Skills

Summary

Excellent written and verbal communication capabilities.

Skilled in the areas of Micro architecture, Verilog/RTL design, Verification, and FPGA based emulation of SoC/ASIC subsystems and IP.

Experience with designs for mobile devices, embedded processor nodes, memory sub-systems, mesh interconnects, Ethernet NICs, enterprise class storage controllers, and various acceleration hardware for firmware offload.

Proven ability to organize design efforts and to deliver results working closely with marketing, architecture, design, verification, physical design, and firmware teams.

Key technical contributor, team leader skills, self-motivated, and committed to project success.

01/2014 – Present Mangstor Inc. Austin, TX

Principle Architect / Designer

Responsible for the Micro-architecture, Verilog/RTL design, Verification, FPGA based prototyping, and Documentation, of multiple complex hardware modules for an enterprise class, SSD (MX6300) and follow on Storage controller SoC products.

Overview of specific deliverables:

Highly parameterized Compute node (Xtensa processor based) and common I/O node hardware design (RTL). Nodes provide highly efficient and flexible virtual memory queue hardware (H/W). Working closely with Firmware (F/W) engineers to define and optimize the H/W for targeted “control plane” tasks.

Common switching logic for Compute and I/O nodes supporting interconnection as a systolic array (ie. Mesh Interconnect) with H/W and F/W based routing overrides.

Shared memory nodes used for Compute node intra-communications with H/W based access locking scheme. Shared memory nodes also support both H/W and F/W trace capture with time-stamps for debug and performance profiling.

Main memory (DDR3) client sub-system with multiple H/W acceleration features

(read / test / conditional modification / write operations) with client feedback. Highly parameterized RTL code for quick adaptation to follow on SoC devices and 3rd party DDR interface IP.

Hardware accelerator machine for XOR functions and LFSR based Multiplication for RAID / Erasure code generation and object based storage features. Recent
