1. Kyeounsoo Kim, P.A. Beerel, “A low-power matrix transposer using MSB-controlled inversion coding”, The First IEEE Asia Pacific Conference on ASICs, 1999. AP-ASIC '99.

Abstract: This paper proposes a low-overhead MSB-controlled inversion coding technique to reduce the transition activity in a matrix transposer a commonly used component in 2-dimensional discrete cosine transform (DCT) and inverse DCT (IDCT) applications. A family of designs is identified in which this technique is applied to different bit slices of the matrix data and the optimal design within the family is determined using transition activity analysis driven by real image sequences. Our results suggest that the optimal design using MSB-controlled inversion coding yields power savings of 33% for DCT data and 46% for IDCT data. These results are remarkable since existing bus-invert coding techniques have high overheads and are only effective for system-level high-capacitive buses.

2. Kyeounsoo Kim, P.A. Beerel, “A high-performance low-power asynchronous matrix-vector multiplier for discrete cosine transform”, The First IEEE Asia Pacific Conference on ASICs, 1999. AP-ASIC '99.

Abstract: This paper proposes a high-performance low-power asynchronous architecture for matrix-vector multipliers of a constant matrix by a vector which are typically used in discrete cosine transform (DCT) and inverse discrete cosine transform (IDCT) applications. The architecture takes advantage of the statistics of DCT and IDCT data that suggest that the input data have mostly zero or small values. It avoids unnecessary arithmetic operations by quickly terminating multiplication by zero and significantly reduces power and delay when operating on a small-valued data by adaptively controlling effective word lengths using fine-grain bit-partitioning and speculative completion sensing.

3. Kyeounsoo Kim · Jong-Seog Koh · Ki-Bum Suh · Jong-Wha Chong, “An efficient frame memory interface of MPEG-2 video encoder ASIC chip”, 1999. ICCE. International Conference on Consumer Electronics.

Abstract: In this paper an efficient frame memory interface of an MPEG-2 video encoder is presented. The proposed architecture takes about 58% less hardware area than the existing architecture (Kim et al. 1997), and results in reducing the total hardware area of the video encoder up to 24.3%.

4. P.A. Beerel, Sangyun Kim, Pei-Chuan Yeh, Kyeounsoo Kim, “Statistically optimized asynchronous barrel shifters for variable length codecs”, 1999. Proceedings. 1999 International Symposium on Low Power Electronics and Design.

 

Abstract: This paper presents low-power asynchronous barrel shifters for variable length encoders and decoders useful in portable applications using multimedia standards. Our approach is to create multi-level asynchronous barrel shifters optimized for the skewed shift control statistics often found in these codecs. For common shifts, data passes through one level, whereas for rare shifts, data passes though multiple levels. We compare our optimized designs with the straight-forward asynchronous and synchronous designs. Both pre- and post-layout HSPICE simulation results indicate that, compared to their synchronous counterparts, our designs provide over a 40% savings in average energy consumption for a given average performance. 

 

5. Kyeounsoo Kim, Jong-Seog Koh, “An area efficient DCT architecture for MPEG-2 video encoder”, IEEE Transactions on Consumer Electronics, Mar 1999.

 

