Design Outcomes of ARM Developers: Comparing ARM Developments to those of Freescale, AMD, Intel, Microchip and TI
Embedded Market Forecasters, Aug 2009
In this report, EMF documents its findings of developer usage of embedded processors enabling developers using ARM architectures to understand what similar developers are experiencing and to be able to compare ARM-based design outcomes with other processor families. This information is based upon the responses of more than four hundred eighty embedded developers to the detailed 2009 EMF survey.
In this report, EMF documents its findings of developer usage of embedded processors enabling developers using ARM architectures to understand what similar developers are experiencing and to be able to compare ARM-based design outcomes with other processor families.
It is estimated that there are over 70,000 embedded developers designing with ARM architecture. The purpose of this report is twofold: To present the design experiences of ARM developers and to present comprehensive comparative data from which the readers can easily examine how ARM developments compare with developers using Freescale, Intel, AMD, Microchip and TI.
In the first section of this report, for the five most used ARM architectures we present design outcome measures including number of developers per project; time from design start to product shipment, percent of designs cancelled, percent of designs completed ahead of or behind schedule, the percent of final designs that are within 20% of pre-design expectation (for Performance, Systems Functionality, Features & Schedule), and the issues developers report as being of most concern In their embedded developments.
In the 2nd section of the report (Appendix), EMF presents the entire 2009 EMF Embedded Developer Survey results (101 Tables) cross tabbed by architecture (8-bit, 16-bit, 32-bit, 64-bit, 128-bit, DSP, FPGA, Dual Core, Multicore, Multithread) and processor family (ARM Freescale, Intel, AMD, Microchip and TI.
The five most used ARM architectures are: ARM7TDMI, ARM920T, ARM922T, ARM926EJ-S, and ARM11MPCore.
COMPARATIVE DATA PRESENTED FOR THESE FIVE ARCHITECTURES AND INDUSTRY AVERAGES:
- Most significant issues impacting users embedded software development
- Number of software developers per project
- Number of new and modified source lines of code
- Total number of source lines of code
- Types of sensors and devices used by prime contractors
- Months from design start to product shipment
- Percent of designs cancelled – and number of months run before cancellation
- Percent of designs completed ahead of schedule
- Percent of designs completed behind schedule – and number of months behind
- Percent of designs outsourced
- Comparing final design results to pre-design expectations
- Percent of final designs that are within 30% of pre-design expectations for Performance, Systems Functionality, and Features & Schedule
- Options if final designs are not within acceptable ranges
- Percent of total development costs spent on testing
- Percent of total development time spent on unit testing
