Software-defined radio (SDR) is an emerging technology that facilitates having multiple wireless communication protocols on one device. Previous work has shown that current W-CDMA, GPS, GSM, and WiMAX applications can run on this class of device while consuming significant processing power. Next generation wireless networks require speeds in excess of 50Mbps. Some of the fastest AES software implementations only achieve 20Mbps on our reference platform. In order to have secure software-defined radio, the security processing gap must be addressed. This paper presents instruction set architecture (ISA) extensions for the Sandblaster DSP. The Sandblaster DSP is a multithreaded processor for SDR that issues multiple operations each cycle and supports vector operations.

“…It performs semantic analysis of input programs and automatically recognizes saturating arithmetic in ANSI C [8]. For example the single-instruction loop for an inner product is generated automatically from the following source: int i, s; for (I = 0, s = 0; I < N; i++) { s += A[k]*A[k]; } The Sandblaster simulator is capable of executing over 100 million instructions per second on a 3GHz x86 computer [9]. The Sandblaster RTOS is capable of multiplexing an arbitrary number of software threads onto hardware threads.…”

Abstract. 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 programming language and it executes in real time. In this paper, we also present a radio propagation analysis specific to the Samos island at the workshop location, and the DSP execution performance.

“…Rewrite each application with the new operations provided as intrinsics and rerun the simulations to determine the new cycle count for each application. This process is simplified by the Sandblaster architecture Description Language (SaDL) [8]. SaDL provides an abstraction of the Sandblaster architecture and implementation into a single database, which guides the generation and optimization of the Sandbridge tool chain.…”

“…Each application, which is written in C, is compiled with full compiler optimizations including vectorization, loop unrolling, software pipelining, code motion, function inlining, and peephole optimizations [18]. Portions of the code that use the most cycles are then identified using the Sandbridge Software Tools [8].…”

Software defined radios, which provide a programmable solution for implementing the physical layer processing of multiple communication standards, are widely recognized as one of the most important new technologies for wireless communication systems. Emerging communication standards, however, require tremendous processing capabilities to perform high-bandwidth physical-layer processing in real time.In this paper, we present instruction set extensions for several important communication algorithms including convolutional encoding, Viterbi decoding, turbo decoding, and Reed-Solomon encoding and decoding. The performance benefits of these extensions are evaluated using a supercomputer class vectorizing compiler and the Sandblaster lowpower multithreaded processor for software defined radio. The proposed instruction set extensions provide significant performance improvements, while maintaining a high degree of programmability.
