This paper describes a Sandbridge Sandblaster system implementation including both hardware and software elements for a WiMax 802.16e system. The system is implemented on the fully functional multithreaded Sandblaster multiprocessor SB3010 SoC chip. The entire communication protocol, physical layer and MAC, has been implemented in software using pure ANSI C(More)
General-purpose processors have utilized complex and energy inefficient techniques to accelerate performance. In embedded DSP designs, power constraints have precluded general-purpose microarchitectural techniques. Rather than minimize average execution time, embedded DSP processors require the worst-case execution time to be minimized. Subsequently, Very(More)

We present an inexpensive multi-protocol communication system implemented entirely in software comprised of Global Positioning System (GPS), Wireless Local Area Network (WLAN) and Bluetooth (BT). All three communications protocols share the same Analog to Digital converter and are sampled at the same hardware sampling rate. The hardware sampling clock is(More)
This paper presents a SW reconfigurable platform, capable of executing in real time both analog and digital television protocols as NTSC, PAL, SECAM and DVB-H. Our platform is also capable of executing WiMAX at 2.9 Mbps in real time, as well as other mobile telephony protocols like 3G UMTS or CDMA200. SW reconfigurability and low power consumption makes our(More)
We present a tier 2 Software Defined-Radio platform (SDR), built around the latest Sandbridge Technologies’ multithreaded Digital Signal Processor (DSP) SB3500, along with the description of major design steps taken to ensure the best radio link and computational performance. This SDR platform is capable of executing 4G wireless communication standards such(More)
As wireless platforms converge to multimedia systems, architectures must converge to support voice, data, and video applications. From a processor architecture perspective, support for signal processing (both audio and video), control code, and Java execution will be required in a convergent device. Traditionally, wireless communications systems have been(More)
Software defined radios (SDRs) offer a programmable and dynamically reconfigurable method of reusing hardware to implement the physical layer processing of multiple communications systems. An SDR can dynamically change protocols and update communications systems over the air as a service provider allows. In this paper we present techniques for implementing(More)
In this paper, we present a software implementation of an LTE baseband receiver for both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) system on Sandblaster SB3500 which is based on the Sandblaster 2.0 architecture. The Sandblaster SB3500 is a compact and power efficient System on Chip (SOC) platform designed for wireless and multimedia(More)
