware for several enclosure management controllers for disk subsystems based on a Motorola MC68HC11 with an Adaptec 93c46 LVD SCSI controller using the SAF-TE protocol running on the 68HC11, Atmel ATmega8 for power supply voltage sensing and fan control, Vitesse SSC100 + VSC120 (MIPS based) microcontrollers for Fibre Channel with.

Product was a SCSI-to-SCSI bridge for Exabyte or DAT tape drives to emulate large reel-to-reel and expensive AS400 only tape drives. I wrote 8051 assembler for the SCSI bridge’s microcontroller to allow firmware updates from a tape cartridge to the micros FLASH.

Developed SCSI bridge firmware in x86 assembler to make a generic Exabyte tape drive emulate several makes of more expensive tape drives, used by small businesses with AS400 servers. Designed firmware to use the SCSI bridge to take SCSI medium changer commands and send them to a serially controlled jukebox. Designed firmware for the SCSI bridge to use a.

Maintained tape motion control firmware in 8051 assembler. designed and programmed 8051 controlled LED display. Developed the SCSI interface hardware for the company’s standard MT750 tape drive that normally shipped with a Pertec interface, Z8002 assembler code debugged using real-time trace hardware that showed address and data bus transactions with.

Developed hardware Q-bus disk controllers for PDP11 systems, my main task was to speed up and simplify three hard disk controllers based on a slow prototype using PLD to condense logic and improve timing. Designed the state machine using a PAL20RA10 PLD to get 8-bit internal data bus onto the 16-bit Q-bus at full bus rate to meet the new spec. The disk i/f.
