Job description

Job Location : Bangalore

Exp : 9 - 13 Years

Mandate skills –

  • CPU performance analysis of Arm v8 and v9 Cortex A CPU IP.
  • System performance analysis for Arm total compute solution.
  • Frequency, Cache, Latency and Bandwidth sweep analysis.
  • Workloads bring up and characterization.
  • Workload reduction (Sim pointing) flow enablement

PRINCIPAL DUTIES AND RESPONSIBILITIES :

  • Experience in designing and developing low-level software / firmware using C, C++, and ARM assembly for high-performance, resource-constrained embedded systems.
  • Expert, hands-on knowledge of on ARM v8 / v9-A series CPU architectures. Deep knowledge of the RISC-V ISA is a significant advantage.
  • Proven expertise in ARM system specifications, including hands-on implementation or extensive customization of PSCI (Power State Coordination Interface), SCMI (System Control & Management Interface), and ARM Trusted Firmware-A (TF-A),.
  • Deep understanding of System on Chip (SoC) architecture, including hardware coherency (CPU-to-CPU and I / O coherency), cache management, and the intricacies of Memory Management Units (MMU) and Translation Lookaside Buffers (TLB).
  • Extensive experience with system power management architectures : Low Power Modes (LPM) and CPU idle / active state management.
  • Mastery of the C programming language for writing robust, efficient, and portable firmware and system-level code.
  • In-depth knowledge of boot architecture and secure boot sequences, including hands-on experience with UEFI, ARM Trusted Firmware-A (TF-A), ACPI specification and bootloaders.
  • Proven expertise in system software fundamentals : OS kernel internals, task scheduling, atomics, synchronization primitives, and memory management.
  • Expertise in embedded systems SW design, including real-time operating systems (RTOS). Proven experience with the Zephyr RTOS for prototyping, driver development, and power management is highly desirable.
  • Familiarity with the internals of OS kernels (Linux or Windows) and their interaction with CPU and SoC features. Experience in device driver development is an added advantage.
