“…Usually the compiler produces code that is 1.1 to 2 times slower than the ideal performance that we calculate assuming ultimately optimized assembly code for the particular implementation we have chosen. The only assembly-coded module that we used in this work is the affine transformation obtained from UWICL [17].…”

3D ultrasound (US) provides physicians with a better understanding of human anatomy. By manipulating the 3D US data set, physicians can observe the anatomy in 3D from a number of different view directions and obtain 2D US images that would not be possible to directly acquire with the US probe. In order for 3D US to be in widespread clinical use, creation and manipulation of the 3D US data should be done at interactive times. This is a challenging task due to the large amount of data to be processed. Our group previously reported interactive 3D US imaging using a programmable mediaprocessor, Texas Instruments TMS320C80, which has been in clinical use. In this work, we present the algorithms we have developed for realtime 3D US using a newer and more powerful mediaprocessor, called MAP-CA. MAP-CA is a very long instruction word (VLIW) processor developed for multimedia applications. It has multiple execution units, a 32-kbyte data cache and a programmable DMA controller called the data streamer (DS). A forward mapping 6 DOF (for a freehand 3D US system based on magnetic position sensor for tracking the US probe) reconstruction algorithm with zero-order interpolation is achieved in 11.8 msec (84.7 frames/sec) per 512×512 8-bit US image. For 3D visualization of the reconstructed 3D US data sets, we used volume rendering and in particular the shear-warp factorization with the maximum intensity projection (MIP) rendering. 3D visualization is achieved in 53.6 msec (18.6 frames/sec) for a 128×128×128 8-bit volume and in 410.3 msec (2.4 frames/sec) for a 256×256×256 8-bit volume.

“…Depending on the rotation angle, one of the volumes is selected as an input to our visualization program. The affine warp on MAP-CA was developed as part of the University of Washington Image Computing Library (UWICL) [17]. In the following paragraphs, we will describe the MAP-CA implementation of the 3D shear with the MIP rendering.…”

“…In selecting a test set of universal C intrinsics, we studied several image computing functions from the MAP UWICL for the MAP mediaprocessor, which was developed by the University of Washington [6]. In addition, we carefully evaluated the instruction sets from a collection of mediaprocessors (e.g., MAP, TriMedia, Pentium III, and TMS320C64X).…”

The architecture of mediaprocessors has become increasingly sophisticated to accommodate the need for more performance in processing various media data. However, due to the inability of mediaprocessor compilers to fully detect the parallelism available in a program and maximize the utilization of the mediaprocessor's on-chip resources, C intrinsics, which are hints to the compiler on which assembly instructions to use, have been employed to achieve better performance. Nonetheless, these intrinsics are mediaprocessor-dependent, thus limiting the portability of mediaprocessor software. To help increase the portability of mediaprocessor software, we have developed a Mediaprocessor Programming Interface (MPI), which translates one set of C intrinsics into another. In many cases, the translated code for the target mediaprocessor has similar performance to the code developed with native intrinsics. We believe that the MPI can facilitate the reuse of mediaprocessor software as well as the development of mediaprocessor-independent software.

“…Software libraries, such as the MAP UWICL for the MAP1000 and the MVP UWICL for the TMS32OC8O [13,14], provide functions that can serve as building blocks for developing higher-level algorithms and applications. Developers can quickly complete a mediaprocessor-based product using the modules in the libraries, which saves time by not having to develop optimized low-level functions and/or application programs, thus reduces time-to-market.…”

Mediaprocessors, such as Philips Trimedia and Hitachi/Equator Technologies MAP, combine the computational power of high-end DSPs with various 110 capabilities in a single programmable chip [1][2][3]. Due to their programmability, mediaprocessors have greater flexibility than ASICs and other special-purpose hardware. Early mediaprocessors, such as Texas Instruments TMS32OC8O (MVP) since its introduction in 1994 [4], have had limited success due to their difficulty in programming, insufficient computational power, and high cost. Fortunately, several newer mediaprocessors, which are available or under development, are easier to program, are less expensive, and/or have more computational power. However, due to the earlier difficulties and inherent uncertainties in the programmable solutions, mediaprocessor user companies (set makers) are often hesitant in adopting the mediaprocessors in their products. Furthermore, set makers still need to expend a lot of time and manpower in making a successful transition from hardwired to mediaprocessor-based products. Therefore, we introduce the Mediaprocessor (MP) Consortium, which aims to remove the barrier to the widespread use of programmable mediaprocessors. Through publications, web site, training courses, software libraries, and objective evaluations of mediaprocessors, the MP Consortium can increase the awareness of the benefits of mediaprocessors over ASICs, make the transition to mediaprocessor-based products easier for set makers, and help them attain full advantage of using mediaprocessors.
