File Size : 116 KB Manufacturer:FREESCALE Description:The HMU16/HMU17 multipliers are equipped with two 16-bit Output Registers (MSP and LSP) which are provided to hold the most and least signiﬁcant portions of the resultant product respectively. The HMU16 uses independent clocks (CLKM and CLKL) for latching the two output registers, while the HMU17 uses a single clock input (CLK) along with the Product Latch Enable (ENP). The MSP and LSP Registers may also be made transparent for asynchronous output through the use of the Feed through Control (FT). There are two output conﬁgurations which may be selected when using the HMU16/HMU17 multipliers. The ﬁrst conﬁguration allows the simultaneous access of the most and least signiﬁcant halves of the product. When the MSPSEL input is LOW, the Most Signiﬁcant Product will be available at the dedicated output port (P16-31/P0-15). The Least Signiﬁcant Product is simultaneously available at the bidirectional port shared with the Y-inputs (Y0-15/P0-15) through the use of the LSP output enable (OEL). The other output conﬁguration involves multiplexing the MSP and LSP Registers onto the dedicated output port through the use of the MSPSEL control. When the MSPSEL control is LOW, the Most Signiﬁcant Product will be available at the dedicated output port; and when MSPSEL is HIGH, the Least Signiﬁcant Product will be available at this port. This conﬁguration allows access of the entire 32-bit product by a 16-bit wide system bus.
