G 2 HW Proposal OMAP based

G 2 HW Proposal 1: Pros/Cons • Pro: – Maximized reuse • EE and SW – Minimizes part qual • Con: – Space – Cost – Standby Power, Music Power – ST CPCAP desense • SW items: – New Audio solution • Leverage Vendor for driver development • Audio routing and switching – New GPS • CSR has full solution available up to the Android Location provider

G 2 AMS Based system block diagram Advantages Ø 2 X Music power reduction compared to OMAP based system. Ø Board space Advantage over OMAP based Disadvantages Ø High schedule risk from HW and SW perspective. Ø No next GEN IC planned by AMS Ø 128 m. SDR may not be available

G 2 HW Proposal 2: Pros/Cons • Pro: – Small, integrated power MGT – 2 X Music power reduction compared to OMAP based system. – Board space Advantage over OMAP based • Con: – New PM driver – New Charging/Metering • SW items: – Porting the Android to ARM 9 • Leverage Vendor for driver development • Audio routing and switching – New GPS • CSR has full solution available up to the Android Location provider

G 2 IMX Based System block diagram

G 2 HW Proposal 3: Pros/Cons • Pro: – Small, integrated power MGT – 30 -35 m. W power consumption • Con: - No POP packaging available hence more board space • SW items: – High Risk from SW – Android porting with third party – None of the wireless connectivity drivers available

Processor Selected • i. MX excluded due to its high standby power consumption and no POP package support. • EMA is excluded due to no POP package support. • If Custom RTOS considered the selection goes to AS 3536 due to its analog integration, Size, Nano compatible power performance. But it will be a schedule hit and unknown SW developmental cost. • Software and Schedule drives the selection to OMAP with Acceptable performance and size.

G 2 Primary PM Options • ST CPCAP – Pro: Maximized reuse (EE and SW), Minimizes part qual – Con: Space, Cost, Standby Power, ST CPCAP desense – Open items: headset detection/keys • National LP 3925 – Pro: Size, Power – Con: New PM driver (medium), New Charging/Metering (high), New HS-USB XCVR (low) – Open items: still reviewing spec to determine any open items, headset detection/keys, lighting control • ‘Discrete’ – Pro: Layout flexibility, Power, size/aspect ratio – Con: SW drivers – Open items: RTC, Battery metering, A 2 D, Control logic (on/off, reset, bus detection etc), headset detection/keys, lighting control

G 2 Other Investigated PM Options • TI CPCAP – Pro: Maximized reuse (EE and SW), Minimizes part qual – Con: Space, Cost, Standby Power, Switcher efficiency – Open items: headset detection/keys • TI TWL 6025 – Timing outside window • ‘Discrete’ – Pro: Layout flexibility, Power, size/aspect ratio – Con: SW drivers – Open items: RTC, Battery metering, A 2 D, Control logic (on/off, reset, bus detection etc), headset detection/keys

G 2 Music Decode Options • Cirrus Logic Decode + Audio DAC - Pro: Space, power - Con: SW development (high risk), maturity of solution for decode • NEC Decode + Audio DAC – Pro: In the market now – Con: size, SW • DAC 33 – Pro: all TI solution – Con: power, space, SW

GPS Selection • Power – BCM host based solution in LP is > full active tracking on both TI and CSR • Space – BCM & GDS 4 e are ~ parity. – TI 1281 leads due to integration w/ WLAN/BT/FM • Integration Effort – BCM is already integrated – TI/CSR estimated to ~ same effort • Market Experience – GDS 4 e is used in competitive fitness products: mature understanding of pedestrian issue etc. – BCM learning in the space has been primarily driven through Gault 1. 20751 was much more optimized for phone usage – TI: unproven experience in the space. Again driven more from cell phone applications

G 2 BT/Wi. FI Options • WL 1271 L (BT/Ant+(or BLE)/Wi. FI/FM) – Pro: Already integrated for Wi. FI, BT, Ant+, FM – Con: Ant+/BLE FW concurrency, A 3 DP/Ant+ FW concurrency • WL 1285 (BT/Ant+(or BLE)/Wi. FI/FM) – Pro: Migration path to TI integrated GPS – Con: Size, Ant+/BLE FW concurrency, A 3 DP/Ant+ FW concurrency – Investigating Cost (but would jump to 1281) • WL 1281 (BT/Wi. FI/Ant+/BLE/FM/GPS) – Pro: all radios integrated, size, cost, migration path to fully integrated solution from TI (G 3 custom Si) – Investigating A 3 DP concurrency with Ant+/BLE • BL 6450 (BT/Ant+(or BLE)/FM) – Pro: cost, size – Con: no Wi. FI, will not be used if Wi. FI is a requirement

G 2 BT Audio Considerations • Fully Featured: Telephony, A 2 DP Source/Sink – BT paging/slot/channel scheduling nightmare with Wi. FI and sensors (Ant+/BLE) – Implementation due to lack of client side support in current Android (HFP and A 2 DP) • A 2 DP

G 2 - EE RISK Risk Items GPS Antenna Performance Small device size is impacting resonant frequency and performance BT/Wi. Fi Antenna Performance – New Back button and small size is limiting design options for BT/Wi. Fi without impacting GPS Sensors Accuracy – MSP Accuracy on Wrist Low Power Audio – Non-platform audio solution Sche dule Risk Mitigation Plans Impa ct • Working with supplier for “tuning” GPS parts, working on multiple Mediu BT/Wi. Fi Solutions m Low • Working (simulating and building) on multiple BT/Wi. Fi Solutions – also considering dual band GPS & BT/Wi. Fi antenna High • Hire Algo developer • Schedule regular user trial testing Med • Mock up boards for early development • Regular code drops from CL. • Document requirements, design and communicate regularly. Use OMAP audio (high current drain)
