Linux PDA vendor to demo RISC/DSP wares

Jan 31, 2005 — by Henry Kingman — from the LinuxDevices Archive — views

Canadian Linux PDA specialist Empower Technologies has opened a US subsidiary in Redmond, Wash. The subsidiary will demonstrate a Linux environment running on a dual-core Texas Instruments (TI) RISC/DSP chip at the TI Developer Conference (TIDC), set for Feb. 15-17 in Houston, Texas.

According to Empower, TIDC will offer more than 100 technical sessions and hands-on workshops where attendees can learn about signal processing technologies, such as HPA (high-performance analog), DSP (digital signal processing), DLP (digital light processing), microcontroller, microprocessor, FPGA (field programmable gate array) and complementary technologies.

Empower joined TI's DSP third-party network in December of 2004, and its US subsidiary is among five top-level sponsors of TIDC for 2005.

Empower's LinuxDA for OMAP5910

Empower announced it would port its LinuxDA Embedded O/S (LEOs) to the TI OMAP5910 in September of last year, adding a month later that it planned to ship a $200 PDA and a RISC/DSP development kit for portable data terminals (PDTs) based on the platform. The company says it will demonstrate both offerings at TIDC, along with a compact multi-function home entertainment device codenamed “Osaka.”

The PowerPlay 1x PDA

Empower describes the PowerPlay 1x as an inexpensive PDA that will support add-on modules such as an MP3/4 player, digital voice recorder, camera, and mobile phone. It will have a 16-bit color display, 32MB of Flash, and 64MB of DRAM.


Empower's LDK5910 will include an embedded processor module based on an OMAP5910 CPU, which integrates an ARM925 core with a TI TMS320C55x DSP (digital signal processor). The LDK5910 also includes:

  • Interface display module and NEC QVGA (320 x 240) 16-bit TFT LCD
  • LAN/expansion module with USB host and client ports, 10baseT Ethernet, and HP logic analyzer debugging port
  • I2S AIC 23 power amplifier, speaker, headphones, and microphone connections
  • LEOs runtime and development kit

The LDK5910 will be priced at $900. No availability date has been set.


The Osaka is a compact, all-digital audio system expected to ship next fall, according to Empower. The device will include a clock radio, MP3 player, CD player, and a DVD player, in addition to a PDA with a QVGA display.