Abstract: This paper presents an area efficient VLSI architecture of transform coding module for MPEG-2 video encoder. This module consists of 2-D DCT and 2-D IDCT, Q and IQ, and zigzag and alternate scan conversion circuits. Hardware cost and performance of this module are mainly affected by the 2-D DCT and 2-D IDCT. In the proposed architecture, it is shown that a single 1-D DCT/IDCT could take the roles of the 2-D DCT and 2-D IDCT. It is capable of reusing a single 1-D DCT/IDCT four times. It is based on the row-column decomposition technique. It can be achieved through precise timing schedules. Intuitively, three 1-D DCT/IDCT and a matrix transposition memory could be saved as compared to the conventional architectures, which usually use two one-dimensional transforms and transposition memory. Even though there are some extra circuits due to timing controls and processing sequence schedules, this architecture takes about 24% and 50% respectively less area than the architectures published by Miyazaki et al. (1993) and by Matsiu et al. (1994). This design and implementation are applicable to the MPEG-2 video encoder accepting NTSC and PAL image formats in which the number of clocks to be allocated during a macro block period is 1320 for 54 MHz operating clock. To reduce its processing time, the proposed architecture uses a 3-bit serial distributed arithmetic method. As a result, this architecture can be characterized to maximize the utilization of the hardware resources, end can be used for encoders having a similar structure as the MPEC-2 video encoder. It also can be applied to the ASIC chips for multimedia services especially requiring low hardware complexity.

Abstract: In this paper, a VLSI architecture for DPCM Hybrid Coding Loop (DHCL), which consists of 2D-DCT, quantization, scan conversion, inverse quantization and 2D-IDCT, is presented. The architecture of the DHCL is designed to handle macroblock data within 1320 cycles and suitable for MPEG-2 video encoder accepting NTSC and PAL image formats. Only single 1-D DCT/IDCT is used for the design instead of 2-D DCT and IDCT to reduce the hardware size, and 3-bit serial distributed arithmetic architecture is adopted for 1-D IDCT to reduce the processing time in this architecture. As the result, the maximum utilization of hardware can be achieved, and power consumption can be minimized. The proposed designs can be operated on 80 MHz clock. The area is 50% smaller than the previous methods with 2D-DCT and IDCT. The experimental results show that the accuracy of DCT and IDCT meet the IEEE specification.

 

7. Kyeounsoo Kim, Peter A. Beerel, “MSB-Controlled Inversion Coding for a LowPower Matrix Transposer”, IEE Electronics Letters, Oct 1999.

 

Abstract: The increasing demand for portable and wireless multimedia applications that rely on limited battery energy has made low power architectures and designs for these applications critical. Since real-time matrix transposition consumes a large fraction of the power in multi-dimensional image and signal processing, low-power matrix transposers are particularly important.

 

8. Kyeounsoo Kim, Peter A. Beerel, Youpyo Hong, “An asynchronous matrix-vector multiplier for discrete cosine transform”, Proceedings of the 2000 International Symposium on Low Power Electronics and Design.

 

Abstract: This paper proposes an efficient asynchronous hardwired matrix-vector multiplier for the two-dimensional discrete cosine transform and inverse discrete cosine transform (DCT/IDCT). The design achieves low power and high performance by taking advantage of the typically large fraction of zero and small-valued data in DCT and IDCT applications. In particular, it skips multiplication by zero and dynamically activates/deactivates required bit-slices of fine-grain bit-partitioned adders using simplified, static-logic-based speculative completion sensing. The results extracted by both bit-level analysis and HSPICE simulations indicate significant improvements compared to traditional designs.

9. Sunan Tugsinavisut, Youpyo Hong, Daewook Kim, Kyeounsoo Kim,·Peter A. Beerel, “Efficient asynchronous bundled-data pipelines for DCT matrix-vector multiplication”, IEEE Transactions on VLSI Systems, May 2005.

 

Abstract: This paper demonstrates the design of efficient asynchronous bundled-data pipelines for the matrix-vector multiplication core of discrete cosine transforms (DCTs). The architecture is optimized for both zero and small-valued data, typical in DCT applications, yielding both high average performance and low average power. The proposed bundled-data pipelines include novel data-dependent delay lines with integrated control circuitry to efficiently implement speculative completion sensing. The control circuits are based on a novel control-circuit template that simplifies the design of such nonlinear pipelines. Extensive post-layout back-end timing analysis was performed to gain confidence in the timing margins as well as to quantify performance and energy. Comparison with a synchronous counterpart suggests that our best asynchronous design yields 30% higher average throughput with negligible energy overhead.
