Served as firmware architecture design team member. Designed and developed principle software modules for multi-threaded DSL subsystem using C/C++.

• Centralized message processing and solved queue-overrun issues seen prior by developing RTOS tasks used to manage full-duplex messaging between MIPS34k and microMips subsystem.

• Resolved complexities for end-user by creating network-on-chip framework used to configure communication links between hardware blocks by describing each link in Excel then parsing to produce C code.

• Created ISR framework on memory-constrained MIPS microAptiv system, processing hardware interrupts and exceptions, providing multi-tasking and allowing for quick diagnosis / resolution for processor exceptions.

• Designed SW driver for Synopsys DMA controller using C++ and MIPS assembly code; complexities of DMA hardware were encapsulated in driver, providing user with clean and simple interface.

Developed C/C++ code and application tools for 16-port DSL solution. Firmware team member.

• Enhanced NUCLEUS RTOS kernel for profiling task and ISR execution times by modifying task switching point, resulting in clear picture of tasks that needed optimization.

• Delivered reliable method for message transport and reception, creating full-duplex mailbox interface for message transmission to multi-threaded vector processor in DSL subsystem.

• Produced framework using TCL for testing different register combinations within SERDES hardware block, allowing user to employ very simple customized script format for accessing registers using names instead of hard-coded addresses; tool proved invaluable for LSI engineers bringing up SERDES interface.

Performed as firmware team member and C++ Windows application developer.

• Reduced debugging time by developing multi-threaded Windows application using MFC C++ to capture and display all EOC diagnostic frames sent between DSL modems.

• Designed Linux VDSL network driver that was integrated into customer system. Reduced driver execution time using ARM inline assembly in order to maximize hardware features.

• Automated DSL Ethernet testing with Compass traffic simulator by developing MFC C++ application, which accessed Compass driver API, testing range of Ethernet-frame settings specified by user and displaying results in graphical format for easy analysis.
