We present a hardware/software implementation of the IEEE 802.15.3 MAC protocol. Processing-intensive and time-critical protocol tasks are handled by a protocol accelerator that is integrated on-chip with a 32-bit generalpurpose processor in order to achieve a moderate (20-40 MHz) system clock frequency. This enables low-power wireless devices compliant with this standard, providing high data rate, multimedia communication.One of the main tasks of the protocol accelerator is to analyze received or transmitted beacons. Based on the channel time allocations broadcast in the beacon and frame information stored in a hardware transmission queue, frames are transmitted without immediate control of the processor. Other features of the protocol accelerator include CRC generation, handling of immediate acknowledgment frames, and direct memory access.

SDL (Specification and Description Language) is popular for communication protocol design. SDL tools allow simulating and verifying SDL models. In this paper, we show how SDL models can be transformed into hardware/software implementations for embedded systems. Our design flow contains a lightweight operating system integration layer and a cosimulation framework that supports hardware/software partitioning.The design methodology has been applied to an implementation of the IEEE 802.15.3 MAC protocol. We present results from a prototypical system including a protocol accelerator.
