Express Logic Offers Royalty-Free Support for LSIís ZSP Processor

12/22/2003 - Express Logic, Inc., the worldwide leader in royalty-free real-time operating systems (RTOS), announced ThreadX® support for LSI Logic's ZSP processor architecture.

Express Logic's ThreadX RTOS provides real-time embedded developers who use the ZSP processor with the most technically advanced multitasking solution on the market today. Express Logic's picokernelTM design results in very high-performance and extremely small memory footprint - requiring less than 4Kbytes for minimal usage. ThreadX also provides applications using LSI Logicís ZSP with significant technical innovations including extremely fast software timers and a mechanism to help reduce context switching called preemption-threshholdTM.

The ZSP family of licensable, synthesizeable cores are designed for a variety of demanding next generation consumer and networking applications. Based on a superscalar, multi-issue architecture, the ZSP400 is capable of performance up to 800 peak RISC MIPS at 200 MHz. The innovative open ZSP architecture utilizes a compact 16 bit instruction word coupled with native digital signal processing instructions optimized for voice, multimedia and digital communications, that can be employed in both client and infrastructure side wireless network applications, next-generation mobile communications and media-rich consumer applications.

The ZSP core family consists of increasingly higher performance cores with features that provide configurable memory subsystems and extensible instruction set architectures, comprehensive tools and modeling support for rapid SOC integration. The ZSP cores offer superior performance, code density, ease of use, and a flexible open architecture. ThreadX supports the ZSP by magnifying these benefits with a small, efficient, easy-to-use RTOS well suited to ZSP-targeted applications.

"ThreadX delivers important capabilities to our customers who are developing networking, wireless, voice and multimedia consumer applications,Ē says Jim Benefer, Senior Marketing Manager of LSI Logicís DSP Systems Division. ďThreadX has the small size and ease of use that help our ZSP processor fit our customersí needs."

ThreadX fully supports the ZSP 400/500/600 architectures and is committed to supporting all future members of the family.

"We are seeing increasing customer interest in LSI Logic's ZSP microprocessor solutions. Since the ZSP architecture addresses the same high-performance and cost sensitive network requirements that ThreadX does, we expect strong demand for our ZSP support package," says William E. Lamie, Express Logic's president. "Our ThreadX support for ZSP helps both current and new network application developers get better quality product to market in less time."

ThreadX for the LSI Logic ZSP architecture is available immediately from Express Logic. Pricing starts at $12,500 for a single design license, with no run-time royalties.
